Patent ID: 7268810

Claim:
A digital camera which obtains image data representing an object by forming an image of the object on a solid imaging device comprising a set of a plurality of two-dimensionally arranged unit light receiving elements, the digital camera controlling exposure according to a set sensitivity, the digital camera comprising: a sensitivity setting operation member which sets sensitivity; an image size setting operation member which sets a recording image size; a pixel mixing section which operates if the sensitivity setting operation member is operated to set a predetermined sensitivity, to execute a pixel mixing process on a plurality of pieces of luminance information obtained from the plurality of unit light receiving elements constituting the solid imaging device, the pixel mixing process comprising integrating the plurality of pieces of luminance information together so that one new piece of luminance information is formed of every predetermined number of pieces of luminance information obtained from a predetermined number of adjacent unit light receiving elements, the pixel mixing section thus reducing a recordable image size to a predetermined high-sensitivity-compatible image size to realize the predetermined high sensitivity; an image size setting section which sets the recording image size according to an operation of the image size setting operation member and if a recording image size larger than the high-sensitivity-compatible image size has previously been set, changes the recording image size to the high-sensitivity-compatible image size in response to setting of the predetermined high sensitivity carried out by operating the high-sensitivity setting operation member; and a display section which indicates that the recording image size has been changed to the high-sensitivity-compatible image size if the image size setting section changes the recording image size to the high-sensitivity-compatible image size in response to the setting of the predetermined high sensitivity carried out by operating the sensitivity setting operation member.
