Title: Luminance unevenness correction circuit
Inventor: SHIBATA SHINICHI
IPC: H04N5/66
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To correct luminance unevenness without losing the gradation property of a picture by using the luminance unevenness correction of the picture by means of combining a timing generation circuit, a multiplication circuit and a bit compression circuit. SOLUTION: A timing signal designating the position of a vertical direction is generated from a horizontal synchronizing signal and a vertical synchronizing signal, which are inputted in a timing generation circuit 7. An output digital signal from a multiplication circuit 3 is inputted to a bit compression circuit 8 and a bit is compressed. Then, the signal is inputted to a liquid crystal module 9. A coefficient, generated in a coefficient generation circuit 4 is multiplied by digital video signal data from an AD converter 2 by a multiplication circuit 3. The prescribed coefficient is multiplied in the line of high luminance and 1.00 is multiplied in the position of low luminance. Thus, the output digital signal can be converted by switching the coefficient by the number of lines and conversion is executed in all lines.  Thus, luminance becomes constant in spite of the position of the vertical direction and luminance unevenness can be corrected.

Abstract: PURPOSE:To improve the optical characteristics by forming a dielectric thin film on a metallic thin film while their thickness are specified and specifying variances of visible light transmissivity and visible light reflectivity. CONSTITUTION:The metallic thin film 2 of 50-250Angstrom  in thickness and the dielectric thin film 3 of 400-2,000Angstrom  are laminated in this order on one surface of a transparent base body 1.
