Title: Semiconductor sensor
Inventor: UEDA YUTAKA
IPC: H04N5/335
Filed: 1991-10-04
Abstract: PURPOSE:To obtain a semiconductor sensor in which sensitivity is enhanced and stability of an amplifier is improved by forming a structure in which a capacitor and a sensor section are laminated on a driving circuit. CONSTITUTION:Since a driving circuit 10, a capacitor 30 and a sensor section 20 are so disposed in this order as to be longitudinally superposed on a single crystalline silicon substrate 1, an area of a photodiode to be formed of a lower electrode 31, a dielectric layer 32 and an upper electrode 33 can be reduced. Since a light is incident from the substrate 1 side to the sensor section 20, the light is incident to the section 20 without intermediary of the substrate, the sensitivity of a detecting wavelength range at a short wavelength side is not reduced by the substrate material, but the detecting wavelength range is increased. Further, the circuit 10 integrated on the substrate 1 is shielded by the electrodes 31, 33 and lead wiring 25 of the capacitor 30 thereby to highly integrate a semiconductor sensor and enhance sensitivity, thereby obtaining its stability.

Abstract: PURPOSE: To precisely segment the circumscribed rectangle of each character by providing a circumscribed rectangle extraction processing part which segments rows extracted from a document picture into circumscribed rectangles of black picture element groups. CONSTITUTION: A circumscribed rectangle extraction processing part 2 detects coordinates, where black picture elements are not included, in scanning lines perpendicular to a row and divides the row in these coordinates. A circumscribed rectangle discrimination processing part 2 discriminates whether two or more characters are included in a divided rectangle or not. A black run search processing part 4 searches a black run longer than a prescribed length in the row direction in the extracted circumscribed rectangle. A gap search processing part 5 searches a gap between the searched black run and the other black picture elements. If this black run is not an underline but is a part of a character as the result, this black run is left as it is. A line graphic erase processing part 6 erases the black run discriminated as an underline.  Thereafter, a circumscribed rectangle re-extraction processing part 7 detects coordinates, where black picture elements are not included, in scanning lines perpendicular to the row with respect to the circumscribed rectangle after removal of the underline and divides the row in these coordinates.
