ABSTRACT:
A DSP calculates time integration of the light amount received by a CCD, using an input image. Determination is made regarding whether or not the light amount is equal to or smaller than a predetermined threshold. In a case that the light amount is equal to or smaller than the predetermined threshold, the DSP outputs a control signal to an AD converter for operation in the 8-bit mode. In a case that the light amount is greater than the threshold, the DSP outputs a control signal to the AD converter for operation in the 10-bit mode. The AD converter has a function of dynamic adjustment of conversion bits according to control from the DSP.
