Abstract
Provided is a method of controlling a digital photographing apparatus that performs exposure in response to a photographing command signal and captures an image. The method includes (a) capturing an image of at least a first field using a smaller amount of exposure than a reference amount of exposure; (b) capturing an image of at least a second field using a larger amount of exposure than the reference amount of exposure; and (c) synthesizing the images of the at least first and second fields.

A method of controlling a digital photographing apparatus that performs exposure in response to a photographing command signal and captures an image, the method comprising:
- (a) capturing an image of a first field using a first exposure;
- (b) capturing an image of a second field using a second exposure, wherein the level of the second exposure is different from the level of the first exposure;
- and
- (c) synthesizing the images of the first and second fields.
A method of controlling a digital photographing apparatus that performs exposure in response to a photographing command signal and captures an image, the method comprising:
- (a) capturing an image of a first field using a smaller exposure than a reference exposure;
- (b) capturing an image of a second field using a larger exposure than the reference exposure;
- (c) adjusting an average brightness of the image of the first field and an average brightness of the image of the second field;
- and
- (d) synthesizing the images of the first and second fields.
A digital photographing apparatus comprising:
- an optical system including an aperture;
- a photoelectric conversion unit in optical communication with the aperture for receiving a light reflected from a subject and creating an image signal according to the light;
- a processor linked with the aperture and the photoelectric conversion unit for controlling opening and closing of the aperture and for storing an image file based on the image signal;
- and
- a memory linked with the processor, wherein the memory stores at least one lookup table for increasing a brightness detectable range of the photoelectric conversion unit.
