摘要： A communication terminal performs a discrete cosine transform and a quantization process in accordance with a selected coding mode so as to reduce loads caused by these processings and suppress degradation of picture quality. When performing coding of a moving picture inputted through a picture input part, a control part determines which coding mode among 4×4 intra prediction coding on a luminance signal, 16×16 intra prediction coding, intra prediction coding on a color-differential signal, and inter prediction coding is performed. In accordance with the selected coding mode, and in view of a predictive error, the processing content in the discrete cosine transform and the quantization process is switched.

摘要： In a moving picture encoding apparatus, a processing load detection section detects a load and outputs load information and a video encoder judges a load level based on the load information. A start pixel in target pixels is determined depending on the load level, the evaluation value is calculated from pixels specified by the start pixel, a encoding cost is calculated based on the evaluation value to select one of prediction modes for minimizing the encoding cost. The start pixel is so selected as to exclude the pixels which are spatially neighboring to reference pixels for prediction, instead of all pixels within a 4×4 pixel block as the processing load becomes large. Thus, the picture processing amount is reducing while suppressing the deterioration of the encoding performance.

摘要： While accuracy of motion compensated prediction is kept high, reduction in processing amount is made possible. When motion compensated prediction is performed on inputted image data by a motion vector detection section, first, reference is made to past three reference frames stored in a reference image storage section, integer search is performed on the image data for each macroblock, and a motion prediction vector is detected by this. Based on the detection result of the motion prediction vector, a reference frame most appropriate for execution of motion compensated prediction is determined for each blocks. Next, based on the determination result, it is judged whether or not reference frames regarded as most appropriate for all blocks (nine blocks) are coincident to each other. As a result of the judgment, when the same reference frame is selected for all candidate blocks, only the reference frame regarded as most appropriate is made the object of sub-pel search, and the motion prediction vector is detected with sub-pel pixel accuracy.
