Apparatus and method for storing moving image portions

A portable electronic device comprising:

• an image sensor;
• a display;
• a first memory;
• a second memory;
• and
• at least one processor configured to:
• control the image sensor to obtain a plurality of frames of motion picture,
• store the plurality of frames in the first memory, temporarily,
• control the display to display live-view images based on the plurality of frames,
• in response to receiving a first user input, store a first motion picture in the second memory, the first motion picture generated based on first frames and second frames, wherein the first frames correspond to at least a portion of the plurality of frames, obtained within a first predetermined period prior to a time that the first user input is received, stored in the first memory, wherein the second frames correspond to frames, obtained by the image sensor within a second predetermined period after the time the first user input is received, and
• in response to receiving a second user input, store a second motion picture in the second memory, the second motion picture generated based on third frames, wherein the third frames correspond to frames, obtained by the image sensor within a third predetermined period after a time the second user input is received, wherein the second user input is received within the second predetermined period.
