Abstract: The present invention provides a new customizable folio system that is useful for presenting selectable optical characteristics to one face of a folio cover. The selectable optical characteristics are presented at one face of the folio cover as the result of selective replacement of insert sheet(s) that are placed into a pocket formed between the outer folio cover sheet and an inner backing sheet. Either the outer front face of the folio cover, or the inner backing sheet has at least one cutout section(s) therein, of any desired shape or design, through which selective part(s) of the insert sheet(s) can be viewed. The insert sheet(s) have optical characteristic(s) that are different from those of either the outer front face of the folio cover or the inner backing sheet, at least in those areas of the insert sheet that can be seen through the cutout section(s).

Abstract: In order to display an image on a liquid crystal display at a constant image quality independently of a change of the length of the period for applying voltages with the same polarity to the liquid crystal, the length of one cycle of a horizontal synchronizing signal inputted to an LCD unit from an information processor is counted and the amplitude of data voltage and the center of the amplitude are corrected so that the amplitude of the data voltage to be applied to the liquid crystal increases and a correction value for the center of the amplitude increases as the length of the period for applying data voltages with the same polarity to the liquid crystal decreases in accordance with the length of one cycle of the horizontal synchronizing signal and whether to perform gate overlap scan.

Abstract: The stretching of bitmap images in a computer system is accomplished by stretching each row of a source bitmap and storing the pixel information associated with the stretched row in a buffer, typically in main memory. The pixel information is transferred multiple times to the memory location associated with the destination bitmap, these memory locations generally reside in either main memory or in the frame buffer. Each time the buffer is written to the destination bitmap, an error term is adjusted by a predetermined amount. When the value of the error term meets a predefined criteria, the next row of the source bitmap is stretched and stored in the buffer and the process is repeated.
