Linear image sensor, image reading apparatus using the same, image reading method, and program for implementing the method |
摘要 |
A linear image sensor which has an enhanced image resolution, and requires reduced processing time, and is low in cost. A first line sensor has a plurality of light receiving elements linearly arranged at a predetermined pitch in a main scanning direction. A second line sensor has a plurality of light receiving elements linearly arranged at the predetermined pitch in the main scanning direction. The light receiving elements of the second line sensor are shifted from the light receiving elements of the first line sensor by half the predetermined pitch in the main scanning direction. The second line sensor has a length in the main scanning direction shorter than that of the first line sensor, and is arranged in parallel to the first line sensor and spaced from the first line sensor by a predetermined distance in a sub scanning direction perpendicular to the main scanning direction.
