PROBLEM TO BE SOLVED: To provide an image recorder that applies compression coding to a dynamic image, records the compression-coded data onto a recording medium and also generates a reduced image. SOLUTION: An image signal photographed by an image pickup device 1 is converted into a digital signal, a compressor 3 compresses the digital image signal, and a writer 4 records a coded bit stream to a recording medium 5. At the same time as compression coding and recording processing are applied to the received image, a compression controller 6 accesses a frame memory in the compressor 3, generates a reduced image from the received image extracted at an interval of a prescribed frame number from the start of photographing and stores the generated reduced image to a memory area reserved in the frame memory. At the end of photographing, the generated reduced image is compression-coded. The recording medium 5 records the reduced image data that are compression-coded. Generation, coding and recording processing of the reduced image are conducted automatically.
