Abstract: There is proposed is a method of controlling a flat panel display apparatus for multi-gradation display in which a data determination portion and a subfield control portion are provided. Based on a most significant bit or an upper bit of original image data, it is determined in which one of two or more divided gradation groups the original image data is included, to select a combination of subfields in accordance with a gradation-brightness characteristic of the belonging gradation group. Using a complementary relationship with human visibility, a difference in brightness between the gradations in a low-order brightness region is reduced, and a difference in brightness between the gradations in a high-order brightness region is enlarged. Therefore, a density of brightness is uniformly recognized visually over all the brightness regions, and a good quality of display can be obtained.

Abstract: Data latch circuits are provided corresponding to select memory cells from or into which read or program is executed. The data latch circuits are grouped by two into sets. When 2-bit data is read from or programmed into the select memory cells, one data latch circuit is selected by a select signal, and, when 1-bit data is read or programmed, the two data latch circuits in one set are selected by a select signal. Between one or two selected data latch circuits and a data input/output buffer, data is exchanged. By so doing, changeover between 2-level data and multi-level (4-level or more-level) data concerning program or read of data into or out the memory cells becomes possible.
Abstract: An image processing apparatus detects, in step 1, whether or not differences between currently supplied image data and image data of a previous pixel are more than a predetermined value m, and identifies a border of a computer-created image or a natural image, where a brightness level differs from the remaining area of the image, when the differences are more than the predetermined value m. Conversely, when the differences are less than the predetermined value m, the image processing apparatus checks, in step 2, whether image data at a pixel before and a pixel two before the current pixel are identical with respect to the color components constituting the color image. When the differences are not all zero, it is checked whether or not the image data at a pixel before the current pixel and the image data at the current pixel are all zero. When the image data are not identical, the color image is identified as being a natural image.

A cover hinged to the frame is movable between an open position and a closed position. An elastomeric platen roller is rotatably supported by the cover, the thermal print head and the platen roller being relatively resiliently biased toward each other to urge the printing elements carried by the thermal print head into contact with a recording medium disposed between the thermal print head and the platen roller when the cover is in the closed position.
Abstract: There are provided a printing method of printing an image of characters, figures or the like on a plate-making surface of a plate-making sheet, and an apparatus therefor. The apparatus feeds a plate-making sheet by a predetermined amount assigned to a forward end of the plate-making sheet when the forward end is detected by a sensor. When a mark for detection provided on the plate-making sheet is detected during the feeding of the plate-making sheet by the predetermined amount assigned to the forward end, the apparatus further feeds the plate-making sheet by a predetermined amount from a position of the plate-making sheet where the mark for detection is detected, to thereby locate the start of an image-forming area of the plate-making sheet. On the other hand, when the mark for detection is not detected, the apparatus continues feeding of the plate-making sheet.
Abstract: A differential amplifier (24) includes a pair of transistors (Q2 and Q9); a differential amplifier 25 includes a pair of transistors (Q3 and Q6). A difference in output currents at the differential amplifier (24) is detected by differential amplifier (25).

The obtained voltages at the both terminals of the capacitor (26) are fed back to the input of the differential amplifier (24) via transistors (Q1 and Q8), so that offsets at inputs of the differential amplifier (24) are corrected.

In the erase operation, PVOK, EVOK and LCKOK are all set to "0" and memory cells are sequentially selected by the internal address of the address counter. That is, each of the memory cells selected by the internal address is subjected to the pre-program, erase and convergence operations.
