Abstract: This backlight device (illumination device) is provided with (LEDs) light source; a light guide plate having a light-receiving face that opposes the LEDs and where light from the LEDs is incident, and a light-exiting surface where the incident light is emitted; and an optical sheet (optical member) arranged in opposition to the light-exiting surface of the light guide plate and imparting an optical effect to the light emitted from the light-exiting surface. Here, the optical sheet has, in at least one portion thereof, a chromaticity correction region for which x and y chromaticity coordinate values in a CIE 1931 color space both decrease with distance from the LEDs.

Abstract: An input device, wherein the screen (18a) of a display device (18) is divided into two regions, a region (A1) and a region (A2), and the icon switch displayed in the region including the position of an invisible pointer (P?) is selected. Thus, one of an icon switch (1) and an icon switch (2) that are displayed on the screen (18a) is selected at any time. Consequently, the user will no longer have to watch the screen carefully and perform an operation for moving an instruction marker such as a visible pointer to a desired icon switch, for example as in conventional devices. Accordingly, the user can enter a desired instruction in a short time by selecting a desired icon switch in a short time.

The optical sheet member includes a protrusion protruding toward the light source and fixed to the light guide plate.

Abstract: An on-board camera calibration device with high productivity is provided which allows speedy calibration of the on-board camera with high precision with a simple construction. Based on an actual coordinate specified in a projecting plane of a camera coordinate system and a converted coordinate obtained by converting an initial coordinate of a calibration point with using unfixed camera adjustment values, the adjustment values corresponding to angles of rotation about one or two axes from among three axes of the camera coordinate system are calculated and the camera adjustment values are updated. Based on the actual coordinate and the converted coordinate in accordance with the updated camera adjustment values, the adjustment values corresponding to angles of rotation about the remaining axes of the camera coordinate system is calculated and the camera adjustment values are updated. When the predetermined completion condition is satisfied, the updated camera adjustment values are fixed.

Abstract: Provided is a calibrating apparatus for an on-board camera of a vehicle, which apparatus allows completion of calibration process with a simple additional calibration, even when rejection has issued on the result of automatic calibration. Based upon a camera parameter obtained at the time of completion of adjustment by an automatic adjusting section, a confirmation marker indicating the position of coordinate of a calibration point is displayed in superposition with a camera-captured image. A manual adjusting section adjusts the camera parameter, based on an amount of displacement of the coordinate of the calibration point corresponding to an amount of movement of the confirmation marker moved in response to input of adjustment instruction.
