ABSTRACT:
A solid-state image sensor and a digital cameral capable of executing accurate image-shooting adjustment even in a low illumination environment. A charge coupled device type of image sensor includes red, green and blue pixel cells provided with color filter segments and control cells not provided with color filter segments. When a controller determines that the illumination of a scene to be picked up is short, a digital signal processor generates estimated luminance and contrast values for automatic exposure and automatic focus controls in accordance with the outputs of the control cells. An exposure value and the focal position of a lens are adjusted in accordance with those estimated values. The scene is shot in the form of a still picture in response to a shutter release signal.
