摘要： An image processor which corrects tilt of an input image without operator intervention. Projections of two partial images of an original are obtained at check points determined from input image information. A tilt angle of the original is obtained from a correction position of the projections of each partial area. The image is divided into belt-shaped small areas and shifted in accordance with the obtained tilt angle to form an image in which the tilt of the input image is corrected.

摘要： The present invention is aimed at appropriately suppressing display failure such as a tailing phenomenon and the like in a normally white type liquid crystal panel. A driver (3) supplies a drive voltage in conformity with an image signal received by an image signal processing circuit (1), to a liquid crystal panel (4). A histogram detector (5) detects a histogram representing the relationship between the signal level of the image signal received by the image signal processing circuit (1) and the number of pixels. A CPU (6) calculates, based on the histogram detected by the histogram detector (5), a first proportion of the number of pixels (on the white side) whose signal level is equal to or greater than a first defined value, to the total number of pixels of the histogram and a second proportion of the number of pixels (on the black side) whose signal level is equal to or smaller than a second defined value that is smaller than the first defined value, to the total number of pixels of the histogram. An amplifier (2) corrects the lower limit of the drive voltage that the driver (3) supplies to the liquid crystal panel (4) in accordance with the first proportion of white side pixels and second proportion of black side pixels calculated by CPU (6).

摘要： An optical writing control device includes: a light emission control unit which controls light emission of multiple light sources for respective different colors and exposes multiple image carriers; and a correction amount calculating unit which calculates a correction amount for each of the different colors on the basis of a difference between a central value of a distribution range of positional deviation amounts in a sub-scanning direction for the respective different colors and the positional deviation amount for a corresponding color. The light emission control unit delays light emitting timing of a light source, which is to be delayed, by delaying reading timing of pixel information stored in a storage medium, and delays timing at which the pixel information about colors other than a color, light emitting timing of a light source for which is to be advanced, starts to be obtained from an image forming apparatus main body.
