PROBLEM TO BE SOLVED: To provide an electronic zoom device for generating a large-scaled static image in image size conversion at a fixed rate by using a conventional electronic zoom circuit for the video signal converter of a television or the like. SOLUTION: This electronic zoom device is provided with an image recording memory 1, display size memory 9, memory reading part 2 for reading images by each strip by strip-dividing an image recording memory 1 to a horizontal direction, electronic zoom coefficient calculating part 3, line memory part 6, line memory writing part 5, line memory reading part 7, memory writing part 8 for a display size memory 9, and coefficient offset indicating part 4 for outputting the offset value of a coefficient preliminarily calculated based on the final zoom coefficient of the strip to the electronic zoom coefficient calculating part 3. |
