Title: Method and device for quantizing gray level
Inventor: MOOZEN GAADERI
IPC: G06V30/162
Filed: 1992-09-04
Abstract: PURPOSE: To improve contrast, while maintaining a resolution level. CONSTITUTION: When a quantizer 22 of an image-processing system 10 scans the entire images, a background level is roughly decided so as to be almost equal to the average value of all input data less than a certain fixed round-down level. The quantizer 22 uses the value as a lowest quantization threshold value. The quantizer 22 decides a remaining quantization threshold value by using a value identified as being almost equal to the center of the range of the value of a most interesting pixel in the images, corresponding to a reference based on the certain kinds of fluctuation. By this method, while the contrast desirable for the images of a text type is obtained, the resolving power of the system is turned to an area, where most valuable information is present.

Title: Semiconductor integrated circuit
Inventor: ISHIDA HIROSHI
IPC: H03K17/687
Filed: 1987-09-24
Abstract: PURPOSE:To directly apply the high voltage to an internal circuit part and to ensure an effective test of the aging, etc., by performing the selective switch between a state where the external voltage is dropped and supplied to the internal circuit and a state where the external power supply voltage is supplied directly to the internal circuit. CONSTITUTION:A 5V power supply is used to a semiconductor integrated circuit and at the same time a power supply less than 5V is used to an internal circuit (not shown in figure). In a floating state of an external control electrode Pc, the MOSFET Q2 and Q3 are turned on and a resistance element R1 and a Zener diode ZD is shunted between a pair of external power supply terminals Vdd0 and Vss0. Thus the normal drive voltage is obtained at the internal circuit between a pair of internal power supply terminals Vddi and Vssi. When a ground potential is supplied to the electrode Pc, both FET Q2 ad Q3 are turned off and the constant voltage action carried out by the diode ZD is stopped. Thus the potential of the terminal Vddi is set approximately equal to the potential of the terminal Vdd0 via a MOSFET kept turned on.

Abstract: PURPOSE:To contrive better gradation expression of image density, by a method wherein an acicular crystalline filler is incorporated in a transfer layer in a specified amount based on the amount of a leuco dye, which is present in a particulate state. CONSTITUTION:The thermal transfer medium comprises a transfer sheet having a transfer layer comprising a leuco dye and a receiving sheet having a receiving layer comprising a color developer for the dye. Acicular crystals of the filler incorporated in the transfer layer assumes a network structure with the major crystal axis thereof in parallel with the surface of a base, are firmly bound to the base, and hold the fine particles of the leuco dye in voids in the network structure. A leuco dye ink melted in thermal printing exudes from the network structure onto the surface of the receiving sheet, little by little. By controlling thermal energy, the color development quantity of a developed color image formed on the receiving sheet is varied, resulting in an image with excellent gradation property. The amount of the filler used is at least 0.5pts.wt. per 1pts.wt. of the dye. If the amount of the filler is excessively small, the force for holding the dye is weak, and gradated images can not be obtained.
