摘要： A detection apparatus includes an image sensing device having an image sensing plane including a first periodic structure; and an optical system configured to illuminate a detection target including a second periodic structure different from the first periodic structure, and form an image of light from the detection target on the image sensing plane. Light having entered the image sensing plane generates a plurality of diffracted light beams of different orders in accordance with the first periodic structure. A normal of the image sensing plane is tilted with respect to an optical axis of the optical system such that the optical axis is located between diffracted light beams of adjacent orders not less than a first order among the plurality of diffracted light beams.

摘要： The method adjusts an output image area for producing an output image from a recorded area of an original image within the recorded area of the original image so as to produce output image data that complies with a predetermined output image size. The method extracts the recorded area of the original image, extracts at least one region of a principal subject, a finger image and a fog region from the extracted recorded area of the original image to obtain an extracted region. The method adjusts the output image area automatically in accordance with the extracted region and obtains output image data from the image data in the adjusted output image area. Alternatively, the method issues information for urging an adjustment of the output image area when it is determined as a result of the extracted region that the adjustment of the output image area is necessary.

摘要： The present invention provides a color image processing system for processing drawings at high speed while reproducing color tone with fidelity. The color image processing system includes a digital processor that performs a raster operation on multigradation image data and generates an output image represented by a first plurality of color components. The system also includes a processor which separates the output image data into a second plurality of color components and stores the separated data in a memory. The system includes a reverse color separator which transforms the stored image data back into image data represented by the first plurality of color components and supplies this transformed image data to the digital processor. In a preferred embodiment, the digital processor performs an under color removal/black generation conversion to separate the output image data resulting from the raster operation into cyan, magenta, yellow and black color components. The reverse color separator performs a reverse under color removal/black generation conversion to restore the stored image data to a cyan, magenta, yellow format suitable for use by the digital processor.
