Method of viewing virtual display outputs
View Patent ↗A method for viewing a simulated light output generated for a first display on a second display includes a variety of steps. First, the simulated light output is generated based on qualities of the first display. Next, the simulated light output is compensated for color differences, temporal differences, luminance differences including gamma difference, and differences in viewing environment between the first and the second display, in real-time. Then, the simulated light output that has been compensated for the differences and for viewing environment is output for the second display.
1. A method for viewing a simulated light output generated for a first display type on a second display, the method comprising:
receiving an image source;
selecting via a display model selector a display model of the first display type;
a processor generating for the selected display model the simulated light output based on qualities of the first display type by converting the image source to a pre-gamma RGB image, and converting the pre-gamma RGB to the simulated light output using matrix manipulation, wherein gamma is a parameter that represents the non-linear transfer function between the input signal and output light intensity;
the processor compensating the simulated light output for a viewing environment of the second display; in real time based on the viewing environment and gamma compensation, in which the viewing environment includes color and brightness of surroundings and ambient light of the second display and virtually reality created viewing environment;
