| 20090086229 | Image Processing Device and Pixel Attribute Identification Method - The printer of the invention performs an area classification process to classify each pixel included in an input image read by a scanner as a pixel in an edge component area or a pixel in a halftone dot area, and performs a correction process with a spatial filter suitable for each area. The area classification process calculates a difference value between luminance values of two arbitrary pixels selected among peripheral pixels in a specific pixel range around each target pixel according to each of multiple differential patterns t, compares the calculated difference value with threshold values provided for each differential pattern t to compute multiple difference detection values ht(x) corresponding to the multiple differential patterns t, and gives weights to the computed difference detection values ht(x) to compute a comprehensive difference detection value H(x). The area classification process identifies whether the target pixel is a pixel in the edge component area or a pixel in the halftone dot area, based on the computed comprehensive difference detection value H(x). This arrangement enables high-speed identification of the attribute of each pixel included in an image by such simple operation, while enabling identification of pixel attribute with high accuracy. | 04-02-2009 |
| 20090091809 | Image Processing Device, Method and Program Product - First integrated data is generated using tone value data. The tone value data represents respective tone values of pixels of an image. The first integrated data represents respective first pixel values of the pixels. The first pixel value is associated with sum of tone values of pixels within a rectangle in the image. The rectangle has two opposing corners represented by a pixel corresponding to the first pixel value and a reference pixel respectively. The reference pixel is a pixel at a predetermined corner of the image. A calculation process is executed. The calculation process includes calculation of a first calculation value of a target rectangle area using the first integrated data. The first calculation value is correlated to sum of tone values within the target rectangle area. The target rectangle area is enclosed by a rectangle defined by pixel boundary lines. The pixel boundary lines represent boundary lines between neighboring pixels in the image. Image processing in relation to the target rectangle area is executed in accordance with the result of the calculation process. In the calculation of the first calculation value, the first calculation value is calculated using respective first pixel values of four calculation pixels. The four calculation pixels are respectively adjacent to four vertexes of the target rectangle area in the direction of the reference pixel. The four vertexes are on the pixel boundary lines. | 04-09-2009 |
