Further, in a camera-integrated VTR, an image based on a captured subject is recorded on a magnetic tape, and the recorded image can be reproduced by a video reproducing device and displayed on a monitor or the like. In this case, the camera-integrated VTR is capable of converting the aspect ratio of the recorded video and reproducing it.

[0005]

By the way, in this type of camera-integrated VTR, as shown in FIGS. 16A to 16D, the camera-integrated VTR is, for example, 0 degree with respect to the central axis of the lens. , VT with 180 degrees, 90 degrees, and -90 degrees, the camera integrated VT
According to the rotation of R, the viewfinder 1 also rotates. That is, the Viewfinder 1 has a camera-integrated VTR of 180

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

(1) First Embodiment (1-1) Structure of Video Recording Section In FIG. 1, reference numeral 10 denotes a camera-integrated VTR to which the present invention is applied as a whole, and a subject 12 obtained through a lens 11 is shown. Image pickup light LA1 of CCD (Charge Coupled Dev
Light is received by the imager 13 made of ice or the like. The imager 13 converts the imaging light LA1 into an electrical imager signal S1 corresponding to the subject image and sends it to the camera signal processing circuit 14 including an encoder or the like.

The camera signal processing circuit 14 uses, for example, the luminance signal Y, the chroma signals C and RG based on the imager signal S1.
A video signal S2 including a B signal and a composite video signal (or a signal obtained by digitizing the composite video signal) is generated, and this is sent to the recording circuit 16 and the on-screen display circuit 17 of the video recording unit 15, respectively. To do.

At this time, the rotation angle detection unit 1 of the image recording unit 15
When the switch of the switching circuit 19 is connected to the contact 19A, the automatic rotation angle detector 20 detects the rotation angle signal S3 based on the rotation angle according to the rotation of the VTR 10 with a built-in camera and causes the microprocessor 21 to operate. Send out. In addition, when the switch of the switching circuit 19 is connected to the contact 19B, the rotation angle detection unit 18 detects the rotation angle signal S3 based on the rotation angle of the camera-integrated VTR 10 by the rotation angle manual detector 22. It is sent to the microprocessor 21.

Further, when the switch of the switching circuit 19 is connected to the contact 19C, the rotation angle detector 18 is in the OFF state without detecting the rotation angle, and the rotation angle signal S3 based on the OFF state is processed by the microprocessor. 21. In this case, the switching circuit 19 includes the contacts 19A to 19A.
The connection of C can be switched by the designation of the user.

The microprocessor 21 includes a switching circuit 1
When the rotation angle signal S3 input from 9 is discriminated and, as a result, it is determined that the rotation angle is detected, the rotation angle signal S3 is converted into a format having an angle of, for example, 0 to 360 degrees to obtain the rotation angle data. Generate D1. Further, the microprocessor 21 synchronizes the rotation angle data D1 with the video signal S2 corresponding to the rotation angle data D1 and sends it to the recording circuit 16.

In this case, the recording circuit 16 is, for example, 8 [mm].
The video signal S2 is recorded in the video area on each track of the recording medium made of tape, and the rotation angle data D1 corresponding to the video signal S2 is recorded in the sub-code area corresponding to the video area on each track. Further, in this case, the recording circuit 16 records the rotation angle data D1 for each field or every several fields. Thus video recording unit 1
5 is capable of recording the rotation angle data D1 corresponding to the rotation of the camera-integrated VTR 10 in the recording circuit 16 together with the video signal S2.

The microprocessor 21 also generates a control signal S4 based on the rotation angle signal S3 and sends it to the on-screen display circuit 17. The on-screen display circuit 17 adds the control signal S4 to the video signal S2 corresponding to the control signal S4 to add the video addition signal S.
5 is generated and sent to the view finder 23.

As a result, as shown in FIG. 2, the visual finder 23 receives the video signal S according to the video addition signal S5.
The image based on 2 and the arrow a indicating the rotation direction of the camera-integrated VTR 10 based on the control signal S4 are displayed.
Therefore, the user who operates the camera-integrated VTR 10 can confirm whether or not the direction of the arrow a displayed on the viewfinder 23 and the rotation direction of the image to be displayed on the monitor (not shown) match. It is made possible.

