When using a digital still camera to sense and capture an image of a medium with a bar code being recorded thereon for indication of information to be input to the digital still camera (such as information indicative of photographing conditions and/or information representing processing conditions of image processing), judgment is done to determine whether a region equivalent to the bar code is present within an image, and then a region equivalent to the bar code is extracted for analyzation of coded information as indicated by such bar code; if no contradiction is found in the coded information then let it be stored in a storage or "memory" region pursuant to the kind of such coded information. And the information thus stored will be used to perform setting of image pickup conditions and/or setup of image processing condition.
