摘要： For each pixel read from an imaging device, a horizontal counter value and a vertical counter value corresponding to the pixel are supplied from a signal generator to a distance computation section via an optical-axis-center coordinate setting section and an up-and-down and right-and-left weighting section. In the distance computation section, the distance to the optical-axis center is computed, and correction coefficients for the zoom wide end and for the zoom tele end, which correspond to the distance, are obtained by look-up tables.

摘要： When color correction is performed on a particular color of a video signal, in order to change a color correction amount according to image-taking circumstances or capture video images without influencing colors not to be corrected, image-taking mode information containing information on particular colors determined according to predetermined image-taking conditions is set. There are provided selection means for selecting desired image-taking mode information from the image-taking mode information, and storage means for storing color convergence parameter values containing position data indicative of a position of a predetermined color in a color-difference plane, correction range setting data for setting to a correction range a predetermined range centered at the position of the predetermined color, and convergence coefficient data for converging a particular color corresponding to the correction range to the position indicative of the predetermined color. Color convergence parameter values for the corresponding particular color from the storage means is selected and set on the basis of the selected image-taking mode information, and a particular color in a video signal is corrected into the predetermined color on the basis of a correction amount calculated on the basis of the set color convergence parameter values.

摘要： An image processing apparatus and method and a recording medium therefor control the occurrence of a change in a hue. The histogram of a luminance signal Y is generated in a first step S1. In a second step S2, the histograms of the luminance signals Y are accumulated to generate a cumulative histogram, and the cumulative histogram is subjected to logarithmic approximation thereby to generate a lookup table (LUT) for correcting luminance signals. In a third step S3, a color-difference signal correction parameter LUT is generated by referring to the LUT for correcting luminance signals. In a fourth step S4, an input luminance signal Y is applied to the LUT for correcting luminance signals thereby to acquire a corrected luminance signal Y0. In a fifth step S5, the input luminance signal Y is applied to a color-difference signal correction parameter LUT so as to acquire a correction parameter k. In a sixth step S6, input color-difference signals Cr and Cb are multiplied by the correction parameter k to acquire corrected color-difference signals Cr0 and Cb0.

摘要： An image-processing apparatus for processing images, whereby the image-processing apparatus includes an image capture unit, a filter, and an extraction unit. The image capture unit acquires image signals composed of multiple color components of a 2×2 color-coding array. The filter then calculates an average pixel value associated with any (2n−1) pixels acquired by the image capture unit, whereby each of the filtered (2n−1) pixels include a target pixel and adjacent pixels having the same color component as that of the target pixel, and the calculated average is designated as the average of the target pixel and the adjacent pixels. At the extraction unit the pixel having the average calculated by the filter as the pixel value is extracted at an extraction rate of 1/(2n−1), where n is a positive integer value.

摘要： A distance calculation method and an imaging device that can be applied to a digital camera. The method includes calculating a distance between a point corresponding to an optical axis of a lens sub-system of the imaging device and an input point, and using the calculated distance to correct defects such as shading that occur in formed images due to peripheral light fall-off in the lens sub-system. The distance is approximated by a polygon having five or more sides, preferably having 8 or 16 sides. The distance is calculated by a disclosed function having constant coefficients, so that distances can be calculated by simple hardware.

摘要： The present invention relates to apparatuses and methods for image processing, recording media, and programs in which extraction processing utilizing all pixels can be conducted. When a horizontal-component low-pass filter performs (1, 0, 1, 0, 1)/3 filtering with one of the green pixels in the first line as a target pixel, green pixels are multiplied by 1, red pixels are multiplied by 0, and the sum of the pixel values is divided by 3. As a result, a simple average of the target pixel and the adjacent green pixels is calculated. When one of the red pixels in the first line is defined as a target pixel, a simple average of the target pixel and the adjacent red pixels is calculated in the same manner. Similarly, green and blue pixels in the second line are filtered. Every third pixel of the horizontal components is then extracted in a 1/3 horizontal-extraction unit to generate an extracted-pixel group composed of pixels each having the simple-average value of every third pixel as a target pixel and the adjacent pixels of the same color. The present invention is applicable to digital cameras.
