Light incident from one of the refraction surfaces is alternately reflected by the internal reflection surfaces of the first reflection surface group and the internal reflection surface of the second reflection surface group and guided to the other refraction surface. The width of at least one of the plurality of internal reflection surfaces of the first reflection surface group and at least one internal reflection surface of the second reflection surface group in a direction in which the two side surfaces oppose each other is smaller than the distance between the two side surfaces in the direction in which the side surfaces oppose each other.

摘要： A shifting amount of color compensation amount is calculated based on a shifting amount of color obtained from a shifting amount of color storage unit for each image forming unit, and shifting amount of color compensation in the pixel unit is performed by executing address conversion using the calculation result. A feature of an image to be processed is detected, and color density conversion compensation for performing shifting amount of color compensation in less than the pixel unit is performed according to the detected feature.

In the zoom optical system, an image of an object is formed through the plurality of optical elements, and zooming is effected by varying relative positions of at least two optical elements of the plurality of optical elements.

摘要： A disclosed optical apparatus comprises an optical unit including a light entrance surface, light reflecting surfaces and a light exit surface all of which are integrally formed of transparent material, and the optical unit has in its interior an internal refracting surface for refracting light. Since a light beam passes through the optical unit from the light entrance surface to the light exit surface via the internal refracting surface and the light reflecting surfaces along a bent optical path, the optical apparatus is reduced in size and improved in optical performance, particularly, well corrected in chromatic aberration. Another disclosed optical apparatus is arranged to achieve zooming by using a plurality of optical units each of which is similar to the aforesaid optical unit.

摘要： A reflecting-type optical system according to the invention includes an optical element composed of a transparent body having an entrance surface, an exit surface and at least three curved reflecting surfaces of internal reflection. A light beam coming from an object and entering at the entrance surface is reflected from at least one of the reflecting surfaces to form a primary image within the optical element and is, then, made to exit from the exit surface through the remaining reflecting surfaces to form an object image on a predetermined plane. In the optical system, 70% or more of the length of a reference axis in the optical element lies in one plane.
