Patent number: 6518803Abstract: The present invention discloses an output circuit, by which it is possible to reduce power consumption while maintaining maximum voltage value to be outputted at high level. In this output circuit, a charge-and-discharge circuit uses a terminal voltage Vc of a capacitor as a trapezoidal wave voltage, and a drive circuit drives an output transistor based on the terminal voltage Vc, and a voltage Vo equal to the terminal voltage Vc is outputted to the load. A voltage detection circuit detects an emitter voltage (Vc+VF) of the transistor and generates an electric current proportional to the terminal voltage Vc. This electric current is turned to a base current of the output transistor via a variable current circuit. Therefore, a base current proportional to the output voltage Vo is supplied to the output transistor.Type: GrantFiled: November 8, 2001Date of Patent: February 11, 2003Assignee: Denso CorporationInventors: Junichi Nagata, Akio Kojima

Publication number: 20020021834Abstract: The invention relates to the image processing, and more particularly to the image processing method, the image processing apparatus, and the image processing system that compress color data. In order to extract the representative color from a small region on the color image in order to approximate to the color image, the invention performs the calculating of an average and a variance of color data of the small region, the color of which the variance is the largest is determined as a target color. According to the average of the target color, the small region is divided into two sections. After calculating the region information of the two sections and each representative color of section, judging whether the obtained number of representative colors is more than the requested number of colors, if the obtained number is more than the required number of colors, the dividing is completed.
