摘要： In order to transfer an image encoded at a high compression rate and suitably increase the resolution of the transferred image, it is provided an image transfer system, comprising: an image transmission unit that transmits an image; and an image reception unit that receives the image transmitted from the image transmission unit. The image transmission unit scales down the image, and transmits the scaled-down image to the image reception unit. The image reception unit calculates an angle between a line displayed in the image transmitted from the image transmission unit and a horizontal direction of the image in correspondence with pixels included in the image, scales up the image transmitted from the image transmission unit, and removes an aliasing component of the scaled-up image based on the calculated angle.

摘要： The present invention relates to a technology of appropriately improving image resolution. According to an image signal processing method of the present invention, an input video signal contains an image signal whose pixel size is converted at a specified magnification scale. The input image signal is used to calculate sampling frequencies for image signals before and after the pixel size conversion. A ratio of sampling frequencies before and after the pixel size conversion is used to determine the specified magnification scale. A sampling phase for the image signal before the pixel size conversion is calculated from the input image signal after the pixel size conversion. A sampling carrier for the image signal before the pixel size conversion is generated from the sampling frequency and the sampling phase both before the pixel size conversion.

摘要： The objective is to reduce the amount of code in the encoding/decoding process for a moving picture. In an intra prediction process, the degree of ease of estimating the prediction direction or the block mode for a block to be decoded is determined based on the prediction direction data or the block mode for multiple adjacent blocks which have been decoded previously and which are adjacent to the block to be decoded; the prediction direction data or the block mode for the block to be decoded is decoded based on the result of said determination; and intra prediction is performed based on the decoded prediction direction data or the block mode to generate decoded image data.
