Abstract
An image reading device includes an image reading device, a video memory for reading the read image and a device for controlling the reading frequency, when the video data recorded in the video memory are repeated read, so that the reading frequency will be equal to the scanning frequency of the television signals. The image read by the line sensor may be converted in this manner into video signals by a simplified operation.