Further, when the microprocessor 21 determines the rotation angle signal S3 input from the switching circuit 19 and as a result determines that the rotation angle detection unit 18 is in the off state, the microprocessor 21 determines, for example, 360 according to the off state. The rotation angle data D1 is generated by numerically converting it into a format having an angle larger than the degree and is sent to the recording circuit 16. In addition to this, the microprocessor 21 generates a control signal S4 on the basis of the rotation angle signal S3 to generate the on-screen display circuit 1
7

Therefore, in this case, the recording circuit 16 records only the video signal S2 on the recording medium. Further, the on-screen display circuit 17 sends the reproduced video signal S6, which is the reproduced video signal S2, to the visual finder 23 and causes the visual finder 23 to display an image based on the reproduced video signal S6.

As a result, when the rotation angle detection unit 18 detects the rotation angle of the camera-integrated VTR 10, the video recording unit 15 together with the rotation angle data D1 corresponding to the rotation angle of the camera-integrated VTR 10 together with the rotation angle data. The video signal S2 corresponding to D1 is recorded in the recording circuit 16 and only the video signal S2 is recorded in the recording circuit 16 when the rotation angle of the camera-integrated VTR 10 is not detected.

(1-2) Rotation Angle Detector Here, as shown in FIG. 3, the rotation angle automatic detector 20 actually has a predetermined volume of an opaque predetermined liquid which does not transmit the light emitted from the light emitting diode. The inner ring portion 31 having a ring shape enclosed so as to have the bubbles 30 of
It is formed so as to be wrapped from the outside by an outer ring portion 32 having a ring shape having a concave cross-sectional shape. Further, the outer ring portion 32 has one surface 3 of the inner ring portion 31.
A plurality of light emitting diodes 33 are provided inside the surface facing 1A, and a photo sensor 34 is provided inside the surface facing the other surface 31B of the inner ring portion 31 so as to face each light emitting diode 33. In this case, the outer ring portion 32 is provided with the light emitting diode 33 and the photosensor 34 which are opposed to each other, so that the bubbles 3 in the inner ring portion 31 are
For example, it is possible to detect a position along the circumference of 0 which is divided into 16 equal parts.

As a result, in the automatic rotation angle detector 20, the emitted light LA2 is emitted from each of the light emitting diodes 33, and the emitted light LA2 is transmitted through the bubbles 30 of the inner ring portion 31.
Are detected by the photo sensors 34 facing each other, and the signals obtained by the respective photo sensors 34 are sent to the microprocessor 21 (not shown). Thus, the microprocessor 21 is the rotation angle automatic detector 20.
Of the signal obtained by each photo sensor 34 of the comparator or analog / digital conversion circuit (hereinafter referred to as A
A signal is processed by a (/ D conversion circuit) and the position of the bubble 30 in the automatic rotation angle detector 20 is detected.

Further, as shown in FIG. 4, the automatic rotation angle detector 20 includes a lens 11 in the camera-integrated VTR 10.
The circular surface 20A is fixed and arranged so as to be parallel to the one surface 13A of the imager 13 arranged at one end of the. Therefore, when the camera-integrated VTR 10 rotates, the rotation angle automatic detector 20 rotates in accordance with the rotation of the imager 13 that also rotates. As a result, in the rotation angle automatic detector 20, since the bubbles 30 of the inner ring portion 31 are always located in the direction opposite to the gravity direction, the rotation angle with respect to the imager 13 (that is, the rotation angle of the camera-integrated VTR 10 rotated by the user). ) Can be detected.

On the other hand, as shown in FIG. 5, the rotation angle manual detector 22 is a rotary encoder switch for detecting a direction radially divided into, for example, 16 equal parts based on one point at one end of the view finder 23. In this case, when the camera-integrated VTR 10 is rotated, the rotation angle manual detector 22 allows the user to rotate and position the rotary encoder switch so that the rotary encoder switch faces the direction of gravity, for example. Is detected as the rotation angle specified by the user.

(1-3) Structure of Video Reproducing Unit On the other hand, FIG. 6 shows a video reproducing unit 40 corresponding to the camera-integrated VTR 10 shown in FIG. 1, and the reproducing circuit 41 responds to a reproducing operation input by the user. To reproduce the video signal S2 and the rotation angle data D1 recorded on the recording medium 16,
The reproduced video signal S2 is sent to the A / D conversion circuit 42. The A / D conversion circuit 42 converts the video signal S2 into digital video data D2 and sends it to the writing circuit 43. Further, the reproducing circuit 41 sends the rotation angle data D1 corresponding to the video signal S2 to the writing circuit 43.

In the writing circuit 43, the number of pixels in one field of the image based on the image data D2 is, for example, 350 dots in the horizontal direction,
In the case of 262 dots vertically, each pixel position (0,0)… (0,261),
The rotation angle θ (φ to 2π radians) is calculated from the rotation angle data D1 for the pixel position (y, x) representing (1,0) ... (349,261) and the following equation (1) is obtained.

