Image-color-correcting method using a multitouch screen

摘要

A method for correcting the color of an image using a multi-touch capable touch-screen of a digital device used for photo or video equipment. The method turns away from the traditional three ways color correction systems or slide system used for conventional color correction control device by effectively using movements of hands and the line of them. Accordingly, the number of controls for color correction of images may be reduced.

1. A method for correcting the color of an image using a multi-touch capable touch-screen, the method comprising:
sensing touch of three fingers on the surface of the touch panel, detecting each finger's input coordinates for each finger's position and setting the input coordinates of three fingers into a first set of coordinates; calculating the first center coordinates of the first triangle formed by the first set of coordinates; detecting each finger's changed input coordinate for each finger's changed position and setting the changed input coordinates of three fingers into a second set of coordinates, according to the movement of the each finger on the touch panel; calculating the second center coordinate of a second triangle formed by the second set of coordinates; calculating the center deviation distance between the first center coordinate and the second center coordinate; calculating triangle area size ratio between the area of first triangle formed by the first set of coordinates and the area of the second triangle formed by the second set of coordinates; and calculating average rotation value between the first triangle formed by the first set of coordinates and the second triangle formed by the second set of coordinates, wherein, Hue, Saturation and lightness of the image is altered based on the center deviation distance, the triangle area size ratio and average rotation value.
