Image processing apparatus, image processing method, and program product

An image processing apparatus comprising:

• an imaging device;
• a main memory that stores motion picture data acquired by the imaging device;
• a motion picture compressing unit that compresses the motion picture data stored in the main memory;
• a still image frame acquiring unit that acquires a still image frame at arbitrary timing from the motion picture data acquired by the imaging device;
• a line memory that stores still image data that is a part of the still image frame acquired by the still image frame acquiring unit, a size of the line memory is less than a size of the still image frame;
• and
• a still image compressing unit that performs a compression process of the still image data stored in the line memory,
• wherein the still image compressing unit compresses the still image data in real time in parallel with storage of the motion picture data into the main memory, and
• wherein the main memory stores the motion picture data and stores compressed data that is compressed in real time by the still image compressing unit.
