摘要： An image processing system includes a reception unit, a derivative calculation unit, a reference image creation unit, and an interpolated image creation unit. The reception unit receives an original image signal formed by a plurality of pixel signals in which any of first through mth (m being an integer three or greater) color signal components is lacking. The derivative calculation unit calculates a derivative for the pixel signals using two pixels sandwiching a pixel corresponding to the pixel signals. The reference image creation unit creates a primary reference image using the first color signal component, which has the largest number of elements among the pixel signals of the original image signal. The interpolated image creation unit creates an interpolated image by interpolating all of the color signal components using the primary reference image. At least one of the primary reference image and the interpolated image is created using the derivative. As a result, the occurrence of false colors is suppressed while using a multiband color filter.

摘要： An image processing system includes: a weight determination circuitry configured to determine a band containing important information from among a group of images, which are acquired by a plurality of sensors, and to express a degree of importance of the band as a weight; a calculation circuitry configured to calculate, using the weight, an amount calculated based on a gradient of an image based on a gradient of each image, that is calculated based on the group of images, in order to restrict a gradient of an output image; and an image optimization circuitry configured to compose the output image using the amount calculated based on the gradient of the image.

摘要： The image data display system according to the present invention makes it possible to comprehend a global distribution of measurement values and a change in details of the measurement values simultaneously. In the present invention, a color information conversion unit converts the measurement values to color information for representing the global distribution of the measurement values. A detail extraction unit extracts detail information of the measurement values from the measurement values. A detail adjustment unit adjusts the strength of detail information and generates adjusted detail information. A color information adding unit adds color information on the basis of the adjusted detail information.

摘要： Provided is an information processing system configured to: receive a plurality of images; select a standard image; search, in extracting partial images for complementing a too bright region/too dark region in the standard image from a reference images, using correction images obtained by subjecting each of the images to multivalued processing for each division of luminance components, for regions having matching shapes of respective regions included in the correction image of the standard image and the correction images of the other images; and complement image portions corresponding to the too bright region and/or too dark region in the correction image of the standard image using image portions, which are matching regions and correspond to appropriately bright regions, to thereby generate a synthetic image. Each image is dividable into at least three values: a too bright region, an appropriately bright region, and a too dark region, and has a relationship in which a boundary luminance between the too bright region and the appropriately bright region aligns with a boundary luminance between the appropriately bright region and the too dark region in a darker image having an adjacency relationship therewith.
