[0007]

However, each of the video camera integrated video tape recorders shown in FIGS. 4, 5 and 6 has the following problems. That is, in the case of the video camera integrated video tape recorder having only the EVF shown in FIG. 4, it is difficult for a large number of people to enjoy the pattern because the EVF screen is small when the recorded screen is reproduced.

Further, in the case of the video camera integrated video tape recorder equipped with the OVF shown in FIGS. 5 and 6, the OVF 111 is usually used to confirm the subject.
The OVF 111 extracts a partial range of a captured image when elements such as digital zooming of a screen and wide television compatibility are added, and pixel data is interpolated or a predetermined upper and lower range is extracted in the range. Since signal processing such as cutting the range is performed, the image frame is different from the actual image pickup result, which makes it difficult to accurately image the subject in the desired range.

The present invention has been made in view of such a situation, and it is possible to reproduce and enjoy images recorded by a large number of people and to accurately capture a subject in a desired range. The purpose is to do so.
