Is formed on the opposite side of the finder liquid crystal panel 6 with the lens 16 interposed therebetween, and an inverted enlarged real image is formed at a position BX2 away from the lens 16 by b2.

Next, the system configuration and operation of the video recorder 10 having the print function described above will be described.

First, as shown in FIG. 9, the system includes a CPU 21 for controlling the whole system, a camera circuit 22 and a video recorder circuit 23 of a video recorder, a memory 24 for recording an image to be printed, and an image stored in the memory 24 for the CPU 21. Still image switch 1 for instructing recording
2, a print switch 13 for instructing the CPU 21 to start a print operation, a direct-view liquid crystal panel 4 for displaying an image being shot or a reproduced image, a direct-view liquid crystal panel signal processing circuit 25 for driving the direct-view liquid crystal panel 4, A backlight 26 for illuminating the direct-view liquid crystal panel 4, an inverter circuit 27 for driving the backlight 26, a finder liquid crystal panel 6, a finder liquid crystal panel signal processing circuit 28 for driving the finder liquid crystal panel 6, and a finder liquid crystal panel 6. , And an inverter circuit 29 for driving the backlight 8.

Next, the operation will be described. First, a signal at the time of photographing with a camera or recording and reproduction of a video recorder is passed through a video recorder circuit 23 as a display signal to a liquid crystal panel signal processing circuit 25 for direct viewing, and It is supplied to a finder liquid crystal panel signal processing circuit 28. By pressing the still image switch 12 with the image to be printed, the CPU 21 detects this and controls the video recorder circuit 23, and the image at that time is taken into the memory 24. After that, the image recorded in the memory 24 is read out and is applied to the direct-view liquid crystal panel 4 and the finder liquid crystal panel 6 as a still image signal. At this time, the backlight 26 of the direct-view liquid crystal panel 4
Is turned on, while the inverter circuit 27 for driving
The inverter circuit 29 that drives the backlight 8 of the finder liquid crystal panel 6 is in a stopped state.

When the print switch 13 is depressed in this state, the CPU 21 detects this and activates the inverter circuit 29 for a time corresponding to the sensitivity of the film 15 mounted thereon, and is displayed on the finder liquid crystal panel 6. The still image is exposed on the film 15. After the above operation is completed, the photographed film 15 is processed according to its type. For example, if the film is an instant type film, it is discharged and developed, and if it is a normal 35 mm film, it is wound up, and the printing operation of the still image is completed.

In the above-described example, a signal is stored in the memory 24 and then supplied to the finder liquid crystal panel signal processing circuit 28 in order to create a still image, and the still image is displayed. It is also possible to adopt a configuration in which the video recorder is provided with a still image playback function, the video recorder is set to a still image playback state for an image to be printed, and the image is printed on the film 15 by activating the inverter circuit 29 for a predetermined exposure time. It is.
