摘要： The invention provides a projection screen, wherein clear images can be obtained without being influenced by projection environments, the flexibility can be obtained, and its manufacturing cost can be reduced and its manufacturing method. An optical multilayer film is formed on a transparent substrate by alternately layering metal films and dielectric films by using spattering. This multilayer film has the high reflection characteristics in relation to three primary colors wavelength bands lights, and has the high absorption characteristics in relation to lights other than the three primary colors wavelength bands lights. Therefore, the white level and the black level of images can be raised. Further, in terms of the optical multilayer film, as the film thickness dependence of the reflectance change becomes smaller and the incidence angle dependence of reflectance change becomes smaller, a wide visual field angle can be obtained.

摘要： An image pickup element includes a light receiver having a matrix arrangement formed by disposing first-direction arrays, each having photoelectric converters arranged in a first direction with a gap therebetween, in a second direction orthogonal thereto, and micro-lenses above the light receiver. In the matrix arrangement, a certain first-direction array has two first photoelectric converters receiving, via two micro-lenses, photographic-subject light passing through two segmental regions in an exit pupil of a photographic optical system, and a certain second-direction array has two second photoelectric converters receiving photographic-subject light passing through two segmental regions in the exit pupil. Light axes of the two micro-lenses extend through vicinities of edges, farthest from each other in the first direction, of the first photoelectric converters. The first photoelectric converters include two photoelectric converters that flank one photoelectric converter, disposed at an intersection between the certain first-direction and second-direction arrays, in the certain first-direction array.
