An image processing device is comprised of a parameter storing unit (i) storing a plurality of inverse gamma correction parameters, color conversion parameters, gamma correction parameters and the like, and (ii) selecting one parameter from each of a plurality of such parameters according to an inputted image signal. Further, the image processing device includes an image signal processing unit performing image signal processes such as inverse gamma correction, color conversion, gamma correction and the like, on the basis of the parameters selected by the parameter storing unit.

Image processing device

An image processing support system has an image processing support device that includes a parameter calculating unit for calculating parameters on the basis of results of measurements made by a measuring device and target values notified by a target setting unit. The image processing support system also has an image processing device that includes an image signal processing unit for performing image signal processing such as inverse gamma correction, color conversion, and gamma correction on the basis of the parameters which are an inverse gamma correction parameter, a color conversion parameter, and an gamma correction parameter stored in a parameter storing unit. Further, the image processing support system has a display device for displaying an image signal.

Image processing support system, image processing device and image display device

A data transfer system comprises a plurality of terminals; a plurality of high-speed data transfer units connected to the terminals through a network, each data transfer unit comprising a plurality of storage devices and a storage device group control device or unit for controlling readout of data from the storage devices, and dividing and storing data requested by the terminals; a virtual storage device group controlling device or unit for controlling readout of data from virtual storage device groups, each virtual storage device group being constructed by selecting a storage device from each high-speed data transfer unit; and an instruction conversion unit or device for receiving a data readout instruction on the basis of data requests output from the terminals, which instruction is given to the virtual storage device groups, from the virtual storage device group control unit or device, and converting the instruction into a data readout instruction to the storage devices from the storage device group control unit or device. In this data transfer system, the load for the data transfer processing is equally distributed among the high-speed data transfer units even when data transfer requests are output from plural terminals.
