Title: Filter method
Inventor: YOKOYAMA MIGAKU
IPC: G06T15/08
Filed: 1994-09-22
Abstract: PURPOSE: To perform no filter process when the result of a filter process is already known before calculation by calculating an output area from the position of a given output position when the values of the position of an input point and the position of an output point, and dividing the calculated output area into areas for the filter process and an initializing process. CONSTITUTION: The area where the input point exist is calculated from the position of the input point (S11) and the area where the output point is present is calculated (S12). Then, an input data generation area is calculated by adding filter width to the calculated input area (S13). Then, the calculated output area is divided into the area (S17) for which the filter process is to be performed and the area (S18) for which the initialization is to be performed (S18). The filter process and initialization are performed for the output points in those areas. Consequently, when the result of the filter process is known before the calculation, the filter process is not performed to shorten the process time.

Filed: 1994-08-30
Abstract: PURPOSE: To reproduce a red character and a red image well by providing a colored filter cutting a red light beam on an optical path from an illuminating system to a photoreceptor. CONSTITUTION: Light beam irradiated on an original 1 and is reflected is condensed through condensing optical fiber 7, and is transmitted through a red color cutting filter 8 adhered to the lower end face of the fiber 7, and when it is projected on a photoreceptor 9, a charge on the photoreceptor 9 is destaticized in accordance with the intensity of the light reflected from the original 1, and an electrostatic latent image corresponding to an original image is formed. Since the red components of the light reflected from the red character and the red image are mostly cut by the filter 8 when the character and the image written by red color exist on the white surface of the original 1, the difference between the electric potential of the electrostatic image formed on the photoreceptor and the electric potential formed by the light reflected from the white surface becomes large.  As a result, the reproducibility of the red character and the red image is improved.
