摘要： A coordinate determining system is disclosed. The coordinate determining system comprises an image capturing module, a dividing module, a determining module, and a converting module. The image capturing module is used for capturing a plurality of images corresponding to the screen. The dividing module is used for dividing an overlapping image region of the images into a target image comprising a plurality of sub-regions. The determining module is used for determining a position of the indicating point on the target image. If the indicating point is in a target sub-region among the sub-regions and has an image coordinate relative to an original of the target sub-region, the converting module will convert the image coordinate into the screen coordinate according to a proportional parameter.

摘要： The invention discloses a method for displaying a stereoscopic image, wherein the stereoscopic image includes a first-eye image and a second-eye image. The method is to firstly calculate a shift of the first-eye image with respect to the second-eye image. Then, the method moves the first-eye image for a length of a shift. Afterward, the method outputs the moved first-eye image and the second-eye image to display the stereoscopic image. Thereby, the parallax of the stereoscopic image is adjusted, so as to enhance the synthesizing effect of the stereoscopic image created.

摘要： The invention provides an image processing apparatus for generating coordination calibration points. The image processing apparatus includes a subtracting module, an edge detection module and an intersection point generation module. The subtracting module subtracts a first image from a second image to generate a first subtracted image, and subtracts the first image from a third image to generate a second subtracted image. The edge detection module performs an edge detection process for the first subtracted image to generate a first edge image, and performs the edge detection process for the second subtracted image to generate a second edge image, wherein the first edge image includes a first edge and the second edge image includes a second edge. The intersection point generation module generates, according to the first and second edges, an intersection point pixel, serving as the coordination calibration point corresponding to the first edge and the second edge.
