Abstract

In an in-vehicle display apparatus and an in-vehicle proxy server operating in cooperation with the in-vehicle display apparatus, the in-vehicle proxy server modifies a content acquired from a server in accordance with vehicle running state information provided from an information providing unit such that a description specifying a linked content including display information not wanted or not necessary to be displayed on a display unit in the current vehicle running state is deleted from the content, and the in-vehicle proxy server supplies the resultant modified content to the browser. In accordance with the modified content supplied from the in-vehicle proxy server, the browser does not request the linked content including display information not wanted or not necessary to be displayed on the display unit.

the browser is operable to display the display information with the changed second display color on a display unit in accordance with the modified content.

8. The in-vehicle display apparatus according to claim 7, wherein the first display color corresponding to the lightness inside and/or outside of the vehicle becomes darker as the lightness inside and/or outside of the vehicle becomes darker.

9. The in-vehicle display apparatus according to claim 7, wherein the information indicating the lightness inside and/or outside of the vehicle is information generated based upon a parking light signal.

10. An in-vehicle display apparatus configured such that a browser requests that a server provide a content that includes display information and displays the display information included in the content provided from the server in response to the content request, the in-vehicle display apparatus comprising:

an in-vehicle proxy server operable to acquire the content provided from the server in response to the content request issued by the browser; and

an information providing unit operable to provide information to the in-vehicle proxy server indicating the screen size of a display unit,

wherein the in-vehicle proxy server is operable to (1) modify the content acquired from the server such that a layout of the display information is changed to a changed layout adapted to the screen size of the display unit in accordance with the information indicating the screen size, and (2) supply the resultant modified content to the browser; and

the browser is operable to display the display information in the changed layout on the display unit in accordance with the modified content.

11. An in-vehicle display apparatus configured such that a browser requests that a server provide a content that includes display information and displays the display information included in the content provided from the server in response to the content request, the in-vehicle display apparatus comprising:
