Patent ID: 7365888

Claim:
An image read apparatus comprising: a first sensor including a plurality of light receiving devices arranged in a main scanning direction; a second sensor which includes a plurality of light receiving devices arranged in the main scanning direction and which is disposed at a predetermined distance from the first sensor in a sub-scanning direction; a first output unit that outputs a pixel signal obtained from each light receiving device of the first sensor in an arrangement order of the light receiving devices; a second output unit that outputs pixel signals obtained from even-numbered light receiving devices in the light receiving devices constituting the second sensor in the arrangement order of the light receiving devices; a third output unit that outputs the pixel signals obtained from odd-numbered light receiving devices in the light receiving devices constituting the second sensor in the arrangement order of the light receiving devices; a conversion unit that converts the pixel signals from the respective output units into pixel data which are digital signals; and a pixel data storage unit that stores the pixel data outputted from the conversion unit, the image read apparatus further comprising: an information storage unit in which information with respect to the number of pixels outputted per scanning by each output unit is stored for each output; and a pixel data storage limiting unit that limits the pixel data to be stored in the pixel data storage unit based on the information stored in the information storage unit.
