Abstract: PURPOSE:To stably obtain high-grade images even with recording media of any kinds and characteristics by changing the computation algorithm to convert image signals to recording signals of respective hues according to the characteristics and kinds of the recording media. CONSTITUTION:The input image signals of red (R), green (G) and blue (B) are converted to the density signals (C0, M0, Y0) by a cyan/magenta/ yellow(CMY) conversion circuit 31.

The density of the BK signal is determined in accordance with the min. value of the density signals C0, M0, Y0 and a medium signal PS by the UCR computing device 32. The medium signal PS is the output obtd. by an optical sensor which detects the transparency or translucency of the recording medium right after emission from a paper tray. The output characteristics are switched by the medium signal PS in such a manner and, therefore, the recording images having a good grade are obtd. at all times even if the kinds and characteristics of the recording media vary.

Title: Picture signal processor
Inventor: ENDO KENJIRO
IPC: H04N19/895
Filed: 1987-12-26
Abstract: PURPOSE:To maintain a picture signal with high definition even when an interpolation processing is applied by forming the luminance signal of a picture sample as a high-order symbol, and the chrominance signal of the picture sample as a low-order symbol. CONSTITUTION:A sample word is constituted of 16 bits, and is divided into high-order 8 bits and low-order 8 bits, and the luminance signal Y is allocated to the high-order symbol and the chrominance signal C to the low-order symbol. Therefore, the luminance signal with sensible visibility is arranged to the high- order symbol (8 bits) of a word of 16 bits, and the chrominance signal with low visual sensitivity to the low-order symbol (8 bits). Therefore, in case of performing a corrective arithmetic operation, an interpolation signal can be obtained with at least accuracy of 7 bits from the luminance signal even when a carry is generated from a low-order. In such a way, it is possible to prevent fatal error data from being generated in the chrominance signal even by performing the interpolation processing, and an image with high definition can be obtained.

Filed: 1987-12-26
Abstract: PURPOSE:To seal an integrated circuit tightly, by dropping a molten potting resin from an upper part of a sealing part after a pan abuts against a lower surface of the sealing part and removing the pan after the potting resin becomes solid. CONSTITUTION:When a pan 4 where a potting resin 5a is put in abuts on a lower surface of a sealing part 3, the potting resin is in contact with lower surfaces of lead pieces 11-15, and comes to a state where it enters into the corner parts of lower surfaces of bonding wires 2a through gaps between the lower surfaces of lead pieces and the sealing part.
