SIGNAL PROCESSING CIRCUIT, IMAGING DEVICE, AND PROGRAM
First Claim
1. A signal processing circuit comprising:
- an image processing unit that performs, at an early stage, a process which is common to first image signals input using a predetermined number of signal lines in correspondence with first image sensors having a first pixel array and second image signals input using a number of signal lines different from the number of signal lines used to input the first image signals and commonly used to input the first image signals in correspondence with second image sensors having a second pixel array different from the first pixel array, and performs specific processes which are specific to the first image signals and the second image signals at a later stage;
a conversion unit that converts the second image signals subjected to the specific process according to a format of the first image signals; and
a selection unit that selects one of the first image signals subjected to the specific process and the converted second image signals and outputs the selected image signals using the predetermined number of signal lines.
