摘要： An illumination optical system includes a prism disposed on an incident optical axis and a lens that is disposed between the light source and an incident surface of the prism or between an emitting surface of the prism and an illuminated object, at least one of the reflection surfaces being a transmission/reflection surface. Additionally, an illumination optical system includes a prism having a surface that is disposed so as to obliquely intersect with an incident optical system, that transmits a part of the entering light to be emitted therefrom, and that deflects at least part of the rest of the light in a direction that intersects with the incident optical axis to be emitted therefrom. Furthermore, an illumination optical system has a rod lens that is disposed so that a longitudinal direction thereof is inclined with respect to an incident optical axis is provided.

摘要： The invention relates to an imaging apparatus that makes effective use of an image restoration processing method, thereby working favorably for size reductions while making sure zoom ratios and brightness, and ensuring good images. The imaging apparatus includes a zoom lens 1 comprising a plurality of lens groups G1 to G4 and adapted to implement zooming from a wide-angle end to a telephoto end with a change in a space between the plurality of lens groups, an imaging device 2 adapted to take an image formed through the zoom lens 1, and an image restoration processor 11 adapted to implement signal processing by which image restoration is implemented on the basis of a signal for the image taken by the imaging device 2 to generate an image signal for a restored image. The signal processing for implementing image restoration at the image restoration processor 15 involves processing for electrically implementing image restoration using a restoration filter on the basis of a point spread function regarding the imaging capability of the zoom lens 1. The zoom lens and the imaging device have a relation that satisfies condition (1) for balancing the power of restoration at the image restoration processor 11 against the total length of the zoom lens 1.

摘要： The invention relates to an image apparatus for endoscopes, which makes sure easier viewing especially at a peripheral portion of a screen while taking care of the observing angle of view and size of an optical system. The image apparatus comprises an optical system adapted to form an optical image of an object, an image pickup device adapted to convert the formed optical image into electric signals to obtain image data, and an image processing means adapted to move and transform a position of the optical image acquired by the image pickup device. A radiation direction magnification is transformable by the image processing means independently from a concentric direction magnification, and a magnification for a conformal object is higher at a peripheral portion than at a central portion of a screen.
