Title: Device and method for processing image
Inventor: MATSUOKA HIROCHIKA
IPC: G06T7/00
Filed: 1999-09-08
Abstract: PROBLEM TO BE SOLVED: To provide a device and method for processing image by which the signal in a certain color space can be converted into the signal in another color space with high accuracy in a short time without preparing data for inverse conversion in advance. SOLUTION: When the input signal of a Lab color space is converted into the output of an RGA color space, a chrominance signal converting section 102 converts the given signal of the RGA color space into the signal of the Lab color space. A potential calculating section 103 extracts the difference between the input signal and the chrominance signal outputted from the converting section 102. An extremely small potential searching section 104 searches the signal which makes the extracted difference extremely small and is to be given to the converting section 102 and outputs the searched result as the converted chrominance signal of the RGB color space.

Inventor: ONDA SHOICHI
IPC: G02F1/1335
Filed: 1994-09-22
Abstract: PURPOSE: To provide a liquid crystal display device with a high light using efficiency by simply constructing an optical system with lens effect given to a liquid crystal panel itself to restrain surface reflection. CONSTITUTION: With a Fresnel lens provided on a surface substrate 10 for a reflection liquid crystal panel 100, an optical system is formed in a simple structure to prohibit surface reflection so that it can be refracted to the direction of requiring light from a light source to project an image. No extra optical system is required because incident light bending function is given to the liquid crystal panel substrate 100 itself. Since it is integrally formed on the liquid crystal panel substrate, surface reflection is restrained, no optical axis shift occurs and a whole display device is in a simple structure. Color display is performed by a color filter, a high-brightness display image is obtained with scattering liquid crystal and a clear image is provided. On this account, the liquid crystal display device has good performance in an inexpensive structure.  If constructed as a reflection OHP device, a compact optical system is achieved.

This corresponds to a normal operation mode. When the signal X is L and the signal/X is H, the transistors MP2, MP3 are respectively off, and this is a static current test mode. A multiplexer 64 also conducts approximately same switching operation at signals Y,/Y. Thereby, the multiplexer switches the normal operation time and the static current measuring time so that the quality of a device can be judged.
