An object of the present invention is to improve the image quality of images obtained during travelling even in inferior environmental conditions. A camera-is mounted in a train-, and a camera-is mounted in a train-. Each of the camera-and the camera-images the same physical object at different times while moving along the same track. A processing apparatusgenerates a synthetic imageby synthesizing images related to the same physical object imaged by the cameras-and-while moving along the same track, and displays the same on a display screenA.

Image synthesizing system and image synthesizing method

The system includes a display device causing a display unit to display video; a data transmission unit that transmits, to the display device, video data generated in a predetermined format based on information decoded from encoded information, and interpolation data for interpolating differences between the predetermined format and a format when decoding from the encoded information; an interpolation data selection unit that selects a kind of interpolation data to be transmitted to the display device, on the basis of priorities for a plurality of kinds of the interpolation data capable of being generated based on the encoded information; and a display processing unit that acquires the video data and the selected kind of the interpolation data in the display device, and causes the display unit to display video resulting from interpolation of the video data based on the interpolation data.

Image playback device, display device, and transmission device

The image transmission system, which transmits image data from a transmission side and performs image processing at a reception side, is provided with: an image transmission device that encodes an input image and outputs and a bitstream; an image reception device that receives and decodes the bitstream and performs image processing; a bit precision information generation unit that generates bit precision information for each region in the image; a quantization control unit that controls the quantization step width in a quantization process performed in the image transmission device in accordance with the bit precision information generated by the bit precision information generation unit; and an image processing unit that performs image processing using the decoded image that has been decoded by the image reception device. The bit precision information generation unit switches the method for generating bit precision information in accordance with the processing mode of the image processing unit.

Image transmission system

An image compression/decompression device achieving increased utilization efficiency of the memory bandwidth in the access to the memory used for the compression/decompression operation while maintaining ill effect on the images at a low level is realized. The image compression/decompression device comprises a data conversion unit which reduces the data access rate when original images (as input images at the time of performing the compression) and reference images (used for performing the interframe prediction) are stored in the memory by accessing the memory. The access to the memory is performed in an address sequence (order) that differs between data write and data read. This makes it possible to increase the utilization efficiency of the memory bandwidth, and further to reduce the capacity of the buffer memory used for the data read.

Video image compression/decompression device

An image encoding apparatus is provided which realizes an encoding process at a high bit rate without degradation in image quality at boundary parts within a picture. The image encoding apparatusincludes: a plurality of entropy encoding sectionsandfor generating bit streams by entropy-encoding intermediate data generated from syntax elements of image data; and an encoding control sectionfor supplying the intermediate data to any of the entropy encoding sections. The encoding control sectiondetermines the entropy encoding section that performs an entropy encoding process by a frame in accordance with the processing status of each of the entropy encoding sections.
