Abstract
An image signal processor for reducing power consumption. The image signal processor is connected between a solid-state imaging device, which generates a first image signal, and an external device, and includes first and second regulators, a switch circuit, a signal processing circuit, and an output circuit. The first regulator generates a first voltage that is in accordance with an output level of the solid-state imaging device. The second regulator generates a second voltage that is in accordance with an input level of the external device. The switch circuit supplies the power supply voltage or the second voltage to the output circuit in accordance with the operating state of the imaging external device. The signal processing circuit operates with the first voltage and generates a second image signal. The output circuit provides the second image signal to the external device.
