Read-out mode changeable digital photographing apparatus and method of controlling the same

A non-transitory computer-readable recording medium having recorded thereon a program, which, when executed by a computer, performs a method comprising:

• capturing a moving image having a predetermined frame rate in a first read-out mode;
• estimating a brightness of surroundings, and then determining a shutter speed of a frame to be currently captured, based on the estimated brightness of the surroundings;
• determining whether or not an exposure time that is dependent on the shutter speed is longer than a predetermined time period;
• and
• changing the first read-out mode to a second read-out mode that has a shorter read-out time than the first read-out mode when the exposure time is longer than the predetermined time period.

A method of controlling a digital photographing apparatus using a plurality of image sensor read-out modes to capture frames of a moving image, comprising:

• determining a shutter speed and corresponding exposure time to capture a frame;
• determining a sum total of the exposure time and a read-out time of a current read-out mode;
• changing the read-out mode when the sum total is determined to exceed a frame time of a predetermined frame rate such that the frame may be captured within the frame time of the predetermined frame rate using the determined shutter speed;
• and
• capturing the frame.
