Patent ID: 8223267

Claim:
A signal processing apparatus comprising: a first image generating unit that generates an image; a second image generating unit that generates an image different from the image generated by the first image generating unit; a first selecting unit that selects at least one of the first image generating unit and the second image generating unit and outputs an image from the selected one; an image signal processing unit that performs signal processing on the image outputted from the first selecting unit and outputs the processed image; a second selecting unit that selects one of the first selecting unit and the image signal processing unit and outputs an image from the selected one; a storing unit that stores information on operations of the second image generating unit and the image signal processing unit; and a third selecting unit that selects at least one of the second image generating unit and the image signal processing unit and connects the selected one to the storing unit, whereby the storing unit is shared between the second image generating unit and the image signal processing unit.
