The imaging unit 16 converts the blue signal (B), green signal (G), and red signal (R) signals for one field into A / D signals.
After the conversion, it is sent to the recording signal processing unit 17. The recording system signal processing unit 17 encodes the three primary color signals of B, G, and R and converts them into a luminance signal (Y) and a chrominance signal (C), and converts the luminance signal (Y) into an FM signal. The chrominance signal (C) is converted into a low frequency,

The memory 38 is composed of three memory sections which store digitized three primary color signals independently for each field, and write and read operations are performed under the control of the control section 39. The written signal is
In the single-frame print mode, the image data is directly read from the memory 38 and sent to the image processing unit 40. In the strobe mode, the image data is sent to the image processing unit 40 after being reduced in size by thinning out and reading. The image processing unit 40 performs color correction,
Image processing such as gradation correction and fitting synthesis is performed. The image processing of the embedding synthesis is performed in the strobe mode, and performs processing for arranging a plurality of reduced-size frames in a matrix. Can be arbitrarily set. In the single-frame print mode, interpolation processing is performed to convert the image into a frame image. The image-processed signal is written to the frame memory 41 under the control of the control unit 39.

The frame memory 41 is also composed of three memory units, and a read operation is performed under the control of the control unit 39. At the time of printing, only one of the three colors is read out line by line. The read signal is once written to the line memory 42 and then read out, and sent to the head drive unit 43. This head drive unit 4
Reference numeral 3 drives the thermal head 44 based on the signal for one line. As is well known, the thermal head 44 has a large number of heating elements arranged in a line in the main scanning direction, and heats the thermosensitive recording paper 45 to sequentially perform three-color surface recording. After the thermal recording of one color is performed, light fixing is performed by irradiation of an ultraviolet lamp (not shown) corresponding to the thermosensitive coloring layer of this color, and then the next color is thermally recorded. The thermosensitive recording paper 45 is a sheet-shaped recording paper provided with a thermosensitive coloring layer composed of cyan, magenta, and yellow.

The image processing section 40 sends a creation completion signal to the control section 39 when the creation of the multi-flash image is completed. The control section 39 sends a control signal to the external control output terminal 15 upon receiving the creation completion signal. This control signal is taken into the control unit 22 of the video printer 10 via the external control input terminal 14. This control signal is a signal for notifying that the capture of the still strobe image has been completed on the video printer 10 side. When this signal is input, the next frame inserted into the multi-strobe image by the control unit 22 is displayed. In order to detect the position of the recorded video tape, control is performed such that a strobe print completion signal is recorded on the 8-mm video tape 26.

The control unit 39 of the video printer 10 is provided with a strobe button 39b in addition to the print button 39a. The strobe button 39b is used to execute the creation of a multi-strobe image by one operation,
At the time of the operation after the first time, the creation of the subsequent multi-flash image is executed. When the strobe button 39b is operated, the three-color multi-strobe image signals written in the frame memory 41 are simultaneously read out, and the external video output terminal 4 is output via the D / A converter 46 and the encoder 47.
8 to display a multi-strobe image on a monitor 49 connected to an external video output terminal 48.

The control section 39 sends a search signal to the external control output terminal 15 when the second or subsequent operation of the strobe button 39b is performed. This search signal
The video data is captured by the control unit 22 via the external control input terminal 14 of the video camera recorder 12. When the control unit 22 of the video camera recorder 12 receives the search signal, it controls the tape traveling mechanism 21, the servo 20, and the like to search for the strobe print completion signal recorded on the 8 mm video tape 26, and the video signal of the next frame Is controlled to be played.

FIG. 2 shows a tape format of an 8 mm video tape. Since the azimuth recording method is used in the 8 mm video standard, helical scanning is performed during recording and reproduction. The video signal is a video track (video area)
The audio signal is frequency-multiplexed and recorded on a PCM audio track 51 provided by extending the video track 50. The PCM audio track 51 is an area independent of the video track 50, and a video subcode track 53 is added between them. The video subcode track 53 records the above-described strobe print completion signal.

Next, the operation of the above configuration will be described.
When recording, the operation unit 23 of the video camera recorder 12 is operated to enter a recording standby state. As a result, the luminance signal (Y) that has been subjected to the encoder processing among the video signals captured by the imaging unit 16 through the imaging lens 54 is transmitted to the liquid crystal finder 55. The photographer performs framing while looking at the viewfinder 55, for example, toward a subject who is performing a golf swing, and operates the operation unit 23 to start recording.

