Abstract: In an on-vehicle display device, projection light output from a projecting unit is reflected on an intermediate mirror and is further reflected on a directional mirror. The reflected light is directed to a windshield glass as directed reflected light. In an adjustment operation, the directional mirror is rotated around tilting fulcrum parts by a driving unit to adjust the height of a virtual image formed in front of the windshield glass. In a retracting operation, the lower end of the directional mirror is largely moved forward by the driving unit, rotating the directional mirror with an abutting point between the directional mirror and the upper support acting as a fulcrum. This prevents external light (sunlight) from adversely affecting the projecting unit.
Abstract: When it is possible to capture a plurality of light sources as images of a plurality of separated light sources with a gain within a range for each of the ranges of mutually different gains, images captured with the maximum gains among the gains that enables the capturing as the images of the plurality of light sources, that is, images captured to be the brightest is generated as use images (a, b, and c). Then, an image d, obtained by combining only the use images (a and b) in which the plurality of light sources is successfully captured as the images of the plurality of separated light sources among the generated use images, is displayed on a display.
Abstract: A navigation screen generator displays only icons of objects of an object category set as “DISPLAY” in an icon presentation control table on a map image. If a touch occurs at a position on the map image of the navigation screen where no icon is displayed, a controller sets the object category of the object corresponding to the touch position as “DISPLAY” in an icon presentation control table. Then, icons of the objects having the same object category as that of the object corresponding to touch position are displayed on the map image of the navigation screen.

Abstract: An operation apparatus detects a finger using a sensor disposed on an operation plane and further determines a movement distance of the finger so as to change an operation of a controlled device, such as an in-vehicle air conditioner. A finger touching or approaching the operation plane is detected by an electrostatic sensor. An air volume of the air conditioner which is the controlled device is changed by a movement of the detected finger in an X1 or X2 direction. When the finger is moved by a first distance from a first detected position, the air volume is changed in a predetermined range. Thereafter, every time the finger is moved by a second distance which is different than the first distance, the air volume is changed in a range equivalent to a range in the case of the movement by the first distance.

The front panel is bonded to the bracket of the display unit by a first adhesive layer and is bonded to the support piece by a second adhesive layer.
Abstract: Two subsystems, each including a microphone, a speaker, a canceling sound-generating adder, an error-computing adder, and two adaptive filters and two auxiliary filters that accept two noises as input, are provided in correspondence with two cancellation positions. Each canceling sound-generating adder adds together the outputs from the adaptive filters and outputs the result to the speaker of each subsystem. Each error-computing adder adds together the output from the microphone of the subsystem and the output from the auxiliary filter of the subsystem, and the result is treated as the error of the adaptive filters of each subsystem. A transfer function is learned in advance and set in each auxiliary filter such that each error computed by each error-computing adder becomes zero (0) when a transfer function in which each noise is canceled at each cancellation position in a predetermined standard acoustic environment is set in each adaptive filter.
