Abstract
Disclosed is an image signal processing apparatus in which the position of an input image can be corrected easily irrespective of the shape of the input image by use of attribute information obtained from image information. Image information read by an image information reading unit is stored in an image information storage unit, and rectangular blocks are extracted sequentially from the image information by a block extracting unit. Shapes of images in the extracted blocks are analyzed by a block shape analyzing unit, and the analyzed block shapes are stored in a block shape storage unit. An image signal from the image information storage unit is displayed on an image signal display unit, and the analyzed block shapes from the block shape storage unit are displayed on another display unit. Instructions on position are given on the image signal display unit by a position instruction unit along the shape analysis result of image signals in the positions corresponding to the extracted blocks, to thereby correct the inclination of the input image signal.
