    摘要： An image processing device that, even when a degradation model differs from a real degradation process of an obtained low-resolution image, generates a high-resolution image while restricting noises from occurring due to differences between the degradation model and the real degradation process. The image processing device includes: an enlargement interpolation unit generating a first high-resolution image that is higher in resolution than the low-resolution image; a super resolution processing unit generating, from the low-resolution image, a second high-resolution image; a feature generating unit generating features by using the low-resolution image; a difference calculating unit calculating difference values between values of pixels; an adjustment unit calculating corrected difference values by correcting the difference values by using the features; and a combination unit generating a third high-resolution image by adding corrected difference values to values of corresponding pixels in the first high-resolution image.

    摘要： An imaging device for supporting the user to generate satisfactory synthesized images, not missing photo opportunities. The imaging device generates a plurality of still images continuously and generates a synthesized image from the still images. While the shooting button is pressed to instruct continuous shooting, the imaging device performs a process in which it writes still image data, which is obtained by the continuous shooting, into a recording medium sequentially. After the continuous shooting ends, the imaging device enters a wait state to wait for a new instruction, and then upon receiving an instruction to start generating a synthesized image, it performs a process of generating a synthesized image by using a plurality of pieces of still image data stored in the recording medium.

    摘要： Color sub-pixel display is performed with a display device that has three light emitting elements for emitting three primary colors R, G, and B, respectively, aligned in an x-y matrix. Color information at pixel accuracy is separated into luminance data at pixel accuracy and chroma data at pixel accuracy. From the luminance data at pixel accuracy, luminance data at sub-pixel accuracy is generated. The luminance data at sub-pixel accuracy and chroma data at pixel accuracy are synthesized, whereby color information at sub-pixel accuracy is obtained.

    摘要： A display method includes obtaining three-times magnified image data, which is made up of sub-pixels and with which a raster image to be displayed currently is magnified by three in the first direction. A filtering process on the three-times magnified image data is based on factors that are weighed in accordance to the degrees of contribution to luminance of the three primary colors of R, G, and B. The weighted data are allocated to sub-pixels of the three-times magnified image data that have been subject to the filtering process. The sub-pixels are formed by the three light-emitting elements that form a pixel to thereby enable the display device to perform display.

    摘要： In a display device, three light-emitting elements, which respectively emit light of the three primary colors of R, G, and B, are aligned in a fixed order in a first direction to form one pixel. A plurality of such pixels are aligned in a the direction to form one line. A plurality of such lines are aligned in a second direction, which is orthogonal to the first direction, to form a display screen. With this display device, a three-times magnified pattern, with which a target pixel in a raster image to be displayed currently is magnified by three in the first direction, is determined dynamically in accordance with a rectangular reference pattern of 3×3 pixels consisting of the target pixel and pixels surrounding the target pixel. Display is performed upon allocating this three-times magnified pattern to the three light-emitting elements that comprise one pixel. Character interval adjustment and color display of sub-pixel precision precision are enabled.
