摘要： Correction for color fog is securely achieved with limited load of processing. The RGB image data are converted into the luminance and the chromaticity values C1, C2, then a highlight point and a shadow point are determined and are connected to define the axis of the color solid. The color solid is rotated so as that the axis becomes parallel to the luminance axis Y and is so translated in parallel manner that the pixel of the minimum luminance coincides with the original point of the color space.

摘要： Software of a simple configuration checks whether an original image to be corrected is an image picture, and an image correction process based upon a formed histogram of the original image is not performed for an image different from the image picture. An image processing condition is set in accordance with the formed histogram to perform the image correction process for the original image. An image processing method judges from a shape of the formed histogram whether the original image is an image picture, and does not perform not perform the image correction process for the original image if it is judged that the original image is not an image picture.

摘要： According to an image processing method for performing color processing in accordance with a plurality of image objects, image data representing the plurality of image objects is input. The relationship between the plurality of image objects is analyzed. The plurality of image objects are grouped based on the result of analysis. The same color processing condition is set for the plurality of image objects belonging to the same group. Thus, the same color processing condition is set for the plurality of image objects divided from a single original image, thereby obtaining a high-quality output image.

摘要： An image processing apparatus is capable of appropriately extracting a frame of an output target from a moving image. The image processing apparatus includes an analysis unit configured to analyze a plurality of analysis regions in each of a plurality of frames included in the moving image, an extraction unit configured to extract the frame of the output target from among the plurality of frames by comparing analysis results of the plurality of analysis regions in each of the plurality of frames analyzed by the analysis unit for each analysis regions corresponding to each other between the plurality of frames, and an output unit configured to output the frame of the output target extracted by the extraction unit.