The imaging unit 16 converts the signals of the three colors B, G, and R into digital signals, and sends the signals to the recording signal processing unit 17. The recording system signal processing unit 17 encodes the three primary color signals of B, G, and R to convert them into a luminance signal (Y) and a chrominance signal (C), and converts the luminance signal (Y) into an FM signal and a color signal. The signal (C) is converted into a low frequency, and both are converted to a video track 5
0 is multiplex-recorded.

When printing is performed by the video printer 10 after recording, the external video input / output terminals 11 and 13 and the external control input / output terminals 14 and 15 of the video camera recorder 12 and the video printer 10 are connected to each other. A monitor 49 is connected to the external video output terminal 48 of the video printer 10.

Next, by operating the operation unit 23 of the video camera recorder 12, the previously recorded images are reproduced one by one as shown in FIG. As a result, the video signals picked up by the R / P heads 24 and 25 are subjected to the encoding processing of the luminance signal (Y) and the chrominance signal (C) by the reproduction system signal processing unit 19, and are output as NTSC signals to the external video output terminal 13.

One line is read out for each primary color and sent to the line memory 42. The signal written in the line memory 42 is transmitted to the control unit 3
9 and is sent to the head drive unit 43. The head driving unit 43 drives the thermal head 44 based on signals for one line.

In driving the thermal head 44, first, when a yellow signal for one line is supplied, the yellow thermosensitive coloring layer of the color thermosensitive recording paper 45 is heated to record a yellow image line by line. The portion on which the yellow image is recorded is irradiated with ultraviolet light of a predetermined wavelength by a yellow ultraviolet lamp and is optically fixed.

After the light fixing of the yellow image recording, the color thermosensitive recording paper 45 faces the thermal head 44, and the thermal recording of the magenta image is started. As a result, the magenta thermosensitive coloring layer of the color thermosensitive recording paper 45 is thermally recorded line by line, and after the recording is completed, it is optically fixed by a magenta ultraviolet lamp. Finally, the cyan thermosensitive coloring layer of the color thermosensitive recording paper 45 is thermally recorded one line at a time by the cyan signal, and after the recording is completed, it is light-fixed by a cyan ultraviolet lamp.

When the three-color-sequential recording is completed, the color thermosensitive recording material 45 is sent out and discharged as a hard copy 45a from the discharge port 53 onto the tray 54. In the hard copy 45a, one continuous frame is arranged in a 3 × 3 matrix.

Next, in order to perform the next strobe printing, the strobe button 39b of the video printer 10 is again operated.

This search signal is taken into the control unit 22 via the external control input terminal 14 of the video camera recorder 12. The control unit 22 that has received the search signal operates the tape traveling mechanism 21, the servo 20, and the like, and operates the video subcode track 53.
Is searched for the strobe print completion signal recorded in the video track 50, and reproduction is performed from the video track 50 in which the strobe print completion signal is written. At this time,
The previously recorded strobe print completion signal may be deleted.

The reproduced signal is captured by the video printer 10 as described above, and the image of each frame shown in FIG. 4A is sequentially captured by the memory 38. The multi-flash image shown in () is created and written in the frame memory 41. Since this image is displayed on the monitor 49, after confirming this display,
The print button 39a is operated.

The multi-flash image written in the frame memory 41 by operating the print button 39a is
The image is recorded on the color thermosensitive recording material 45 by the thermal head 44, and is discharged as a hard copy 45 a from the discharge port 53 onto the tray 54. In the hard copy 45a, subsequent images recorded by the above-described strobe printing are continuously arranged in a 3 × 3 matrix.

In the case where a well-known S terminal is provided, since the luminance vibration (Y) and the chrominance signal (C) are already input separately, they are directly input to the decoder 36.

Further, in the above embodiment, the video printer for recording an image on the color thermosensitive recording paper 45 on which the thermosensitive coloring layer is laminated has been described. However, the present invention is not limited to this. A sublimation type thermal transfer recording type thermal printer may be used. Also, the line printer has been described, but the present invention can also be applied to a serial printer.
