INFORMATION DISPLAY APPARATUS AND INFORMATION DISPLAY METHOD
First Claim
1. An information display apparatus that is provided in a vehicle including a first camera which captures a foreground image, the information display apparatus comprising:
- an optical flow calculating unit that is configured to acquire a plurality of foreground images captured by the first camera and to calculate vector information of an optical flow of a foreground on the basis of the acquired plurality of foreground images;
a motion effect determining unit that is configured to acquire the vector information of the optical flow from the optical flow calculating unit and to determine a motion effect of a predetermined image on the basis of the acquired vector information of the optical flow; and
a display unit that is configured to display the predetermined image while being moved in accordance with the motion effect determined by the motion effect determining unit.

Abstract
An aspect of the invention provides an information display apparatus and an information display method which allow a driver to easily recognize the display information without discomfort, regardless of the traveling state of a vehicle. It includes an attention object detecting unit (32) which detects information to be displayed to the driver, a symbol image selecting unit (33) which sets a symbol image to be displayed for the driver, an optical flow calculating unit (34a) which detects an optical flow of a foreground of the own vehicle, a motion effect determining unit (35) which sets a motion effect to be added to the symbol image, a display image generating unit (36) which generates a display image in which the motion effect added by the motion effect determining unit is combined with the symbol image, and a display control unit (37) which displays the generated display image for the driver. The motion effect determining unit (35) changes the motion effect to be added to the symbol image in accordance with the traveling state of the vehicle.
