Abstract: An in-vehicle display control device includes: an image acquisition unit that acquires a plurality of element images to be displayed on a vehicular display from each image generation unit; a change information acquisition unit that acquires color change information; and an image synthesizing unit that generates a synthetic image based on a color in the color change information and the plurality of element images. The image synthesizing unit generates the synthetic image by synthesizing the plurality of element images and a color change layer.

Abstract: A vehicle display device includes: a display; a vehicle information image generator; an external image obtaining device; a display controller that displays the vehicle information image and the external image on the display; and an external image display determination device that determines whether the display controller is going to display the not displayed external image. When the display controller is going to display the not displayed external image, the display controller displays the external image, which the display controller is going to display, on the display with gradually increasing brightness of the external image from the brightness that is lower by a predetermined amount than original brightness to predetermined brightness that is determined based on the original brightness.

Abstract: A vehicle display control device includes a timing determination unit that determines timing when it is authenticated that the mobile terminal is an object that can provide the mobile screen information after the start of processing of connection between an HCU and the mobile terminal. A display control unit displays a during-connection-processing image indicating that connection with the mobile terminal is being processed, on the display device after the timing is determined by the timing determination unit until the mobile screen information becomes possible to be displayed on the display device. The display control unit does not display the during-connection-processing image on the display device after the connection processing is started until the timing is determined by the timing determination unit.