[Equation 1] Each pixel position (X, Y) rotationally converted based on is obtained, and the rotated video data D3 based on each pixel position (X, Y) is generated. Here, A and B indicate the amounts of parallel movement in the X-axis direction and the Y-axis direction due to the rotation of each pixel position. In addition to this, the writing circuit 43 generates an address corresponding to each pixel position (X, Y) and generates an address signal S7 based on the address.

Thus, the writing circuit 43 controls the switching circuits 44 and 45 so as to prevent the rotational image data D3 being read from being insufficient due to the reading of the rotational image data D3 being written. In the prepared field memories 46 and 47, the rotation image data D3 for each line of one field and the address signal S7 corresponding to the rotation image data D3 are alternately written. Thus, the writing circuit 43 can rotate the image based on the recorded image signal S2 based on the rotation angle data D1 and rotate the image according to the rotation angle of the camera-integrated VTR 10.

Incidentally, the field memories 46 and 47 are
If the number of pixels in one field of the image based on the rotated image data D3 is, for example, 350 dots in the horizontal direction and 262 dots in the vertical direction, the length of one field per one field memory is more than 440 dots in the horizontal direction and 440 dots in the vertical direction. It has a writing capacity.

Further, the writing circuit 43 uses the rotated video data D
3 and the address signal S7 to the field memories 46 and 4
When writing to 7 alternately, switching control is performed so that the switching circuits 48 and 49 are connected to the field memory 47 when the switching circuits 44 and 45 are connected to the field memory 46, and the switching circuits 44 and 45 are connected to the field memory 4.
When it is connected to 7, the switching circuits 48 and 49 are controlled to be connected to the field memory 46.

As a result, the read circuit 50 sends the address search signal S8 to the field memory 47 when the write circuit 43 is writing the rotary video data D3 and the address signal S7 in the field memory 46, and the written address signal. The rotation video data D3 corresponding to the address is read from the field memory 47 by referring to the address based on S7. Similarly, the read circuit 50 sends an address search signal S8 to the field memory 46 when the write circuit 43 is writing the rotary video data D3 and the address signal S7 to the field memory 47, and outputs the address based on the written address signal S7. With reference to, the rotation video data D3 corresponding to the address is read from the field memory 46.

As a result, the read circuit 50 prevents the read out rotation image data D3 from being insufficient by reading out the rotation image data D3 in the middle of writing, and surely reads out all the rotation image data. In addition, the reading circuit 50 uses the digital / analog conversion circuit 51 (hereinafter,
This is sent to the D / A conversion circuit 51). D / A
The conversion circuit 51 converts the rotation video data D3 into the analog rotation video signal S9, and the rotation video signal S9 has a number of lines corresponding to the number of lines of one field of the video reproduced by the video reproduction unit 40. 52.

As a result, even when the camera-integrated VTR 10 is rotated and an object is imaged on the monitor 52, the viewfinder 23 is displayed when the camera-integrated VTR 10 is imaged.
The image can be displayed in the display state of the image displayed in. Further, in the video reproduction unit 40, when the rotation angle detection unit 18 of the video recording unit 15 is in the off state, the reproduction circuit 41 reproduces only the video signal S2 and sends the reproduced video signal S2 to the A / D conversion circuit 42. To do. The A / D conversion circuit 42 converts the video signal S2 into digital video data D2 and sends it to the writing circuit 43.

The writing circuit 43 generates an address corresponding to each pixel position of the video based on the video data D2 and generates an address signal S7 based on the address. As a result, the writing circuit 43 controls the switching circuits 44 and 45 to switch and writes the image data D2 for each line of one field and the address signal S7 corresponding to the image data D2 alternately in the field memories 46 and 47.

The read circuit 50 sends out the address search signal S8 to the field memory 46 or 47 on the side where the sequential writing is completed, refers to the address based on the written address signal S7, and refers to the image corresponding to the address. The data D2 is read. In addition to this, the read circuit 50
The sequentially read video data D2 is sent to the D / A conversion circuit 51. The D / A conversion circuit 51 converts the video data D2 into an analog video signal S2 and sends it to the monitor 52. As a result, the monitor 52 is displayed on the screen shown in FIGS.
As shown in, the image in a state rotated according to the rotation angle of the camera-integrated VTR 10 is displayed with respect to the display state of the image displayed on the viewfinder 23 when the camera-integrated VTR 10 is imaged.

