Title: Image pickup device
Inventor: ENDO SHOZO
IPC: H04N5/335
Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To eliminate unevenness of the analog signal from an image pickup means in a short time by a simple processing circuit by controlling the gain of the analog signal in the preceding stage of conversion of the analog signal from the image pickup means to a digital signal. SOLUTION: The signal level of an optical signal inputted to an area sensor 1 through a lens 18 is so curved that it is relatively high in the center of the lens 18 and is relatively low in the peripheral part. For the purpose of eliminating the unevenness of the output signal, such gain control signal is outputted from a CPU 12 to gain control amplifiers 14 to 17 so that the downward curved output which has a relatively high level at the time corresponding to the center of the lens 18 and has a relatively low level at the time corresponding to the peripheral part can be obtained. Thus, gains of gain control amplifiers 14 to 17 are controlled. As the result, two signals of opposite levels are cancelled to obtain an ideal fixed-level signal as the output signal of gain control amplifiers 14 to 17.

Abstract: PURPOSE:To make the structure fine and increase the yield without disconnections by a method wherein a low melting point metallic wiring of the upper layer is isolated, and then double-layer wiring is performed by oxidizing only a high melting point metallic film of the lower layer with that wiring as the mask. CONSTITUTION:The high melting point metallic film 3 is formed over the entire surface of a semiconductor substrate provided with an insulation film 2 at the fixed part of its surface, and the low melting point metallic film 4 is formed thereon. Thereafter, the film 4 is etched on the basis of the required electrode wiring pattern 5, and thus the wirings are isolated. Afterwards, only the film 5 exposed between the low melting point metallic electrode wirings is oxidized at a low temperature whereby the film 4 is hardly oxidized, and only the film 5 is oxidized, thus forming a fine structure of double layer electrode wiring consisting of the film 4 of the upper layer and the film 5 of the lower layer.

IPC: G06F5/00
Filed: 1992-08-03
Abstract: PURPOSE:To decode a bit variable length code at high speed by deciding a shift amount at the low-order part of data read from a variable length decoding table in the case of decoding end by using a shift control circuit. CONSTITUTION:Assuming that an initial address set to a start address register 101 is described in the same format as that of a variable length decoding table 103a, the initial address is passed through a multiplexer 105 later, and the least significant four bits are replaced with the leading four bits of a shift register 107 storing data to be decoded. Before that replacement, a multiplexer 111 for sub block address is used for designating the range of the replacement, and an inverter 108a is used. Namely, when the least significant field two bits of an output from the multiplexer 105 are '01', the replacement of the least significant two bits is generated. Namely, the central field two bits of the output from the multiplexer 105 are turned to the output of the multiplexer by ignoring the leading two bits of the inverter 108a.

Abstract: PURPOSE:To obtain a potential contrast image at a high speed and to prevent the accumulation of electric charge by temporarily keeping the state wherein a certain test pattern is inputted, and obtaining the potential contrast at the state wherein the time is made longer than the input time of another test pattern. CONSTITUTION:The length of a pattern (i-th clock) wherein a potential contrast image 10 is to be obtained is made longer than another pattern. The rate of a pattern-applying time with respect to the applying time of the entire pattern is increased. Therefore, the signal to noise ratio is improved. The pattern is not kept for a long time but the pattern is temporarily kept so that the accumulation of electric charge does not occur. The keeping time is limited within about one second, and the entire pattern is repeated. In this method, the potential contrast image can be obtained at a high speed, and the potential contrast due to the accumulation of the electric charge is not deteriorated.
