Display control apparatus for a vehicle information display
In a display control apparatus, a cooperation unit capable of detaching from a meter device is prepared, and a smartphone is connected to the cooperation unit. The display control apparatus responds to changes in specification of a smartphone by cooperation function of the cooperation unit. The cooperation unit reads a cooperation pattern number stored in a memory on a meter device, and grasp an output image size, a display position, presence and absence of blank image. The cooperation unit receives an image data on a screen of the smartphone, and transmits image data in which change of display size, position adjustment and so on is performed to the meter device. The cooperation unit accepts a user input operation on an operation input device, transmits it to the smartphone so as to enable remote operation during driving.
1. A display control apparatus comprising:
a first controller connected to a display unit and configured to output image data to the display unit and display an image on a display screen; and
a second controller retrofitted to the first controller and configured to output image data input from an external terminal to the first controller,
wherein the first controller includes a storage unit that stores layout information on a display form of an image on the display screen, and
wherein the second controller includes a data modification unit configured to acquire the layout information from the first controller, correct the image data input from the external terminal into data in accordance with the display form based on the layout information, and output the data to the first controller.
2. The display control apparatus according to claim 1 , wherein
the layout information contains information on a display size of an image on the display screen, and
the data modification unit corrects the image data input from the external terminal so that a display size of the image data matches a display size contained in the layout information.
3. The display control apparatus according to claim 1 , wherein
the layout information contains information on a display position of an image on the display screen,
the second controller corrects the image data input from the external terminal so that an image of the image data on the display screen is in a display position contained in the layout information.
4. The display control apparatus according to claim 1 , further comprising an operation input unit configured to output an operation signal for changing an output state of image data in the external terminal according to an input operation,
wherein the second controller outputs the operation signal input from the operation input unit to the external terminal and changes the output state.
5. The display control apparatus according to claim 1 , wherein
the display screen is a meter display that displays information indicating a traveling state of a vehicle, and
the first controller acquires the information indicating the traveling state, generates image data related to the traveling state, synthesizes an image of the generated image data and an image of the image data input from the external terminal, and displays the synthesized image on the display screen.
