Abstract
The present invention provides an image sensing apparatus in which an AD converter 8 has a quantization bit count that can be modified, thereby reducing the power consumption of a digital signal processing circuit 9. Here, the processing bit count of the digital signal processing circuit 9 is made identical to the AD bit count modified. This configuration enables to improve the image quality and reduce the power consumption in the entire system.
Claims11
An image sensing apparatus comprising:
- an image quality mode setting block for setting one of a plurality of image quality modes;
- a solid state image sensing element for converting an optical image into an electric analog signal;
- and
- an AD conversion block for converting the analog signal output from the solid state image sensing element, into a digital signal with a quantization bit count corresponding to an image quality mode set by the image quality mode selection block.
