Patent ID: 7589769

Claim:
A camera comprising: an image pick-up unit which accumulates electric charges corresponding to incident light, converts the accumulated electric charges into image data, and outputs the image data; a first pick-up control unit configured to obtain first image data output from the image pick-up unit under a condition where an incident light path of the image pick-up unit is opened; a second pick-up control unit configured to obtain second image data output from the image pick-up unit under a condition where the incident light path of the image pick-up unit is closed; an image correcting unit which corrects the first image data obtained by the first pick-up control unit based on the second image data obtained by the second pick-up control unit; a judging unit which judges whether the first image data need be corrected by the image correcting unit; and a controller configured to render the image correcting unit to execute correction of the first image data when the judging unit judges that the first image data need be corrected by the image correcting unit, wherein the judging unit judges whether the second image data need be obtained by the second image pick-up control unit; wherein the controller renders the second image pick-up control unit to obtain the second image data when the judging unit judges that the second image data need be obtained by the second image pick-up control unit; and wherein the camera further comprises a temperature detector which detects a temperature around the image pick-up unit, wherein the judging unit judges whether the first image data need be corrected by the image correcting unit based on the temperature detected by the temperature detector.
