Abstract:
1. An image processing device in which a position of an index in a picked-up image picked up by an image pick-up device is detected by a template matching process employing a template image of the index, comprising: an orientation sensor that measures an orientation of said image pick-up device; a prediction position calculation unit that calculates a prediction position of the index in an image picked-up by said image pick-up device on the basis of the measured orientation; an extracting unit that sets an area of the picked-up image on the basis of the prediction position of the index, and extracts an image in the set area; a rotating unit that rotates the extracted image using a rotation angle in a roll angle, according to the measured orientation, of said image pick-up device, and outputs the rotated image as a target image; and a detecting unit that detects the position of the index in the picked-up image by performing the template matching process between the template image and the target image.
