There is provided an endoscope apparatus which enables to observe a three-dimensional image which is easy to view even in close observation.

An endoscope apparatus, comprises: optical systems which form images for a left-eye and a right-eye respectively; an image pickup element which captures the two images and generates pictorial images for the left eye and the right eye; and at least one image processing unit which carries out processing of a pictorial image signal from the image pickup element and creates a stereoscopic image that can be displayed on a monitor, wherein the endoscope apparatus satisfies the following conditional expression (1)

0.3<CP×(1+Dt1)<7, and CP≦10   (1) where, CP denotes a distance (mm) from a surface nearest to object of the optical system up to an object, when an amount of left and right shift of the left-eye pictorial image and the right-eye pictorial image becomes 0, at a center of a monitor screen, and Dt1 denotes a distortion in length at the maximum image height.

An image pickup optical system of an endoscope includes: a first optical member group that includes an objective optical member disposed closest to a subject side and an image-side optical member that is disposed adjacent to an image side of the objective optical member; a first lens barrel that holds the first optical member group; a second optical member group that is disposed on an image side of the first optical member group; and a second lens barrel that holds the second optical member group, as defined herein.

An illuminator apparatus and method for illuminating an object field imaged by a rectangular image sensor having a first aspect ratio is disclosed. The apparatus includes an optical fiber having a proximal end disposed to receive a plurality of input light beams, each light beam having differing spectral properties, the optical fiber being operable to transmit the light beams along the fiber to a distal end of the optical fiber. The apparatus also includes an integrating element disposed to receive the light beams from the distal end of the fiber and combine the light beams to produce a generally homogenous illumination beam at a rectangular output face of the integrating element. The apparatus further includes an illumination projector operable to project an image of the output face of the integrating element into the object field to produce a generally rectangular illuminated region of the object field substantially corresponding to the portion of the object field imaged by the rectangular image sensor.

An image capture apparatus according to an embodiment of the present technology includes an image generation unit, an edge detection unit, and a color control unit. The image generation unit generates a captured image by capturing a subject. The edge detection unit detects an edge portion included in the generated captured image. The color control unit controls a color of a highlighted display for highlighting the edge portion for each detected edge portion based on color information about the edge portion in the captured image.

A medical observation system 1 is provided with an imaging unit 21 which captures an image of a subject to generate a captured image, a distance information acquiring unit which acquires subject distance information regarding subject distances from a specific position to corresponding positions on the subject that correspond to at least two pixel positions in the captured image, and an operation control section 264c which controls at least any of the focal position of the imaging unit 21, the brightness of the captured image, and the depth of field of the imaging unit 21 on the basis of the subject distance information.

A surgical camera system, and method therefor, is provided which includes a plurality of imaging devices each having a tunable iris configured to change between at least two different sized numerical apertures.
