20090153683 | IMAGE ACQUISITION APPARATUS, IMAGE PROCESSING APPARATUS, IMAGE ACQUISITION SYSTEM, AND IMAGE PROCESSING PROGRAM - In an image acquisition apparatus, RAW data obtained in image acquisition with an imager in which a color filter is disposed in a front face is divided into each identical color by a RAW data dividing unit, a compression coding processing unit produces coded data of each color by compressing the RAW data at a compression rate controlled for each color, and the coded data of each color is recorded in a recording unit. A motion compensation unit compensates a relative positional relationship between frames by estimating a motion of a subject between frames of plural images, using specific color division coded data which is decoded by the compression coding processing unit and a RAW format data reproducing unit, the specific color division coded data being coded data of a color close to a peak of spectral sensitivity of human vision in the coded data of each color. | 06-18-2009 |
20090172754 | IMAGE DISTRIBUTION SYSTEM, SERVER AND CLIENT TERMINAL - In an image distribution system which distributes an electronically recorded image to a client terminal through a server, when a high-resolution image of a desired image requested from the client terminal is produced using a single image or plural images recorded in an image recording unit in a high-resolution processing unit on the side of the server, a desired parameter in parameters which can be specified by the client terminal is transmitted from the client terminal to the server, the parameters including a part of or all items of quality parameter for setting the image quality of the produced image for the desired image. On the side of the server, the high-resolution image whose image quality is controlled by the quality parameter is produced and distributed to the client terminal. | 07-02-2009 |
