Abstract: An image joining apparatus includes: a motion vector detection unit that detects a motion vector between images; a motion compensating unit that performs correction of compensating for a positional difference value between the images on one of the images using the motion vector to generate a motion compensated image; a difference determination unit that selects one of the images and determines whether a difference value between adjacent pixels in the selected image is equal to or larger than a value; an overwriting unit that overwrites another image with the selected image in an area of the selected image in which the difference value between the adjacent pixels is equal to or larger than the value; and a mixing unit that locally mixes the selected image and the other image in an area of the selected image in which the difference value between the adjacent pixels is smaller than the value.

Abstract: A saturation ratio calculation unit calculates a saturation ratio of the saturation of an outer circumference of a color gamut of an input image to the saturation of an outer circumference of a color gamut of an output image. A histogram generation unit generates a histogram in which a plurality of pixels selected as pixels outside the color gamut are counted for each pair of lightness and hue. A magnification determination unit determines, within a range of not less than 1 and not more than the saturation ratio, a magnification by which the chromaticity of the input image to be subjected to the color gamut conversion is to be multiplied for each pair of lightness and hue based on the histogram.

Abstract: A peripheral blown-out pixel counter counts the number of blown-out pixels in a block including a target pixel and peripheral pixels in image data. A G threshold setting unit sets a G threshold such that the G threshold is greater as the number of the blown-out pixels is larger. A (B−G) threshold setting unit sets a (B−G) threshold such that the (B−G) threshold is smaller as the number of the blown-out pixels is larger. A correction necessity determination unit determines that a color of the target pixel should be corrected when a G signal is determined to be smaller than the G threshold and a (B−G) value is determined to be greater than the (B−G) threshold. A color correction unit corrects at least the G signal and a B signal when the color of the target pixel should be corrected.

Abstract: An image processing method is provided. Calculating sums of differences identified between a pixel value of a pixel of interest in an input image and pixel values of three pixels surrounding the pixel of interest. Calculating an average value of four pixel difference sums calculated by the pixel difference sum calculators. Calculating deviations between the average value and the four pixel difference sums calculated by the pixel difference sum calculators. Deriving a minimum coefficient from the candidates of coefficient calculated by a candidate coefficient calculator by using adjusted deviations derived from multiplying the deviations by a constant. Subtracting values derived from multiplying the adjusted deviations by the minimum coefficient from the pixel value of the pixel of interest in the input image and outputting values of four pixels in an enlarged image twice an original size of the input image in horizontal and vertical directions.
