Patent ID: 8681860

Claim:
An apparatus comprising: a compressing device for executing complete compression processing if subject-image data represents a subject image of a frame of a prescribed ordinal number from a reference frame, and for executing differential compression processing if subject-image data does not represent a subject image of a frame of a prescribed ordinal number; an accumulating device for accumulating an amount of data from the reference frame, wherein the amount of data is the amount of subject-image data that has undergone complete compression processing and differential compression processing; a determining device for determining whether an accumulated value obtained from said accumulating device has exceeded a value calculated from an amount of data receivable by a terminal device to which a moving picture file is to be transmitted; and a control device, responsive to a determination by said determination device, for controlling said compressing device in such a manner that complete compression processing is applied to subject-image data representing a subject image of a frame that has exceeded the receivable amount of data owing to execution of compression processing; wherein said determining device determines whether the accumulated value obtained from said accumulating device has exceeded a first amount of data receivable by a first terminal device to which a moving picture file is to be transmitted, or a second amount of data receivable by a second terminal device to which a moving picture file is to be transmitted; and said control device has: a first control device for controlling said compressing device in such a manner that complete compression processing is applied to subject-image data representing a subject image of a frame that has exceeded the first receivable amount of data owing to execution of compression processing; and a second control device for controlling said compressing device in such a manner that complete compression processing is applied to subject-image data representing a subject image of a frame that has exceeded the second receivable amount of data owing to execution of compression processing; wherein the reference frame begins a first partition, the frame that has exceeded the first receivable amount of data begins a second partition, a last frame before the frame that has exceeded the first receivable amount of data ends the first partition, and the first partition comprises more than one frame to which complete compression processing has been applied.
