Abstract: PROBLEM TO BE SOLVED: To provide a method for displaying much polygon data in real time by more quickly compressing the coordinate data of a polygon. SOLUTION: A CPU 100 stores a coordinate data string expressing the shape of a graphic in a main memory 102. A data compression controller 122 analyzes coordinate data, compares the numerical value of an element of respective converted coordinate data with a numerical value of a new element by the unit of data expressed in a form of floating point, and when both the numerical values of the converted element and the new element are equal, coding information indicating the equality state is generated and outputted. When both the values are different from each other, coding information consisting of the combination of a code indicating the inequality and a code expressing the numerical value of a new element is generated and outputted.  The outputted coding information is decoded to the original coordinate data by a data expansion controller 124 and displayed on a display by graphics hardware (110 to 120).

Title: Electrophotographic printing device
Inventor: SAKURAI TOSHIO
IPC: H04N1/04
Filed: 1991-11-29
Abstract: PURPOSE:To make a pitch irregularity in a subscanning direction due to an irregularity in the rotation of a photosensitive drum inconspicuous by slightly shifting image formation lines in the circumferential direction of the photosensitive drum and forming an image of a gathering of lines which are finely displaced. CONSTITUTION:A lens support plate 19 is held by a spring 21 and a piezoelectric element 22 while having a fulcrum 20. An image forming lens 6 is fixed on the support plate 19, so the optical axis of the image forming lens 6 has a swing and tilt angle as a result of the inclination of the support plate 19. When a control voltage is applied to the piezoelectric element 22 from a control part, the optical axis of the image forming lens 6 slants. Consequently, the irradiation direction of laser light is bent by the image forming lens 6 by a quantity proportional to the swing and tilt of the image forming lens 6. The control part controls the piezoelectric element 22 according to a random signal represented by a white noise. Consequently, random displacement in a subscanning direction is added to the laser light main scanning of the photosensitive drum 9.
