Abstract: The present invention provides a focus device, an imaging system, and a method of outputting a focus-lens drive signal each capable of securing the amount of infrared rays incident on a focus sensor. Visible rays and infrared rays included in the incidence rays are transmitted through a first region of a diaphragm and the infrared rays are transmitted through a second region of the diaphragm. The visible rays are transmitted through a dichroic mirror, and are incident on an image sensor. The infrared rays are reflected by a reflection surface of the dichroic mirror, and are incident on a focus sensor. A focus-lens drive signal is output from the focus sensor, and is input to a focus-lens drive unit. A focus lens is driven by the focus-lens drive unit. The amount of rays incident on the focus sensor is not decreased, and hence precise focusing can be performed.

Abstract: An image for a left eye and an image for a right eye are respectively captured. A corresponding point corresponding to each of a plurality of feature points detected from the image for a left eye is searched for using the image for a right eye. The number of corresponding points found by the search is counted, and it is determined whether to be equal to or more than a predetermined ratio with respect to the number of pixels of the image for a right eye. When the number of corresponding points is determined to be less than the predetermined ratio, the image for a right eye is recaptured, and the corresponding point search process and the determination of whether the number of corresponding points is equal to or more than the predetermined ratio are re-executed using an image new for a right eye obtained by recapture.

Abstract: Designated positions in a left-eye image and in a right-eye image are detected. The dominant eye is input and, if there is a position designation made by the observer, the coordinate position of the designated position is calculated in each of the left-eye and right-eye images. A template image is detected from the dominant-eye image and an image identical with the detected template image is detected from the non-dominant-eye image. Positions in respective ones of the template image and matching image become the designated positions. A distance differential between the template image detected from the dominant-eye image and the image detected from the non-dominant-eye image is parallax. The parallax of the designated positions is adjusted.
