Abstract: Provided are a transmission device, a transmission method, and a program capable of performing rate control suitable for an image quality priority image. A basic parameter value decision section (28a) decides, for a frame image that is not an image quality priority image, values of parameters used for encoding an encoding unit that is a part or whole of the frame image, by applying the difference between a control amount and a target value to a predetermined control rule. An image quality priority parameter value decision section (28b) decides, for the frame image that is the image quality priority image, values by which the data size of the generated image data becomes larger than those decided by applying the difference between the control amount and the target value to the predetermined control rule as the values of the parameters used for the encoding unit of the frame image.

Abstract: An image data acquirement section of an image processing apparatus acquires data regarding a frame of a moving image generated by a server. A decoding/decompression section repeats a cycle of a decoding/decompression process for each of frames at a rate higher than the frame rate of the moving image. An image processing section repeats a cycle of applying a necessary image process to each of the frames at the rate higher than the frame rate of the moving image. The display control section outputs the data regarding the frame ready for displaying to a display panel at the rate higher than the frame rate of the moving image.

Abstract: In a server, a client information acquiring section acquires information related to a user operation from an image processing device. An operation status identifying section of an image generating section identifies the contents displayed on the image processing device side at the time when the user operation is performed. A drawing section generates a frame corresponding to the details of the user operation and the contents displayed at the time when the user operation is performed. A discard processing section determines whether or not to discard the data, on the basis of the contents of a provisional frame generated before the detection of the user operation.

Abstract: A transmission apparatus, a transmission method, and a program that can reduce the number of times that useless transmission of image data is performed due to a failure in reception of image data indicating a reference destination. A transmission failure likelihood data management section checks the likelihood of a failure in transmission of first image data. Second image is an image rendered in a frame buffer for the first time after a timing when a predetermined time has elapsed since the transmission of the first image data. An encoding processing section controls whether or not to generate second image data requiring no reference destination, depending on the likelihood of the failure in the transmission of the first image data at a timing of encoding the second image.

Abstract: In an image processing apparatus, an image acquisition section acquires captured images from a stereo camera of a head-mounted display. An image correction section performs correction on a partial image-wise basis, a partial image being smaller than one frame, while referring to a displacement vector map representing displacement vectors of pixels required for the correction. A feature point extraction section extracts feature points from partial images, and supplies the feature points sequentially to a feature point comparison section. The feature point comparison section associates feature points in a plurality of images with one another. A space information acquisition section acquires information as to a real space on the basis of correspondence information as to the feature points.

Abstract: A dividing section of a server divides, along a common boundary, a plurality of images that are formed by an image forming section and correspond to respective frames of a moving image, to form image blocks. A first coding section compression-codes one of the plurality of images in units of the image block. A second coding section compression-codes another one of the plurality of images in units of the image block, using data compression-coded by the first coding section. A communication section transmits data of the compression-coded image blocks to an image processing apparatus.
