Abstract: A variable magnification optical system includes: a first lens group (G1) having a positive refractive power and arranged closest to an object; a negative lens group (G2) having a negative refractive power and arranged closer to an image than the first lens group; a positive lens group (G4) which has a positive refractive power, which includes at least one lens that is arranged closer to the image than an aperture stop (S), and which is arranged closer to the image than the negative lens group; and a focusing group (G3) arranged between the negative lens group and the positive lens group, wherein when varying magnification, the first lens group moves with respect to an image plane, a distance between the first lens group and the negative lens group is changed, and a distance between the negative lens group and the positive lens group is changed, wherein when focusing, a distance between the focusing group and a lens arranged at a position to face an object-side of the focusing group is changed, and a distance between the focusing group and a lens arranged at a position to face an image-side of the focusing group is changed, and wherein a predetermined conditional expression is satisfied.

Abstract: A catadioptric system (LS) is provided with: a first reflecting mirror (M1) that reflects light from an object; a second reflecting mirror (M2) that reflects light reflected by the first reflecting mirror (M1); a first lens group (G1) that transmits light reflected by the first reflecting mirror (41) and travelling toward the second reflecting mirror (M2), and transmits light reflected by the second reflecting mirror (M2); and a second lens group (G2) that transmits light reflected by the second reflecting mirror (M2) and transmitted through the first lens group (G1). The catadioptric system is configured that an image of the object is formed by light transmitted through the second lens group (G2).

Abstract: An image processing apparatus includes a plurality of image processing module parts, a module arbiter part, and a DMAC (Direct Memory Access Controller) part. Each of the image processing module parts includes a module core for executing a predetermined image processing. The plurality of image processing module parts is connected to the module arbiter part. The module arbiter part arbitrates memory access which is given by the plurality of image processing module parts through a bus. The DMAC part is connected between the module arbiter part and the bus, and executes memory access related to the arbitration result obtained by the module arbiter part.
