摘要： The present invention relates to an image processing device that can reproduce a state in which, using a first display device, an image is displayed on a second display device having a characteristic different from that of the first display device, an image processing method, and a program. A motion detecting unit 100 detects motion of an image from an input image signal. A sub-field developing unit 200 develops the input image signal over sub-fields. A light-intensity integrating unit 300 calculates, in a simulated manner, the light intensity integrated on the retinas of a person at the time the person sees the input image signal, from the direction of the motion of the image and a light emitting pattern of the sub-fields, and displays the image with the calculated light intensity on the first display device. The present invention is applicable to the case where, for example, using an LCD, a state in which an image is displayed on a PDP having a characteristic different from that of the LCD is reproduced.

摘要： In encoding input image data including first and second images, the first image is divided into blocks. A second block corresponding to a first block that is one of the blocks is detected from the second image. Pixels forming the first and second blocks are sorted in order according to pixel values. Block difference data indicating the amount of change in the pixel values of the sorted pixels between the first and second blocks is determined and encoded. In decoding, block information identifying the second block, sort-order information indicating the sorted pixels forming the first block, and the encoded block difference data are obtained. The encoded block difference data is decoded. The decoded block difference data and the second block identified by the block information are used to generate pixel values of the first block. The generated pixel values are reverse-sorted according to the sort-order information.

In a spectrum combining unit 16, the extracted high-frequency-component DCT spectrum data is combined with low-frequency-component DCT spectrum data output from the DCT transform unit 12. Subsequently, a broad-range audio signal having combined high frequency components and low frequency components is output. The present invention can be applied to cellular phones.
