摘要： A video reproduction application program monitors whether or not blend processing for superimposing one of two images on the other is executed, and executes all decode processings (normal decode processings), when the blend processing is not executed. On the other hand, when the blend processing is executed, a specific processing is executed in which decoding of a color component is omitted from decode processing for decoding the images to be subjected to the blend processing. As a result, the load on the system is reduced.
