摘要： An image processing apparatus includes a replacement unit and interpolation unit. For the pixel value of a pixel that need not be replaced among pixel values contained in original image data, the replacement unit adds replacement information indicating non-replacement of the pixel value to the pixel value, and outputs the pixel value as replacement information-added image data. For the pixel value of a pixel that needs to be replaced, the replacement unit replaces the pixel value by a predetermined pixel value, adds replacement information indicating replacement of the pixel value to the replaced pixel value, and outputs the pixel value as replacement information-added image data. The interpolation unit outputs interpolated pixel values having all color information by interpolating a pixel value at an interpolation point for each color information on the basis of a predetermined arithmetic expression from the pixel values of pixels of the same color falling within a predetermined interpolation region containing the interpolation point among all replacement information-added image data output from the replacement unit. When replacement information of any pixel used for calculation indicates replacement, the interpolation unit uses an arithmetic expression different from the arithmetic expression.

摘要： An image processing apparatus includes a spatial filter and orthogonal transform section. The spatial filter obtains a new luminance value of each pixel of an input image on the basis of a first coefficient having a first filter characteristic which forms the desired spatial frequency adjustment filter characteristic in cooperation with a second filter characteristic, thereby generating a two-dimensional intermediate image which has the adjusted spatial frequency characteristic of the input image. The orthogonal transform section performs two-dimensional orthogonal transform for the intermediate image on the basis of a second coefficient which has the second filter characteristic, which forms the desired spatial frequency adjustment filter characteristic in cooperation with the first filter characteristic, and is used for two-dimensional orthogonal transform for compressing the intermediate image generated by the spatial filter, thereby generating image data which has the adjusted spatial frequency characteristic of the intermediate image and has undergone two-dimensional orthogonal transform for image compression.

摘要： An image processing apparatus includes an interpolation unit, compensation value calculation unit, and compensation unit. For an interpolation point selected from an image signal at an interval of n pixels (n is an integer of 2 or more), the interpolation unit interpolates the pixel value of each color data at the interpolation point using the pixel values of pixels of the same color falling within an interpolation region of m×m pixels (m is an integer of 2 or more) centered on the interpolation point, and outputs the pixel value as an interpolated pixel value at the interpolation point for each color data. The compensation value calculation unit generates a pixel compensation value for compensating for the pixel value of the interpolation point using the pixel values of pixels falling within a compensation region of M×M pixels (M is an integer equal to or larger than m and n) centered on the interpolation point. The compensation unit compensates for the interpolated pixel value of each color data at the interpolation point that is output from the interpolation unit by using the pixel compensation value corresponding to the interpolation point that is obtained by the compensation value calculation unit, and outputs the compensated pixel value as a new pixel value of each color data at the interpolation point.

摘要： Color correction is performed on a first set of three pixel values by determining a color phase of the pixel values. The determined color phase is used to determine a phase difference, and the phase difference is used to control an amount of color phase rotation applied to the chrominance pixel values of the first set. The color phase is also used to determine a first gain, and the first gain is used to control a scaling of the rotated chrominance pixel values, thereby generating color corrected chrominance pixel values. The color phase is also used to determine a second gain, and the second gain is used to control an amount of scaling applied to the luminance pixel value of the first set, thereby generating the color corrected luminance pixel value. How color phase determines phase difference, the first gain and the second gain is changed depending on lighting conditions.

摘要： In an image processing method, a square submatrix formed from adjacent original pixels is equally divided into small square regions along the X- and Y-coordinate axes. Approximate points are set at the vertexes of the regions. Interpolation coefficients are derived based on a predetermined interpolation function. Interpolation coefficients normalized so as to adjust the sum of the coefficient values of interpolation coefficients used for one interpolation operation to 2k (k is a positive integer) are calculated, and stored in a coefficient buffer in advance. A new pixel position of each pixel constituting a new image is calculated in accordance with magnifications representing enlargement/reduction ratios along the X- and Y-coordinate axes for an original image. An approximate point closest to the new pixel position is selected as the approximate point of the new pixel position. Interpolation coefficients corresponding to the interpolation original pixels are read out from the coefficient buffer. Interpolation operation is performed by product-sum operation, thereby calculating a pixel value at the approximate point. The calculated pixel value is divided by 2k to output a pixel value at the new pixel position. An image processing apparatus is also disclosed.
