Abstract:
An apparatus and method for performing screen captures on display devices are disclosed herein. The method includes receiving a screen capture command, determining pixel values of rows of the display device based on the screen parameters, obtaining framebuffer parameters from a framebuffer of the display device, the framebuffer parameters comprising pixel values of rows of the framebuffer, determining whether pixel values of the rows of the framebuffer are substantially equivalent to the pixel values of the rows of the display device, processing screenshot data read from the framebuffer based on the pixel values of the rows of the screen when the pixel values of the rows of the framebuffer are not substantially equivalent to the pixel values of the rows of the screen, and creating a file comprising the screenshot.
