Apparatus and method for generating time lapse image

A method of generating a time lapse image, the method comprising:

• determining a sampling interval of time lapse photographing over time based on a reference value acquired in real time while the time lapse photographing is performed;
• determining a window corresponding to a region of a full frame obtained from a photographing device, used for stabilizing frames, and having a size based on the sampling interval;
• sampling a plurality of input frames generated from an image signal provided by imaging circuitry of a photographing device at the sampling interval while the time lapse photographing is performed;
• stabilizing a plurality of frames selected by sampling the plurality of input frames, using data of a region corresponding to the window;
• compressing the plurality of selected frames at an output frame rate to generate a time lapse image file;
• and
• storing the time lapse image file.

A non-transitory computer-readable recording medium having recorded thereon computer program code for use in generating a time lapse image, which, when executed by a processor, causes the processor to perform operations comprising:

• determining a sampling interval of time lapse photographing over time based on a reference value acquired in real time while the time lapse photographing is performed;
• determining a window corresponding to a region of a full frame obtained from a photographing device used for stabilizing frames, and having a size based on the sampling interval;
• sampling a plurality of input frames generated from an image signal provided by imaging circuitry of a photographing device at the sampling interval while the time lapse photographing is performed;
• stabilizing a plurality of frames selected by sampling the plurality of input frames, using data of a region corresponding to the window;
• compressing the plurality of selected frames at an output frame rate to generate a time lapse image file;
• and
• storing the time lapse image file.
