Abstract: In a first correction process, a correction value T(0) is set as a median value between minimum and maximum correction values Tmin(0) and Tmax(0). A provisional adjustment value B=T(0)+Bini is input to the circuit section. A signal value output from the circuit section in accordance with the provisional adjustment value B is obtained by an A/D converter, and the magnitude relationship between the signal value and a target value is determined. When the signal value is smaller than the target value, a value that is smaller than the correction value T(0) by an error tolerance is set as a new minimum correction value Tmin(1). The median value between the minimum correction value Tmin(1) and the maximum correction value Tmax(1)=Tmax(0) is set as a next correction value T(1). In the next correction process, the provisional adjustment value B=T(1)+Bini is input to the circuit section.

Abstract: The present invention provides stereoscopic prints with reduced image coarseness. A stereoscopic print comprises a lenticular lens sheet and a dot image print that is glued to the back surface of the lenticular lens sheet. Multiple image strips that form the dot image print each include a small unit that enables tone representation, and for each color plate, multiple reference positions are set in each of the smallest units. In forming the dot image print, amplitude-modulated screening is employed to print dots in longitudinal directions of the multiple image strips from each of the reference positions.

Abstract: The present invention provides stereoscopic prints with enhanced resolution and reduced image coarseness. A stereoscopic print comprises a lenticular lens sheet and a dot image print that is glued to the back surface of the lenticular lens sheet. The order of printing dots for the pixels of tone-representing smallest units with the use of a color plate is set at random. The dot printing order is the same among a given number of image strips forming an image strip group that are continuously arranged in a direction perpendicular to a longitudinal direction of half-cylindrical lenses so that dot printing is performed continuously on an area in which pixels to be printed are continuous.

Abstract: The present invention is directed to a method for recognizing and classifying one or more unknown patterns, such as letters or numerals, by comparing these unknown patterns to a set of reference patterns. The unknown patterns, as well as the reference patterns, are irradiated by a coherent or incoherent beam, and correlation outputs are measured which would be at peak value of an auto-correlation output or a cross-correlation output between the unknown patterns and the reference patterns. Membership functions are created for each of the reference patterns, and a membership value is estimated or calculated on the basis of the output correlation between the unknown patterns and the reference patterns. Based upon this membership value, the specific unknown pattern is determined.

Abstract: An image memory controller having a first address signal generating unit generating a first address signal in response to a state signal representing the operational state of a printer. The first address signal corresponds to a location in an image memory. A second address signal generating unit generates a second address signal for refreshing the image memory and a third address signal generating unit generates a third address signal used for rewriting at least part of data stored in the image memory. An address signal selector selectively delivers any of the first, second, and third address signals to the image memory.
