Abstract: PURPOSE:To permit the improvement of color reproducibility conforming a chrominance signal to the conditions that it is seen with human eyes by a method wherein a visual pigment film which generates photocurrent according to the intensity of a light is formed being pinched between a contact electrode and a transparent electrode. CONSTITUTION:A picture element part region 2 for sensing an optical image is formed at the central part of a substrate 1 and a driving part 3 of the picture element part 2 is provided on the periphery of this region. Then, a diffusion part 16 for charge storage and a contact electrode 12 to connect to a visual pigment film 11, which functions as a photosensor according to each picture element, are formed. Moreover, after the visual pigment film 11, which is one formed a visual pigment-containing cell membrane into a filmy form and functions as a photosensor, is laminated on the whole surface of the picture element part 2, a transparent electrode 10 is formed on the whole surface on the region 2 and a color filter 7 is installed on the front of the picture element part 2. Thereby, the color reproducibility can be improved being well-balanced a chrominance signal obtainable through the filter 7 to the conditions that it is seen with human eyes.

Abstract: PURPOSE:To make a wavelength characteristic of an optical sensor approximate to the visibility of a human being by using a visual matter for a photosensitive part. CONSTITUTION:A thin film 3 of a cell membrane containing bacteriorhodopsin which has been isolated from a halophile is electro-deposited onto a transparent electrode 2 which has been vacuum-evaporated on a glass substrate 1, and also the second electrode 4 is vacuum-evaporated on said film, by which a photosensitive part is formed. A source 6 and a gate 7 of a field effect transistor 5 are connected through a conductive circuit 11 to the transparent electrode 2 and the second electrode 4 of the photosensitive part, respectively, and a drain 8 is connected to the conductive circuit 12 to the source 6 through a DC power source 9 and a resistance 10, by which a detecting/amplifying part of a photoelectromotive force which has been generated in the photosensitive part is formed. A variation of a drain current caused by a light irradiation of the photosensitive part is recorded in a recorder 12, as a variation of an across voltage of the resistance 10.

Abstract: PURPOSE:To efficiently form a highly homogenous membrane layer, by treating the surface of a substrate with a coupling agent and forming a purple membrane-containing membrane layer due to the polymerization of acrylamide to the treated surface. CONSTITUTION:A purple membrane is the one isolated from Halobacterium halobium being one kind of halophil and contains bacteriorhodopsin being chromoprotein and is dissolved in an aqueous solution containing 5-15wt% of acrylamide to obtain a desired acrylamide solution. A substrate such as a glass substrate, an ITO electrode substrate or a metal plate is treated with a silane coupling agent and acrylamide is polymerized while the acrylamide solution containing the purple membrane is contacted with the surface of the surface treated substrate to form a homogenous membrane layer of a purple membrane-containing acrylamide gel.
