Abstract

PURPOSE: To automatically print the still image of a desired scene on a video recorded in a magnetic tape. CONSTITUTION: At the time of recording, the printing designation signal synthesis circuits 191 and 190 of a camcoder 100 add printing designation signals to the video signal of the scene which is printed later and a control signal corresponding to the video signal. At the time of reproducing, the printing video detection circuit 140 of the camcoder 100 detects a printing video recording period. When a printing video detection circuit 141 detects a printing video against the recording period, a printing video detection signal is supplied to the synchronous printing control circuit 240 of a video printer 200 and a printing part 270 prints the reproduced video at that time. Since the detection control circuit 130 of the camcoder 100 controls a printing video detection operation in the camcoder 100 in synchronizing with printing, the still images of the desired video are automatically printed.

Detects the control signal to which the print designation signal is added to detect the print video recording section at high speed. Further, in accordance with the command signal from the video printer system control circuit 220, the camera-integrated VTR 102 reproduces this print video recording section, and the automatic print control circuit 242 of the video printer 202 detects the video signal to which the print designation data is added. , A print command signal is supplied to the video printer system control circuit 220, and the video printer system control circuit 220 supplies a control signal to each unit, and the video signal supplied from the camera-integrated VTR 102 at that time is printed as a still image. To be done.

During printing, a stop command signal is supplied from the reproduction control circuit 231 of the video printer 202 to the synchronous reproduction control circuit 132 of the camera-integrated VTR 102, and the camera-integrated VTR 102 suspends reproduction. When the printing of one scene is completed, the reproduction control circuit 231 supplies the print image detection start signal to the video printer system control circuit 220, and again the camera-integrated VTR 102 is operated in accordance with the command signal of the video printer system control circuit 220. The magnetic tape 1 to which the print designation signal is added is fast-forwarded and rewound at high speed.

A series of these operations are performed from the start end to the end of the magnetic tape, and all the scenes designated to be printed are printed by the video printer 202 at the time of shooting by the camera-integrated VTR 102.

As a result, it is possible to print a still image of a desired video automatically and in a short time.

In the first to third embodiments, the camera-integrated VTR and the video printer constitute an automatic image printing apparatus. However, even when the stationary VTR and the video printer are constituted, it is completely impossible. It can be realized in the same way.

Further, in the first to third embodiments, the duty ratio of the normal control signal is 6: 4 and the duty ratio of the control signal to which the print designation signal is added is 7: 3, but there are two types. If the above control signals can be distinguished, no matter how the duty ratio is set, they can be realized in exactly the same manner.

Furthermore, in the first to third embodiments, only one control signal having a duty ratio different from the normal duty ratio is recorded between the control signals having the normal duty ratio, and the control signal is detected. Although the case has been described, detection is performed by continuously recording two or more control signals having a duty ratio different from the normal duty ratio between the control signals having the normal duty ratio. Also has exactly the same effect.

Further, in the first to third embodiments, the VITC standard is used as a method of adding the print designation signal to the video signal, and the digital data is added to the 16th and 18th vertical blanking periods of the video signal. However, even if the digital data is superposed on any of the 10th to 21H periods excluding the vertical synchronization portion of the vertical blanking period without using the VITC standard, the same effect can be obtained. .

During printing, the reproduction control means of the image printing apparatus supplies a detection stop signal to the detection control means of the magnetic recording / reproducing apparatus, and the detection control means suspends the detection of the print image in the magnetic recording / reproducing apparatus. When the printing of one scene is completed, the reproduction control means supplies the detection start signal to the detection control means, and the detection control means restarts the detection of the print image in the magnetic recording / reproducing apparatus.

Therefore, as in the case where an image is printed by the conventional magnetic recording / reproducing apparatus and the image output apparatus, the operator who is operating the image can check the video signal reproduced by the magnetic recording / reproducing apparatus on the television monitor. , It is possible to print all still images of the desired video automatically with one button operation without printing the scenes to be printed one by one. Furthermore, the playback control circuit in the image printing device prints. The detection operation of the print image in the magnetic recording / reproducing apparatus is controlled according to the state, so that the next print image can be detected immediately after the printing is finished, and the printing of the designated scene is completed in a shorter time. .

Further, according to the automatic image printing apparatus of the present invention, at the time of recording, the first and second magnetic recording / reproducing apparatus are provided for the video signal of the scene to be printed later and the control signal corresponding to this video signal. Each of the print designation signal recording means adds a print designation signal.

At the time of reproduction, the reproduction control means of the image printing apparatus controls the magnetic recording / reproducing apparatus for fast-forwarding, rewinding, reproducing, and stopping operations of the magnetic tape in synchronization with the detection and printing operation of the print image. The print image recording section detection means of the image printing apparatus detects the control signal to which the print designation signal is added to detect the print image recording section in which the image to be printed is recorded.
