摘要： When a motion image is to be compressed, the present invention divides a high-resolution still image into image segments to perform a motion image encoding process on each image segment. In this instance, the importance of each image segment and the relativity of each image segment with another image segment are computed. The image segments are then aligned in the order of importance to determine a picture type for motion image encoding in accordance with the computed relativity. Encoding is performed in accordance with a determined encoding sequence and picture type. Further, the rate control bit allocation amount for motion image encoding is increased for highly important image segments. Therefore, the present invention makes it possible to exhibit a high overall image compression efficiency while avoiding image quality deterioration in an important portion of a still image by using a motion image compression technology for still image compression.

摘要： The present invention provides an image coding apparatus and an image coding method for reducing arithmetic processing while keeping a high compression ratio. A coding process necessary for the bi-prediction motion search can be effectively reduced by determining a block size for a bi-prediction motion search or a center position for a motion search on the basis of a result of a motion search of a unidirectional prediction. Further, a compression ratio can be also kept as high as possible, because the block size or the center position are obtained on the basis of the result of the motion search of the unidirectional prediction.

摘要： A moving picture recording system includes a communicable moving picture recording apparatus and a mobile terminal. In this case, the communicable moving picture recording apparatus has a recording module which records a moving picture in a recording medium and a transmitting module which transmits information indicating an in-recording state, while the recording module is recording the moving picture in the recording medium. The mobile terminal has a receiving module which receives the information indicating the in-recording state and an informing module which informs a user that the communicable moving picture recording apparatus is recording a moving pictures when the information indicating the in-recording state is received.
