Title: Solid-state image pickup device
Inventor: MATSUDA HIDEAKI
IPC: H04N5/369
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To reduce number of manufacture processing stages and to allow the image pickup device to pick up correctly an image of an object. SOLUTION: A middle part of a picture element area 1 is a valid picture element area 3 of a light receiving section and its outer circumferential parts are an OB(optical black) area 4. Each valid picture element 2A applies photoelectric conversion to an incident light into an image signal. On the other hand, A signal read from an OB part picture element 2B is a signal not corresponding to the incident light. A separate light shield picture element 10 is formed to a position other than the picture element area 1 and a metallic light shield film 11 for the separate light shield picture element is formed on the surface of the picture element 10. When a read circuit 6 reads a signal of the OB part picture element 2B, a changeover switch 13 is thrown to the position of an S/H circuit 12, from which a reference signal is outputted.  On the other hand, when the read circuit 6 reads an image signal from the valid picture elements 2A, the changeover switch 13 is thrown to the position of the read circuit 6, and the image signal is outputted through the changeover switch 13.

Inventor: YAMADA SHIGERU
IPC: G06K9/20
Filed: 1995-03-02
Abstract: PURPOSE: To increase the luminance of a character part by arranging the optical axis of a lighting device so that it crosses a direction of orientation, i.e., length direction at right angles. CONSTITUTION: As shown in (b), the character part 4 is formed of a repetitive pattern of unevenness (white and black correspond to a recessed and a projection part respectively) having an orientation direction fixed. An arrow 17 in the figure indicates the direction of lighting by the lighting device 7 in a figure (a). The lighting device 7 is so arranged that the character part 4 is lighted up as shown by the arrow 17, namely, in the orientation direction of the unevenness, i.e., in a direction crossing the length direction at right angles, and then irregular reflection is caused at edges of the unevenness of the character part 4, so that an image can be picked up even when the character part is transparent.  Thus, the optical axis 8 of the lighting optical system is arranged at right angles to the length direction and then since the luminance of the character part 4 is made high, even characters of high transmissivity which are engraved on the glass substrate of a liquid crystal display body can clearly be recognized.

Abstract: PURPOSE:To improve the breakdown strength by avoiding the overlapping, with the electrode metal, of a part which may become an emitter stabilizing resistance, and maintaining resistance value established by the geometrical size of polysilicon, thereby avoiding the local current concentration. CONSTITUTION:An emitter stabilizing resistance 4 is in contact with an emitter region 1 in two points a, b where a silicon oxide film 3 on the emitter region 1 was removed, and in contact with an electrode metal 6 in a part c where an inter-layer insulating layer 5 on the emitter stabilizing resistance 4 was removed.
