Abstract
A still picture recording digital camera including a light quantity limiter for interrupting incident light to the camera; an image pickup unit including a pixel for converting the incident light to an electric pixel signal and outputting the pixel signal as a digital image signal; a signal processor for generating a digital image signal having a predetermined format; a recording unit for recording the digital image signal output from the image pickup unit or the signal processor; the light quantity limiter limiting the incident light quantity to a predetermined quantity and then interrupting the incident light; the image pickup unit outputting a dynamic picture digital image signal when the light quantity limiter is limiting the incident light quantity, and outputting a still picture image signal after the light quantity limiter has interrupted the incident light; and the signal processor performing different signal processing operations when the signal processor has received a digital image signal for a dynamic picture and a digital image signal for a still picture.
