An information processing system is disclosed. The system includes a first information processing device; and a second information processing device, the first information processing device transmitting data to the second information processing device in response to a request from the second information processing device. The first information processing device includes first storage means and transmission means. The second information processing device includes reception means, second storage means, display control means, revision parameter setting means, and image processing means.

Image processing device and method for correcting an image according to a revised correction value

An image pickup apparatus includes: a dimming device configured to adjust light quantity of incident image pickup light; an image pickup device configured to obtain an image pickup signal based on image pickup light emitted from the dimming device; and a color correction processing section configured to perform color correction on the image pickup signal that is obtained by the image pickup device, based on information relating to light quantity of the image pickup light emitted from the dimming device. The color correction processing section performs the color correction to allow a color balance value of the image pickup signal to be substantially constant independent of the light quantity of the image pickup light emitted from the dimming device.

Image pickup apparatus, color correction method, and color correction program

In an image pickup apparatus, a particular color signal is extracted from an input video signal based on the selected image taking mode information, white balance control amount calculating means calculates a control amount based on the extracted video signal of the particular color, the white balance correcting means corrects the white balance of the video signal according to this control amount, and then the color correcting means corrects the particular color signal in the video signal based on color correction parameter values set in advance. Subsequently, low chroma color suppression processing means corrects the gain amount of the video signal corresponding to the predetermined area centered at the origin in the color difference plane, from among the video signal corrected by the color correcting means, thereby correcting the particular color in the video signal and also correcting white balance deviated due to the correction of the particular color.

Image pickup apparatus

An image-processing apparatus for processing the image data input from an image-handling device and then outputting the image data to another image-handling device. The apparatus comprises a black-adaptation correction device. The black-adaptation correction device corrects the image data in consideration of the fact that adaptation to black varies from person to person, if the darkest points of the image-handling devices differ from each other. Since the image is so corrected, the colors of the images produced by the image-handling devices look almost the same in spite of the fact that the darkest points of the image-handling devices differ from each other.

Image-processing apparatus and image-processing method

In the present invention, RGB data outputted by a transmission side CRT monitor is converted by a profile P stored in a converter into XYZ data which is corrected in agreement with the viewing conditions on the transmitting side by having reference to detection signals from sensors S , S so that the data is outputted as L M S data. A viewing condition conversion circuit refers to detection signals from sensors S , S to correct the L M S data in agreement with the viewing conditions on the reception side to supply the resulting XYZ data to the converter . The converter refers to a profile P to convert the XYZ data into RGB data which is outputted to a CRT monitor . This equates color appearance of a picture on an input device on the transmission side to that of a picture on an output device on the reception side.
