Title: Solid-state image sensing element
Inventor: WATABE TOMOYUKI
IPC: H04N5/374
Filed: 1990-03-02
Abstract: PURPOSE:To realize a contour emphasis function of an image without hardly increasing an area by a method wherein the degree of continuity of a gate element which reads out an output signal of a photodiode is controlled by a difference signal between the output signal and an output signal of a photodiode of a neighboring picture element. CONSTITUTION:During a photodetection operation of an image sensing element, an electric charge flows out, to a certain extent, from an output terminal of a P whose electric charge is much to an output terminal of a P whose electric charge is little by an influence of resistances R's and r's. When an image is uniform near a picture element to which attention is being directed, an electric current does not flow to the resistances R's and r's, and a voltage across the resistances R's is zero. When the photodetection amount of a picture element to which attention is being directed (picture element in the upper left) is much and the photodetection amount of a neighboring picture element (picture element in the upper right) is little, an output of a left diode P is low and an output of a right diode P is high; an electric current flows via the resistances R's and r's and a voltage is generated across the resistances r's. As a result, a gate voltage VES becomes a positive finite value at the left picture element and a negative finite value at the right picture element. When an element characteristic of a gate PG is formed to be ON when the VES is positive and to be OFF when it is negative, an output becomes increasingly large at the left picture element and becomes small at the right picture element, and contours are emphasized.

Title: Color electronic copying device
Inventor: KASAHARA NOBUO
IPC: G03G15/01
Filed: 1986-03-07
Abstract: PURPOSE:To reduce the power consumption of a fixing heat source and to prevent an image from shifting in position and color by setting the distance from a separation claw to a fixing roller to larger than the maximum image size and making the conveyance speed of a sheet lower than the peripheral speed of the fixing roller. CONSTITUTION:The length extending from the separation claw 27 which abuts on a transfer drum 19 to the fixing roller 29 is set longer than the peripheral length of the photosensitive body with which the maximum image can be formed, and the moving speed of an endless belt 28 is set larger than the peripheral speed of the transfer drum 19. The moving speed of a sheet clamped between a roller couple 29 is held lower than the peripheral speed of the drum 19 to prevent end parts of sheets of the maximum size which are conveyed successively from overlapping with each other. Thus, the speeds are set to suppress variations in the speed of a sheet clamped between the roller couple and an image on a sheet is prevented from contacting a nearby member owing to the swelling of the sheet at the clamping position. Thus, a fixation time is shortened to reduce the power consumption, thereby preventing the image from shifting in position and color.
