    摘要： When read image data is mapped outside the range of a page memory, the invention allows a coordinate value to be stored in the page memory to be mapped after being shifted into the page memory, thereby allowing efficient utilization of the page memory, and in order to achieve the above-described object, the invention employs the configuration that when an integral number coordinate value (X.sub.int, Y.sub.int) is out of the range of an image memory, an X-coordinate conversion circuit and a Y-coordinate conversion circuit shift the coordinate value so that it comes in the range and outputs a coordinate value (XINT, YINT) and this shifting process allows read image data outside the image memory to be shifted into the area of the image memory to be stored therein and when image data stored in the image memory is read out, the coordinate is read out in reverse on the assumption that a shifted origin coordinate O (X.sub.smin, Y.sub.smin) serves as the coordinate origin of the image memory and the origin coordinate O (X.sub.smin, Y.sub.smin) is automatically stored in a register when the reading of the image is completed.

    摘要： An aim of the invention is to achieve an image processing method that performs color information correction of an image more naturally with a simple configuration. The image processing method of the invention is an image processing method that performs color information correction of image data that have been input, and includes an information calculation step (S11), a characteristic calculation step (S12), a color information correction step (S13), and an output step (S14). The information calculation step (S11) calculates the color information of the image data. The characteristic calculation step (S12) calculates the visual characteristic information in accordance with the color information. The color information correction step (S13) corrects the color information based on the visual characteristic information that is calculated in the characteristic calculation step (S12). The output step (S14) outputs the image data after color information correction based on the color information that has been corrected in the color information correction step (S13).

    摘要： The first color gamut conversion unit 102 limits, in a visually natural manner, an output signal to a signal within a range of the DCI color gamut through well-known color gamut conversion processing when there is a color region exceeding the DCI color gamut, the output signal being obtained through the imaging by the imaging unit 101 and represented by the primaries (R, G, and B) determined by a color filter of an image sensor of the camera. It is to be noted that a color gamut conversion technique may be any technique which can limit a color gamut such as gamut conversion processing (Non Patent Literature: “Fundamentals of Color Reproduction Engineering”, Corona Publishing Co., Ltd., pp. 178-180).

    摘要： An image processing apparatus for automatically improving the contrast of an input image that is obtained from a digital camera or the like, and obtaining a sharper and clearing image. A contrast improvement unit (11) performs a contrast improvement process on the input image by comparing an object pixel in the input image with pixels in the surrounding area. An image combination unit (12) combines the enhanced image obtained by the contrast improvement process with the input image. The combined image is then output to a desired device such as a printer by an image output unit (13).
