摘要： An image correction apparatus calculates a feature value indicative of an average brightness of an input image from the pixel values of the input image and determines a pixel value at a boundary for correcting each pixel of the input image to make it brighter or darker by using the calculated feature value of the input image. The image correction apparatus calculates, with respect to the pixel value of each pixel of the input image, an area for determining a contrast correction amount for a pixel value smaller than the pixel value at the determined boundary such that a pixel is to be made darker and calculates an area for determining a contrast correction amount for a pixel value larger than the pixel value at the determined boundary such that a pixel is to be made brighter, thereby correcting the contrast of the input image by using the calculated areas.

摘要： An image correction apparatus stores therein a plurality of correction curves for determining a correction amount, calculates a feature value of average brightness in an input image, determines whether the calculated feature value is equal to or greater than a first threshold, and, for the input bright image with the feature value equal to or greater than the first threshold, counts the number of pixels equal to or less than a second threshold in the input image.

摘要： An image generating apparatus that generates an output image using a difference between an uncorrected pixel in an image and a smoothed pixel obtained by smoothing the uncorrected pixel. The image generating apparatus includes a storage unit, a tone-converted uncorrected pixel generating unit, a tone-converted smoothed pixel generating unit, and an output image generating unit. The storage unit stores an uncorrected pixel tone table for converting the uncorrected pixel and a smoothed pixel tone table for converting the smoothed pixel. The tone-converted uncorrected pixel generating unit converts the uncorrected pixel to a tone-converted uncorrected pixel based on the uncorrected pixel tone table. The tone-converted smoothed pixel generating unit converts the smoothed pixel to a tone-converted smoothed pixel based on the smoothed pixel tone table. The output image generating unit generates the output image based on a difference between the tone-converted uncorrected pixel and the tone-converted smoothed pixel.

摘要： When different images are combined, the corresponding parts are to be aligned accurately. To thus combine images, the feature point of each pixel is calculated from each original image using an operator (filter). The pixels are divided into blocks that the resolution matches that of the reduced image of each original image, and an expectation value map for registering the expectation value of the feature point of each block is drawn. Feature points are expected from the expectation values which the expectation value map holds, and reduced images are superposed one on the other. The feature points of the original images corresponding to the feature points between which the correspondence is derived from the reduced images are extracted, and the original images are superposed one on the other using the extracted feature points.
