An image processing apparatus generates a left-eye viewpoint image and a right-eye viewpoint image, detects one or more pairs that are each a pair of a partial image of the left-eye viewpoint image and a partial image of the right-eye viewpoint image that are similar to each other, performs, for each of the one or more pairs, image adjustment processing for adjusting the three-dimensionality of one of or both of the partial images of the left-eye and right-eye viewpoint images, displays the left-eye viewpoint image or the left-eye viewpoint image after the image adjustment processing in a manner such that this image is capable of being observed with a left eye, and displays the right-eye viewpoint image or the right-eye viewpoint image after the image adjustment processing in a manner such that this image is capable of being observed with a right eye.

Image processing apparatus, image processing method, and recording medium having image processing program recorded therein

An observation apparatus includes an imaging unit, a driving mechanism, an operation circuit and a control circuit. The imaging unit generates image data by imaging a target object. The driving mechanism moves the imaging unit to change an imaging position of the target object. The operation circuit calculates information on imaging conditions of the imaging unit based on an auxiliary information calculation image, which is image data of auxiliary information calculation light. The control circuit controls the imaging performed by the imaging unit, using the information on the imaging conditions.

A camera operates in cooperation with a wearable image display apparatus configured to be wearable on an eye region of a user. The camera includes an imaging unit, a vibration detection unit, a transmission availability judgment unit and a communication unit. The imaging unit acquires an image of a subject. The vibration detection unit detects vibration of the camera. The transmission availability judgment unit permits transmission of the image acquired by the imaging unit to the wearable image display apparatus when the vibration detection unit does not detect the vibration of the camera, and prohibits transmission of the image acquired by the imaging unit to the wearable image display apparatus when the vibration detection unit detects the vibration of the camera. The communication unit transmits the image acquired by the imaging unit to the wearable image display apparatus when transmission of the image acquired by the imaging unit is permitted.

The design method of the optical system according to the present invention comprises a step (S) for setting an optical parameter in a design state in which a production error has not been taken into consideration, a step (S) for making/renewing a production state where an optical parameter in a production state is made by adding the production error to the optical parameter in the design state, or the production error of the optical parameter in an existing production state is renewed, a step (S) for making an evaluation function which makes the evaluation function and a step (S) for performing optimization which determines an optimal optical parameter by optimizing the evaluation function.

Method of designing optical system

According to the present invention, light from a taking lens is reflected by a quick return mirror in a lateral direction of a body unit. Then, after passing through a screen, the light is reflected toward an upper side of the body unit by a second mirror except part of the light. The light reflected by the second mirror is reflected by a third mirror in a direction opposite to a direction in which the light is reflected by the quick return mirror, and is further reflected by a fourth mirror toward an eyepiece located on a back side of the body unit. Part of the light which passing though the screen is taken by an AF sensor unit provided in rear of the second mirror, and an image formation position of an optical image is detected.
