    Abstract: An in-vehicle display device includes an image acquiring unit, a position predicting unit, and an image converting unit. The image acquiring unit acquires an image obtained by capturing an object existing around a host vehicle by a camera mounted on the host vehicle. The position predicting unit calculates a first positional relationship between the object and the host vehicle at timing T1 and calculates a second positional relationship between the host vehicle and the object at timing T2 after timing T1 based on the image acquired by the image acquiring unit and a capture timing. Furthermore, the position predicting unit predicts a third positional relationship between the host vehicle and the object at timing T3 after timing T2 based on the first positional relationship and the second positional relationship. The image converting unit converts the image acquired by the image acquiring unit such that the positional relationship between the host vehicle and the object becomes the third positional relationship predicted by the position predicting unit.

    Abstract: There is provided a calibration apparatus for calculating a camera installation parameter with respect to a flat surface without preparing two sets of parallel lines on the flat surface, with respect to which the camera installation parameter is to be obtained. An acquirer acquires a photographed image of two linearly-extending lines substantially perpendicular to a flat surface. An extractor extracts the two linearly-extending lines from the acquired image through image processing. A calculator calculates a vanishing point from the extracted two linearly-extending lines and calculates a camera installation parameter with respect to the flat surface on the basis of coordinates of the vanishing point and given coordinates different from the coordinates of the vanishing point.
