Abstract: Both converted image data obtained upon conversion of rearward image data taken by a camera by an imaging converting unit, and auxiliary display line data generated by an OSD creating unit are outputted as display image data on a display device. As a result, converted rearward images and auxiliary display lines are displayed superimposed on the display element. An operator displays the rearward images during conversion while utilizing the auxiliary display lines on the display screen to perform rotation processing, parallel movement processing, and skew processing until the image appears in a desired position.

Abstract: A vehicular display device adjustment method including an imaging step of taking an image of the periphery of a vehicle by imaging element, an image storing step of temporarily storing in an image storing element peripheral image data based on the peripheral image of the vehicle taken by the imaging element, a setting step of setting an adjustment mode for adjusting the display state of display element, a display control step of giving priority to the peripheral image based on the peripheral image data stored in the memory over the peripheral image taken in the imaging step in accordance with the adjustment mode set and displaying on the display element the peripheral image based on the peripheral image data stored in the memory, and an adjustment step of adjusting the display state of the display element based on the peripheral image.

Abstract: A red light sensor (222D), a green light sensor (232D), and a blue light sensor (242D) are provided on the LCD panel (200) of a display device (100). A processing section (170) of the display device (100) corrects, in an LCD correction control unit (173), a video image display state at positions corresponding to the red light sensor (222D), the green light sensor (232D), and the blue light sensor (242D) in the LCD panel (200) based on a state of outside light detected by the red light sensor (222D), the green light sensor (232D), and the blue light sensor (242D).

Abstract: In a convergence adjusting apparatus, there are generated waveform signals for adjustment, each level of which becomes zero at a plurality of adjustment points on a display except for one adjustment point. The levels of the waveform signals for adjustment are adjusted in accordance with convergence adjusting signals, and a convergence deflection yoke is supplied with the waveform signals having adjusted levels. In the convergence adjusting apparatus, only a beam spot at any adjustment point subjected to adjustment is moved when convergence adjustment is effected, without affecting adjustment for other adjustment points.
