摘要： PROBLEM TO BE SOLVED: To provide an image processor for correcting deterioration due to influence of a color boundary.SOLUTION: A color boundary extracting section 11 extracts the color boundary of an image. An influence value calculating section 12 calculates an influence value showing a size of influence which the color boundary exerts on a pixel. A coefficient setting section 13 sets a pixel being an object of a convolution operation as a target pixel in an operation section 14, and sets a coefficient for the convolution operation corresponding to the pixel in a region separated by the color boundary including the target pixel to be smaller as the influence value is larger and to be larger as the influence value is smaller. The operation section 14 divides the coefficient which is set by the coefficient setting section 13 by a total sum of the coefficients to normalize the coefficient, and performs the convolution operation by using the normalized coefficient.

摘要： PROBLEM TO BE SOLVED: To improve image quality by suitably performing image processing on image data of content in which images and characters coexist in a mixed manner.SOLUTION: On the basis of input image data, an image processing device acquires band information of each of a plurality of blocks into which a screen is divided. On the basis of band information of each block, the device classifies the screen into a plurality of types of areas such as an image area, a character area, and a mixed area of images and characters. The device calculates processing strength for each classified screen area. Then, the device performs predetermined image processing, such as sharpness processing, on the input image data for each classified screen area at the calculated processing strength. Thus, it is possible to prevent degradation of image quality because image processing has been performed on the image area and the character area at the same processing strength.

摘要： The present invention relates to an image processing device and method, program and recording medium for achieving grayscale compression capable of suppressing image quality degradation using a simple configuration. A detection section 63 performs a detection process of a signal Y' that has been subjected to the processes of a luminance signal generating section 61 and perception equalization section 62, thus finding average intensities of lighting in bright and dark areas of an input image. A control MPU 64 finds adaptation gains kAr and kBr based on the average intensities. Processing the signal Y' with an edge-preserving LPF 65 provides a lighting component signal Y'lp. A detail extraction section 66 computes the difference between the signal Y' and lighting component signal Y'lp, thus extracting a detail component signal Y'de of the image of the signal Y'. Thereafter, the lighting component of the signal Y' is subjected to grayscale compression by a tone curve process section 68, while the detail component of the image of the signal Y' is subjected to grayscale compression by a detail adjustment section 67.

摘要： PROBLEM TO BE SOLVED: To perform interpolation processing not limited to an edge direction.SOLUTION: Most adjacent actual pixels GG1-GG4 are specified with respect to a target interpolation pixel HG. When an edge type is given, a division region to which the interpolation pixel HG belongs is specified by the edge type. A normal is defined from the interpolation pixel HG on a division line constituting the division region belonging thereto. Intersections are used as a virtual position, and pixel values of the virtual positions 1 and 2 are operated by weighted average operation using a distance. A pixel value HGP of the interpolation pixel HG is operated from pixel values of virtual positions P1 and P2. Thus, a pixel value of the interpolation pixel HG is obtained on the basis of pixel values of vertex pixels G22, G23, G36, and G35 constituting a parallelogram.
