A micro-mirror unit of data from a plot point formation element unit data to a plot unit of frame data. A micro-mirror unit of data to be sequentially supplied to a plurality of micro-mirrors is produced from an image data corresponding to an image to be formed in a plot screen by use of DMDs each having the plurality of micro-mirrors. An intermediate data is then produced by extracting data change points of the produced micro-mirror unit of data. The data is inverted for each of the data change points in the produced intermediate data, thereby performing the transportation from the micro-mirror unit of data to the DMD unit of frame data.

A dot analysis apparatus includes a dot converging section that converges individual dots forming a dot image toward their respective centers, a selecting section that selects plural dot units each consisting of one main dot and plural sub-dots surrounding the main dot from the converged dots, a calculating section that calculates an interval between the main dot and the sub-dots of each dot unit and a direction of arrangement of the main dot and the sub-dots, and a statistic processing section that determines statistic distributions of the interval and the direction calculated for each dot unit by the calculating section and determines the interval and the direction corresponding to the peaks of their respective distributions as the interval between the regularly arranged dots forming the dot image and the direction of the regular arrangement of the dots forming the dot image, respectively.

A position in runlength compression data corresponding to a desired position in original data can be found fast. Index correspondence information is generated for representing correspondence between indexes representing predetermined positions in data arrangement of the original data having a plurality of values and positions corresponding thereto in the runlength compression data. The index closest to the desired position in the original data and an offset of the desired position from the index are found. Based on the index correspondence information, the corresponding index in the runlength compression data is found. The position corresponding to the desired position is then found in the runlength compression data, based on the corresponding index and the offset.

Method and apparatus for position identification in runlength compression data

An image input apparatus receives image data from a scanner having a reading surface on which an original image is placed, the image data being generated through reading the reading surface. An image outline determination apparatus determines an outline of an original image placed on the reading surface of the scanner in accordance with the image data obtained by the scanner. An area designation section designates a rectangular proposed area of which at least portion enters into an area of the original image placed on the reading surface. An outline determination section determines the outline of the original image by repeating a plurality of number of times an area alteration processing in which a movement of sides defining an outline of the proposed area outside or inside the proposed area is determined in accordance with differential or difference of image data for vicinity of the sides, and the proposed area is altered in accordance with a decision of the movement, wherein the area alteration processing is repeated taking an area after the proposed area is altered as a new proposed area.