(1-4) Operation of the First Embodiment In the above configuration, in the video recording unit 15, the video signal S2 based on the imaged subject is detected by the rotation angle automatic detector 20 or the automatic rotation angle detector 20 according to the video signal S2. Rotation angle manual detector 2
It is recorded in the recording circuit 16 together with the rotation angle data D1 based on the rotation angle of the camera-integrated VTR 10 detected by 2. In this case, since the image based on the image signal S2 is displayed on the viewfinder 23, an arrow a indicating the rotation direction of the camera-integrated VTR 10 detected by the rotation angle automatic detector 20 or the rotation angle manual detector 22 is displayed.
The user can confirm whether or not the direction of the arrow a and the rotation direction of the image to be displayed on the monitor 52 match.

On the other hand, in the video reproducing section 40, the recording circuit 1
When the video signal S2 recorded in 6 is reproduced, the video signal S2 reproduced by the reproduction circuit 41 according to the reproduction operation input by the user is converted into the video data D2 through the A / D conversion circuit 42 and written. The rotation angle data D1 transmitted to the circuit 43 and reproduced by the reproduction circuit 41.
Is sent to the writing circuit 43. As a result, the video data D2 is rotated by the writing circuit 43 based on the rotation angle data D1 and is generated as rotated video data D3 based on the video subjected to the rotation processing. This rotation image data D
3 is converted into a rotation video signal S9 via the D / A conversion circuit 51 and sent to the monitor 52. This allows the monitor 5
On the display 2, the image based on the rotation image signal S9 is displayed in the display state of the image displayed on the viewfinder 23 when the camera-integrated VTR 10 is imaged.

Accordingly, the video recording unit 15 and the video reproducing unit 40
Even when the camera-integrated VTR 10 is rotated to capture an image of a subject, the camera-integrated VTR 10 records and reproduces a video signal S2 based on the imaged subject, and displays the image displayed on the viewfinder 23 at the time of imaging. Since an image can be displayed on the monitor 52 in the same display state as described above, a left-handed user can hold and use the left hand even when configured to assume a right-handed user.

(1-5) Effects of the First Embodiment According to the above configuration, the rotation angle detected by the rotation angle automatic detector 20 or the rotation angle manual detector 22 is converted into the rotation angle data D1 and imaged. The video signal S2 based on the subject is recorded in the recording circuit 16, and at the time of reproduction, the video based on the video data D2 is rotated by the writing circuit 43 based on the rotation angle data D1 and the rotary video data D3 based on the rotated image is processed. By the generation, it is possible to display on the monitor 52 an image in the same display state as the image displayed on the viewfinder 23 when the camera-integrated VTR 10 is imaged, thus improving the usability of the imaging device. The obtained video recording device, video reproducing device, and video recording / reproducing device can be realized.

(2) Second Embodiment (2-1) Configuration of Video Recording Unit FIG. 8 shows a camera-integrated VTR 60 according to the second embodiment, which is an object (not shown) obtained through a lens 61. The image pickup light LA3 of (1) is received by the imager 62. The imager 62 generates an imager signal S10 based on the imaging light LA3 and sends it to the camera signal processing circuit 63. The camera signal processing circuit 63 generates the video signal S11 based on the imager signal S10 and sends it to the switching circuit 66 of the video recording unit 65.

The rotation angle detector 67 of the video recorder 65 is
The rotation angle of the camera-integrated VTR 60 is detected, and the control signal S1 is detected according to the detection of the rotation angle.
2 is sent to the switching circuit 66. As a result, the switching circuit 66 is switching-controlled by the rotation angle detection unit 67, and when the rotation angle detection unit 67 detects the rotation angle, the switch is connected to the contact 66A, and the rotation angle detection unit 67 does not detect the rotation angle. In the off state, the switch is connected to the contact 66B.

In this case, the switching circuit 68 is the switching circuit 6
The switching circuit 6 operates in synchronization with the switching operation of the switching circuit 6
When switch No. 6 is connected to contact 66A, switch is connected to contact 68A. Further, the switching circuit 68, when the switch of the switching circuit 66 is connected to the contact 66B,
Connect the switch to contact 68B.

As a result, the camera signal processing circuit 63 switches the video signal S11 to the switching circuit 66 when the rotation angle detector 67 detects the rotation angle of the camera-integrated VTR 60.
To the read control circuit unit 69 via. The read control circuit unit 69 converts the video signal S11 into digital video data D10 via the A / D conversion circuit 70 and writes the video data D10 in the memory 71.
