    摘要： Flicker occurs in a flicker-noticeable area consisting of pixels with no pixel value variations. An image processing device (100) includes a variance calculation unit (101) that obtains a variance of an area consisting of a target pixel and neighboring pixels included in a first frame, and changes, according to the variance, the rate at which an error generated at the target pixel through tone level restriction is distributed within the frame and between frames. The image processing device (100) includes an error diffusion unit (113) that distributes the error generated at the target pixel to the neighboring pixels included in the first frame based on an intra-frame error diffusion rate and an intra-frame error distribution weight, and distributes the error generated at the target pixel to a target pixel and neighboring pixels included in the second frame based on an inter-frame error diffusion rate and an inter-frame error distribution weight.

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： 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).
