PHOTOELECTRIC TRANSDUCER, IMAGE READING DEVICE, IMAGE FORMING APPARATUS, AND IMAGE READING METHOD
First Claim
1. A photoelectric transducer comprising:
- a plurality of pixels arranged in one direction for each of colors of light to be received, and configured such that light is converted into an electrical signal in each of the plurality of pixels;
a parallel processor configured to perform parallel processing on a plurality of electrical signals obtained through conversion in the pixels in synchronization with a spread-spectrum clock for each of pixel groups, each of the pixel groups including a predetermined number of pixels; and
a corrector configured to correct an offset level of each of the plurality of electrical signals having undergone the parallel processing performed by the parallel processor, using one of values, each of the values being common within one of the pixel groups.
