PURPOSE:To match a processed image to the variable power rate of the image of an analog optical system by increasing the deviation of variable power rate lambda-times when an image read by an image sensor is converted to an electric signal to perform image processing. CONSTITUTION:A colored image, for example, a red image of an original is formed mainly on the first photosensitive body 10 by a transmitted luminous flux out of luminous fluxes divided by a half mirror 6, and a black image is formed mainly on the second photosensitive body 11 by the luminous flux reflected on the half mirror 6. When a focusing lens or the image sensor is moved, the variable power rate is not matched to that of the analog optical system though the image is focused on the image sensor. This deviation of variable power rate is increased lambda-times when the image read by the image sensor is converted to an electric signal to perform image processing, thereby matching the processed image to the variable power rate of the image of the analog optical system. |
