Information display apparatus and information display method

An information display apparatus that is provided in a vehicle including a sensor which detects speed information and rotational speed information, the information display apparatus comprising:

• an optical flow calculating unit that is configured to acquire the speed information and the rotational speed information from the sensor and to calculate vector information of an optical flow of a foreground on the basis of the acquired speed information and rotational speed information;
• 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.

An information display method that is implemented in a vehicle including a camera which captures a foreground image, the information display method comprising:

• allowing an optical flow calculating unit to acquire a plurality of foreground images captured by the camera and to calculate vector information of an optical flow of a foreground on the basis of the acquired plurality of foreground images;
• allowing a motion effect determining unit 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
• allowing a display unit to display the predetermined image while being moved in accordance with the motion effect determined by the motion effect determining unit.
