Title: Image processor
Inventor: KAKEBE ISAO
IPC: G09G5/06
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in picture quality even in the case of displaying with various application programs by mapping from the color data of (a) bits to a color set in a color palette and gradation-reducing to the color data of (m) bits equal to or smaller than (a) bits. SOLUTION: In the case of an index color mode, a display of an image reads out successively the index pixel data stored in a frame buffer 141, and converts the index pixel data to the RGB data by the color palette 132 to send them to a DAC 133. A CPU 11 converts the image data to the color data of (a) bits, and selects a pixel conversion filter 112 long in processing time in the case of displaying a still image, and selects the pixel conversion filter 112 short in processing time in the case of displaying an animation. Then, the CPU 11 maps from the color data of (a) bits to the color set in the color palette 132, and gradation-reduces to the color data of (m) bits equal to or smaller than (a) bits.

Abstract: PURPOSE:To eliminate the closed structure of a device and to reduce its size and weight by employing a multi-layered structure for a resistance body. CONSTITUTION:This sensor M is constituted by putting a sensor main body in the storage case consisting of a bottom plate 2 and a cover 3 covering the bottom plate 2. Then the resistance body 8 and a current collector 8 are formed on the substrate 4 of the main body which is fixed to the bottom plate 2 and a slider 10 is so fitted as to slide in contact with them. This resistance body has the two-layered structure of a basic resistance body layer 21 formed opposite the substrate 4 in contact and a protective resistance body layer 22 formed thereupon. The volume characteristic resistance of the resistance body layer 22 is set higher than that of the resistance body layer 21. The resistance body layer 21 is therefore covered with the low resistance body layer 22 and shielded and protected from external temperature, humidity, and dust, and the slider 10 slides in contact with only the resistance body layer 22, so the resistance body layer 21 never wears. Further, the volume characteristic resistance of the resistance body layer 22 is high, so its wear hardly affects the resistance value of the whole resistance body 8.
