Abstract:
An original image is read as an aggregate of a plurality of pixels in which adjacent pixels have different colors (R, G, and B) in a main scanning direction and in a sub-scanning direction, and the read pixels of the respective colors are stored in a line memory in association with information on relative positions of the pixels with respect to another pixel. Then, the stored pixels are sorted so that pixels having the same color are adjacent to each other, and an abnormal pixel (dust) not present in the original image is detected based on the state of the sorted pixels. With this, the dust not present in the original image is detected without increasing the cost, and the dust is corrected without forming a conspicuous trace of correction.

Claim (Index 14):
An image reading apparatus, comprising:\n a sensor to receive reflected light from an object, the sensor including first and second line sensors,\n the first line sensor including a first plurality of light receiving elements, being arranged in a first direction, which include a light receiving element receiving light of a first color and a light receiving element receiving light of a second color that is different from the first color \n the second line sensor including a second plurality of light receiving elements, being arranged in the first direction, which include a light receiving element receiving light of the first color and a light receiving element receiving light of the second color, and \n the first line sensor and the second line sensor being arranged at a predetermined interval in a second direction orthogonal to the first direction; \n a processor; and a memory storing instructions which, when executed by the processor, cause the processor: to detect an abnormal pixel of the first color based on:\n image data of a first light receiving element receiving light of the first color which is disposed at a first position in the first direction in the first line sensor; and \n image data of a second light receiving element receiving light of the first color which is disposed at a second position in the first direction in the second line sensor, the second position being a position which is different from the first position in the first direction, and \n to detect an abnormal pixel of the second color based on:\n image data of a third light receiving element receiving light of the second color which is disposed at a third position in the first direction in the first line sensor; and \n image data of a fourth light receiving element receiving light of the second color which is disposed at a fourth position in the first direction in the second line sensor, the fourth position being a position which is different from the third position in the first direction.
