The first screen read out from the image memory at the time of switching the images and at the time of starting the recording of the second image when the last screen of the first image is taken into the image memory in response to the stop signal of the recording or reproduction of the image. The timing signal generating means controls the switching means for switching and transmitting the image signal and the contents of the image memory at the start of the next recording so that the still image which is the last screen of the image is gradually switched by the second image. Thus, the recording unit connected to the output side of the switching means performs recording while switching from the last screen of the first image to the second image at the start of recording the second image. It is obtained by the.

Therefore, according to the present invention, by adding the image memory, the image capturing control means, the switching means, and the timing signal generating means, it is a still image when switching from the first image to the second image. The last screen of the first image is gradually switched by the second image, and it is possible to obtain an image recording apparatus having a simple wiper function.

In particular, according to the present invention, when the recording or reproduction is stopped, the entire last screen of the first image is fetched and stored in the image memory in response to the recording or reproduction stop signal. The switching means is switched by the timing signal generating means so that the still image, which is the last screen of the first image read out from the image memory at the start of recording the second image, can be gradually switched by the second image. Since the first image and the second image do not need to be supplied to the switching means in parallel, the wipe operation can be performed at the time of switching by supplying the image of one line.
