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.

摘要： In a device for combining a plurality of images having a same photograph range, a position shift between the images having the same photograph range is detected, and the position shift of the images is corrected, and after the position shift is corrected, similarity of the respective portions between the images is evaluated, and the image combining method is changed according to the similarity evaluation. Therefore it is possible to create an image having no position shift due to the shaking of a camera and object blurring due to the movement of the object. Moreover, whether the images are combined or not is determined according to the similarity, hence the processing load is reduced and an image having no object blurring can be created.

摘要： A display device separates a size-reduced image into a plurality of sub-areas in such a manner that a sub-area farther away from the light sources becomes wider than a sub-area closer to the light sources; compares, in each of the sub-areas, the luminance values of each pixel in a direction perpendicular to the array direction; and selects a pixel having the greatest luminance value, thereby creating line information. The display device then compares a light distribution that is a synthesis of light radiation patterns of the light sources with a luminance distribution indicated by each line information and then adjusts the emission intensity of each of the light sources.
