Abstract:
An image processing apparatus comprising:a photoelectric conversion area including a first light-receiving element array comprising a first plurality of light-receiving elements arranged in a main scanning direction, and a second light-receiving element array comprising a second plurality of light receiving elements arranged in the main scanning direction, said first and second light-receiving element arrays being arranged adjacent to each other in a sub-scanning direction; and a signal processing circuit adapted to effect a first resolution mode and a second resolution mode having a resolution lower than that of the first resolution mode, and to generate first and second resolution signals, wherein, in the first resolution mode, said signal processing circuit generates the first resolution signal from signals only from the first plurality of light-receiving elements, and in the second resolution mode, said signal processing circuit generates the second resolution signal from a sum of signals from the first and second plurality of light-receiving elements.
