Abstract: An image recording and reproducing apparatus receives a string of image data consisting of image data of a plurality of frames. An image encoding section sequentially calculates difference image data for pixels of adjacent image data of the received image data. At least one reference image data among the string of image data and respective difference image data calculated by the image encoding section are recorded by a recording unit. The image data read out from the recording unit is sequentially calculated with reference to the reference image data, and the string of image data is decoded.
