1. 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.

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.

15. 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. - View Dependent Claims (16, 17, 18, 19, 20)
