    摘要: An image correction method can perform adaptive correction processing to a taken image by a simple construction in a short time, and includes the steps of: computing window region local difference values for a plurality of neighboring pixels, each of the window region local difference values being a difference value between image data of a notice pixel (33a) in a difference value determination region (32) formed of a whole or a part of a screen area of an input image (31) and image data of a neighboring pixel in a window region (33) set around the notice pixel (33a), thereby determining a maximum local difference value which is a maximum value of the window region local difference values in each window region; determining a threshold value reflecting a characteristic of the input image on the basis of the maximum local difference value; producing adaptive filter coefficients for respective pixels of the input image by using the threshold value; and performing filter processing of the input image by using the adaptive filter coefficients.

    摘要: Provision is made for obtaining a high-quality image with noise, such as ringing, reduced. An image processing device includes an image correction means for applying image-shake correction processing to an input image; a correction-image characteristic detection means for detecting a characteristic of a correction image obtained through the image-shake correction processing; a first characteristic-determination means for outputting selection information, based on a characteristic-detected correction image obtained through detection of the characteristic of the correction image; and an image outputting means for outputting the input image or the correction image, based on the selection information. As a result, it is made possible to obtain a high-quality image with noise reduced.
