Abstract: In computation of a line-of-sight direction in a control unit, a first computed line-of-sight direction is obtained from the center of a pupil and a reflection point of cornea reflection light, a second computed line-of-sight direction is obtained by computing the ellipse shape of an iris or the pupil, and a third computed line-of-sight direction is obtained on the basis of a face orientation and the relative position of the iris or pupil in an eye. The line-of-sight direction can be computed over a wide range with high accuracy by selecting one of the computed line-of-sight directions.

Abstract: An illumination imaging device includes a combination of a polarizing plate, which is a grid polarizer, and a wave plate is provided at the intersection of an optical axis of a first light source that emits light and an optical axis of an imaging member. The light emitted from the first light source is reflected by the polarizing plate, is transmitted through the wave plate, and is fed to an object. The optical axis of the first light source and the optical axis of the imaging member coincide with each other. Therefore, a clear bright-pupil image is acquired by the imaging member.

Abstract: An input apparatus includes a central operation unit and a controller that controls an input operation to the central operation unit. The controller includes a determination unit that determines whether the central operation unit is going to be operated from, at least, a left side of the central operation unit or a right side thereof and a reference change unit that changes an operation reference direction of the operation unit in plan view in accordance with a determination result of the determination unit.

Abstract: Disclosed is an imaging apparatus capable of enlarging a portion of an image captured by an imaging device of a fisheye camera and displaying the enlarged image on a display screen with little distortion. The imaging apparatus enlarges a section, which is a portion of an image captured by a fisheye camera, and displays the section on a display screen such that the enlargement ratios of points in the section are different from each other. An image processing method uses a change function that changes the enlargement ratio of a field angle depending on the place is used, and converts a portion of the captured image into a central projection image to generate a display image. The use of the change function makes it possible to generate a display image having high visibility.

Abstract: A small-diameter positioning tube is formed in an external wall surface of a housing (upper case and lower case) that is a constructional element of a camera body via a stepped part. When the camera body is attached to a mounting base using screws, a positioning tube is fitted into an opening, and the stepped part is caused to abut on an outer peripheral edge of an upper surface of the opening. In this state, the screws are fastened so that the fastening force of the screws can be received by an abutting part between the stepped part and the opening. If the invention is constructed in this way, the fastening force of the screws does not directly act on the lens holding member that is received and fixed inside the housing, even if the camera body is firmly attached to the mounting base by the fastening force of the screws, any distortion caused in the lens holding member or a lens can be relieved.
