IPC: H01L31/10
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To provide a light-receiving device for obtaining stable output level from a light-receiving element. SOLUTION: Output signals S1a to S4d from each region of a light-receiving elements 1 divided into 16 portions are sequentially selected in a first selection circuit 2, and the output level selected for each selection is stored in a storage circuit selected at each selection. If it is higher than the reference level Vref1, then the region of the light-receiving element is stored in a memory circuit 7. When the selection of the means of the first selection circuit 2 is completed, the output from a memory circuit 7 selects a region higher than the reference level Vref1, and based on this, an output signal higher than the reference level 1 is set in a second selection circuit 5. An output signal from the second selection circuit 5 is added in an adder circuit 8 and then transmitted to a post-stage circuit.  When the selection for the means of first selection circuit 2 is finished, a control circuit 6 selects from among the outputs stored in a storage circuit 7 the highest level and the second highest level. Based on this, a second selection circuit is made to select the highest and the second highest level output signals by the second selection circuit 5. The output signal of the second selection circuit 5 is added by an addition circuit 8 and then transmitted to a post-stage circuit.

Abstract: PROBLEM TO BE SOLVED: To easily and accurately draw a tilted ellipse which simultaneously touches two optional straight lines on a display screen by means of a computer. SOLUTION: The following processes are executed by a computer. That is, two points are designated on each of two straight lines on a display screen (S1). The point of contact between a tilted ellipse and one of both straight lines is designated, together with a point of contact between the tilted ellipse and the other straight line (S2, S3). A single point is designated on the tilted ellipse, excluding two points of contact (S4). The equation for a secondary curve is obtained, based on the position coordinates of two points set on each of two straight lines, the position coordinates of two points of contact and the position coordinates of the single point (S5). When the equation represents an ellipse (S6), the position coordinates of every point set on the tilted ellipse is calculated by the equation (S7).  Then the tilted ellipse is drawn on the display screen, based on the position coordinates which are calculated by the equation (S8).

Title: Image processing unit
Inventor: MINAMINO KATSUMI
IPC: G06T3/40
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To provide an image processing unit that magnifies/reduces an image with a simple method without deteriorating the image quality. SOLUTION: When entering a percentage of magnification/reduction from a ten-key pad 16a of an operation section 16, an MPU 11 decides a multiple m/n based on the percentage. Furthermore, the MPU 11 decides a ratio of weighting through addition/subtraction of a numerator (m) and a denominator (n) of the magnification m/n. Then the MPU 11 calculates a pixel density after conversion based on a pixel density before conversion with respect to the pixel density after the conversion. Thus, magnification/reduction can be conducted with a simple method without deteriorating the image quality.
