An optical device where an image of an object is formed on an image pickup element and where an image restoration process is performed on the image obtained by the image pickup element, comprising

Optical device and image pickup device and image pickup system using the same

An image pickup apparatus includes a plurality of optical systems, each having a different focal length, an image pickup element which picks up an image of an object by the optical system, and a zoom control section which changes an angle of field of an output image by at least one optical system from among the plurality of optical systems, and a part of the angle of field which changes is same as an angle of field of another optical system, and the image pickup apparatus further includes a control section which changes a control position of a display image at the time of zooming to be directed toward an optical-axial center of the another optical system for which the part of the angle of field is same.

Image pickup apparatus

A front-rear blur amount of a camera, which occurs when a release button is pressed in order to perform image pickup, is detected, and image data obtained by an imaging device on which an image of an object is formed are subjected to image processing on the basis of the front-rear blur amount. As a result, an image on which the effects of front-rear blur are reduced is obtained.

Image capturing system and image capturing method

When a photographer presses a release button by a predetermined amount after focusing on a first object, a focus lens is moved in an optical axis direction so that a second object is brought into focus, whereupon image pickup is performed while focusing on the second object. Image processing is then performed on image data obtained in the image pickup.

Image capturing system and image capturing method, involving image restoration processing

The invention provides an imaging apparatus and an imaging system, each one comprising an optical system having characteristics matching with image restoration processing, thereby achieving effective image restoration processing. To this end, the imaging apparatus or system comprises an imaging device, an optical systemfor forming a subject image on the imaging device, and an image processing meansfor implementing image processing for an image being viewed, the image produced out of the image device. The imaging apparatus or system is characterized in that the optical systemhas a substantially constant MTF at a position where the imaging deviceis located and in the predetermined distances before and after that position.
