  • Patent number: 10375270
    Abstract: Provided is a signal processing apparatus that enables an image reading apparatus to perform higher speed processing of reading a document image. A signal processing unit is configured to convert six analog image signals obtained from a line sensor into six first signals, each of which is a 10-bit digital image signal, respectively, and to write the six first signals into a RAM at a first speed that is the same as a frequency of the analog image signals. The signal processing unit is configured to cause a serialization unit to read out from the RAM the six first signals as four second signals, each of which is a 10-bit digital image signal, at a second speed higher than the first speed, respectively, and to serialize the four second signals to generate six 7-bit serial signals.
