## Abstract

An image processing apparatus includes an imaging lens, an area image sensor having solid-state imaging elements arranged in a planar manner, and an imaging device for converting an image of an imaging object read by the area image sensor into image information. The imaging device is switchable between an electronic camera function mode and image scanner function mode. When the device is switched into the electronic camera function mode, the image information for one frame is outputted, whereas when the imaging device is switched into the image scanner function mode, the image information derived when an object to be read is manually scanned by the area image sensor in response to a moving amount of the manual scanning operation is outputted as continuous image information. Image information may thus be acquired over a wide range by employing a single image information processing apparatus.
