Title: Color reproducing method
Inventor: KANEDA TOSHIHIRO
IPC: H04N1/60
Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To suppress color appearance difference due to the lightness change of a high contrast part in performing color reproduction area conversion by compressing lightness difference with an achromatic color high contrast point in a narrow color reproduction area as reference and compressing or expanding saturation in each lightness value in a compressed color reproduction area. SOLUTION: A color signal converting means 12 converts an RGB signal that is inputted externally into CIELAB color space that is equal color space. Next, a color reproducing means 13 compares lightness in an achromatic color axis with a color reproduction area due to a signal of an image that is converted by a conversion table 17 and a color reproduction area 20 which is acquired from a printer profile 18 of a reproduced system and gets difference LL of a lightness area. The means 13 compresses through a higher order function by using the lightness difference LL with a high contrast point of the color reproduction area of the reproduced system as reference. Next, saturation in each lightness value is compressed or expanded in a compressed color reproduction area.

Abstract: PURPOSE:To prevent a lowering of sensitivity because of the decrease of effective areas, by forming a contact hole where a surface P<+> type layer is connected to a light-tight layer and providing the light-tight layer with the same electric potential as that of the P-type layer. CONSTITUTION:A contact hole 30 reaching the end part of a surface P<+> type layer 27 is made in an intermediate insulating layer 29. The size of the contact hole 30 is set to a size in such a way that the effective area of a photoelectric conversion part is not inhibited. An aluminum layer forming a light-tight layer 31 is used for shading at a charge transfer part as the light-tight layer 31 and is not used for wiring. As soon as the light-tight layer 31 is formed, aluminum in the light-tight layer 31 is filled even in the contact hole 30 to form a connection part to the surface P<+> type layer 27. In this way, when an electrode is taken out from the light-tight layer 31 which is connected to the surface P<+> type layer 27 by the connection part 32, a solid-state image sensor where the surface P<+> type layer 27 and a P-type well 22 have the same electric potential is obtained by providing the light-tight layer with the same electric potential as that of the P-type well 22.
