ABSTRACT:
An image processing apparatus includes a decoding unit for performing a decoding process on coded data of a moving picture on a frame-by-frame basis, and a controller for controlling the decoding unit. The controller designates a first decoding condition using multiple attributes, such as resolution level, precinct, component, or layer, for each frame, and causes the decoding unit to perform the decoding process on those code streams that satisfy the first decoding condition among the coded data. If a decoding time required to perform the decoding process under the first condition is equal to or longer than a prescribed time period, the controller allows the decoding unit to finish the decoding process for a current frame. If the coding time is shorter than the prescribed time period, the controller designates a second condition as to the attributes for the current frame to cause the decoding unit to perform the decoding process on those codes streams that satisfy the second condition.
