Abstract: When a browser is displayed on an in-vehicle information processing device, an appropriate display screen is displayed according to a driving state of a vehicle. While moving, web content is processed based on a restriction rule so that a moving image or the like is not reproduced. Further, when an operation of switching a display from another application other than the browser to the browser or an operation of switching a display to another web content on the browser is input to an in-vehicle terminal, the driving state of the vehicle is determined. In a state in which the vehicle stops, web content is displayed without change, and in a state in which the vehicle is moving, when processed web content is being stored, the processed web content is read and displayed, and when processed web content is not being stored, web content is read, processed based on the restriction rule, and then displayed.
