ABSTRACT:
An image processor is provided, which has the capability of detecting an object such as a human face from an image taken against the sun with high accuracy. An image signal provided from an image pickup unit is adjusted at an analog gain by an image adjuster. An out of the image adjuster is converted into a digital, and store in a memory. A feature of the object is extracted from this digital image data to detect an object area in the image. When the object area is not detected, an analog-gain controller sends that the image signal provided from the image pickup unit is adjusted at a different analog gain. Thus, the treatment of detecting the object area is repeated at different analog gains.
