Abstract: 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.

Abstract: To change the amounts of correction used to correct a specific color in video signals depending on a shooting situation or an image to be captured, an imaging apparatus includes: selection means for selecting desired shooting mode information from pieces of set shooting mode information, each of the pieces of shooting mode information including information concerning a specific color determined depending on a predetermined shooting condition; extraction means for extracting video signals of a specific color from video signals on the basis of the selected shooting mode information; color difference detection means for detecting color difference data of the specific color from the extracted specific-color video signals; and correction reference data storage means for storing pieces of correction reference data, serving as references for correcting the specific color to a predetermined color.

Abstract: 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.

Abstract: When color correction is performed on a particular color of a video signal, in order to change a color correction amount according to image-taking circumstances or capture video images without influencing colors not to be corrected, image-taking mode information containing information on particular colors determined according to predetermined image-taking conditions is set. There are provided selection means for selecting desired image-taking mode information from the image-taking mode information, and storage means for storing color convergence parameter values containing position data indicative of a position of a predetermined color in a color-difference plane, correction range setting data for setting to a correction range a predetermined range centered at the position of the predetermined color, and convergence coefficient data for converging a particular color corresponding to the correction range to the position indicative of the predetermined color.

Abstract: An imaging apparatus which is supplied with an imaging signal taken by an imaging device, and outputs a video signal obtained by applying a predetermined image processing to said imaging signal is disclosed, wherein; when the most-dark point of the imaging signal is shifted from an achromatic axis, a black balance control is carried out so that the most-dark point is corrected in the achromatic axis direction based on the black adaptation rate in consideration of an adaptation effect of human eye to black.

Abstract: In the present invention, RGB data outputted by a transmission side CRT monitor 3 is converted by a profile P1 stored in a converter 11 into XYZ data which is corrected in agreement with the viewing conditions on the transmitting side by having reference to detection signals from sensors S1, S2 so that the data is outputted as L+M+S+ data. A viewing condition conversion circuit 15 refers to detection signals from sensors S3, S4 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 16. The converter 16 refers to a profile P4 to convert the XYZ data into RGB data which is outputted to a CRT monitor 4. 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.
