Abstract: An image processing method according to the present invention is contrived to change the gradation level (of the color component corresponding to the complementary color of yellow) for a pixel within a zone located on a corner of a rectangular image so as to maximize the difference between the gradation level of a pixel that is a processing target and the gradation level of a pixel in a background area in the surrounding area of the pixel that is the processing target, that is, lowering the gradation level. This means the pixel that is a result of applying the process for changing the gradation levels looks yellowish. The human eye has difficulty in recognizing yellow and therefore the change applied to the pixel is inconspicuous as compared to the case of placing a mark or frame on the outside of a rectangular zone.

Abstract: When an input-output request for file management information is inputted to a file management information storage apparatus, the input-output request is accepted by a file management section. A fixed-length area management section then inputs and outputs basic management information for managing a file corresponding to the input-output request to and from a fixed-length area of a storage unit as fixed-length data. In addition, a variable-length area management section inputs and outputs extended management information for managing the file corresponding to the input-output request to and from a variable-length area of the storage unit as variable-length data.

Abstract: First, the original data C is divided into an n number of pieces of partial data C1-Cn. Then pieces of position information P1-Pn are added to those pieces of divided partial data, and they are respectively embedded into the n number of duplicated images. Then, the resultant images E1-En are produced. The resultant images are displayed in the same position on a display screen as a still image for T1 seconds each. In a camera of a mobile phone, etc., the displayed images are repeatedly photographed at an interval of T2 seconds that is shorter than T1 seconds, and the pieces partial data C1-Cn and position information P1-Pn are sequentially extracted. When all the processes are completed, the pieces of partial data are integrated on the basis of the pieces of position information P1-Pn. As a result, the original data is obtained.

Abstract: Using an image region detection method according to the present invention, the detection of sides in the four directions (vertical and horizontal directions) is performed on the basis of results of edge detection performed on lines having a particular width, starting from an inner point toward the periphery of the quadrangular region in an input image, and the shape and the four corners of the quadrangle formed by the detected four sides are verified. Thereby, when there is a side that has been falsely detected, redetection on sides that are closer to the periphery than the side that has been detected falsely is performed, such that the quadrangular region can be formed at high speed.
