Patent number: 7865076Abstract: A lens module (7) that includes a plurality of lenses (1a, 1b), a plurality of optical filters (2a, 2b) corresponding to the individual lenses (1a, 1b), an imaging device (4) that includes a plurality of imaging regions (4a, 4b) corresponding to the individual optical filters (2a, 2b), and a light-shielding wall (61a to 61d) that is provided perpendicularly to the imaging device (4) are provided. The adjacent imaging regions (4a, 4b) are partitioned by the light-shielding wall (61a). The light-shielding wall (61a) includes a plurality of inclined surfaces (63) that are inclined with respect to an imaging plane of the imaging regions (4a, 4b), and the plurality of inclined surfaces (63) are disposed sequentially from a side of the lens module (7) to a side of the imaging regions (4a, 4b). Each of the inclined surfaces (63) is inclined toward the side of the imaging regions (4a, 4b) with increasing distance from the light-shielding wall (61a).Type: GrantFiled: April 13, 2007Date of Patent: January 4, 2011Assignee: Panasonic CorporationInventors: Satoshi Tamaki, Tatsutoshi Suenaga, Katsumi Imada

Patent number: 6370337Abstract: A system for recording and reproducing a color image of a scene includes an image recording apparatus including a body portion for containing components of the apparatus and for housing a roll of black and white silver halide emulsion film. The body portion includes a focal lens for focusing scene illumination to expose the film with the scene image. A color filter disposed in the body portion filters the scene illumination. The filter includes a color filter array having a plurality of adjacent pixel arrays, whereby the scene illumination is pixelated on the black and white film for each array as units of luminance and chrominance information.Type: GrantFiled: April 7, 2000Date of Patent: April 9, 2002Assignee: Eastman Kodak CompanyInventor: Stanley W. Stephenson
