By doing so, it is possible to confirm the content of the moving image reproduced on the video monitor 40 and to confirm the moving image captured by the imaging unit 23.

Further, as shown in FIG. 10A, instead of the thumbnail images, images such as characters indicating the characteristics of the moving images recorded on the optical disk 26 may be displayed. In addition, as shown in FIG. 10B, a moving image reproduced on the video monitor 40 together with an image such as a character indicating the feature of the moving image, or as shown in FIG. The moving image captured by the imaging unit 23 or FIG.
As shown in FIG. 0 (D), the moving image being reproduced and the moving image captured by the imaging unit 23 may be displayed on the video monitor 40.

Further, as shown in FIG. 11A, a plurality of moving images recorded on the optical disk 26 may be displayed instead of a plurality of thumbnail images. In addition to the moving image, as shown in FIG.
The moving image reproduced on the video monitor 40, or FIG.
1C, a moving image captured by the imaging unit 23, or a moving image reproduced on the video monitor 40 as illustrated in FIG. Moving images may be displayed.

In the video apparatus 1 of FIG. 1, the moving image picked up by the image pickup section 23 is recorded on the optical disk 26 and the recorded moving image is reproduced. Instead, the image recorded on the optical disk 26 may be reproduced by some processing beforehand as a reproducing apparatus.

Further, mechanical contacts can be used instead of the electronic contacts 28A and 28B of the image controller 28.

Further, an optical disk 26 is used as a recording medium.
However, a magnetic disk or a semiconductor disk may be used. Although the touch panel 5 is used as the instruction input unit, a mouse or the like may be used. Although the LCD 4 is used as the image display unit 30, the CRT (Cath
ode Ray Tube).

As a recording medium for providing a user with a computer program for performing the above-described processing,
In addition to recording media such as magnetic disks, CD-ROMs, and solid-state memories, communication media such as networks and satellites can be used.

[0070]

As described above, according to the image processing apparatus of the first aspect, the image information read by the reading means is not supplied to the display means while the image information is being output by the output means. Thus, while the image information is being output, it is possible to confirm the images that can be output and to select the images to be output.

According to the image processing method of the sixth aspect and the recording medium of the seventh aspect, while the image information is output in the output step, the image information read in the read step is stored in the read step. Since the information is not supplied to the display step, while the image information is being output, an image that can be output can be confirmed and an image to be output can be selected.
