  • Patent number: 7920756
    Abstract: A printer fetches a horizontal direction DCT coefficient group and a vertical direction DCT coefficient group for each block from the JPEG data. The printer selects edge patterns similar to the brightness changes expressed by these coefficient groups from a specified table, and records those pattern numbers in a RAM. The printer judges whether or not the brightness changes of the blocks with each other adjacent are continuous based on the pattern number of each block recorded in the RAM. And by connecting the edge patterns when those brightness changes are continuous, the printer accumulates the blur widths that exist extending over the blocks. Then, based on this cumulative value, the printer determines the presence or absence of image blur. It is possible thereby to detect with good precision the blur of images even for high resolution images while reducing the used memory capacity.

  • Publication number: 20090208114
    Abstract: An image processing apparatus that selects at least one photo image out of a plurality of photo images. A face area determining unit detects whether or not there is a face in each photo image and determines a face area of the face, if any, detected in each photo image. An image evaluation processing unit calculates a first edge amount pertaining to the face area detected in each photo image. An image selecting unit selects a photo image from among the plurality of photo images on the basis of the first edge amount of each photo image.

  • Publication number: 20070247662
    Abstract: An image processing apparatus for printing includes an analysis unit, a correction unit, a print-data generating unit, and a storage unit. When first analysis data corresponding to target image data has been generated, the analysis unit does not perform analysis processing on the target image data. When first analysis data corresponding to the target image data has not been generated, the analysis unit performs analysis processing on the target image data and generates second analysis data. The correction unit corrects the target image data using the first or second analysis data corresponding to the target image data and generates corrected image data. The print-data generating unit generates print data using the corrected image data. The storage unit stores the second analysis data in association with the corresponding target image data.
