Patent ID: 8817171

Claim:
An imaging apparatus comprising: a flash unit for emitting light toward an object; an imaging unit for photographing the object to obtain an object image of the object, wherein the imaging unit obtains a first object image of the object with the flash unit emitting light, and obtains a second object image of the object with the flash unit emitting no light; a brightness obtaining unit for obtaining a brightness of the first object image and a brightness of the second object image; a brightness-difference obtaining unit for obtaining a brightness difference of the object between the brightness of the first object image and the brightness of the second object image obtained by the brightness obtaining unit; an object-distance obtaining unit for obtaining an object distance between the imaging unit and the object; a reference brightness-difference storing unit for storing a reference brightness-difference; a target brightness obtaining unit for obtaining a target brightness based on a value that is obtained from a formula that includes the brightness difference, the reference brightness, and the object distance; and an exposure-condition adjusting unit for adjusting exposure conditions for adjusting brightness of an image and under which the imaging unit photographs the object, based on the target brightness; wherein the target brightness obtaining unit obtains said value from the formula C=B×L 2 where C is said value, B is the brightness difference, and L is the object distance, and wherein the target brightness obtaining unit obtains the target brightness from the formula D=E×C/A where D is the target brightness, E is a predetermined number, C is said value, and A is the reference brightness-difference.
