Color space matching of video signals

摘要

A system for color space matching a plurality of signals is provided. The system can include a first and second sources operably connected to a first and second inputs, respectively. The first and second inputs can be operably connected to a switch (140). An external device identification (EDID) module (155) can be operably connected to the switch. A controller (150), having a plurality of display modes, can also be operably connected to the switch. Each of the plurality of display modes can have a corresponding unique EDID data structure stored in the EDID module, thereby providing a plurality of unique EDID data structures within the EDID module. The EDID module can select a single unique EDID data structure based upon the color space format of the second signal (125), and in response to the selection, the first source (190) can convert the first color space of the first signal (110) to the second color space format.

1. A system for color space matching a plurality of signals comprising:
a first input (105) operably connected to a first source (190), the first input operable to receive a first signal (110) having a first color space format; a second input (120) operably connected (125, 130) to a second source (195), the second input operable to receive a second signal (125) having a second color space format; a switch (140) operatively coupled to the first input and the second input; a controller (150) operatively coupled to the switch, the controller having a plurality of display modes;
wherein each display mode is associated with a unique External Device Identification (“EDID”) data structure, thereby providing a plurality of unique EDID data structures;wherein the plurality of unique EDID data structures are disposed in, on, or about an EDID module (155) operatively coupled to the switch;wherein the EDID module selects a single unique EDID data structure based upon the color space format of the second signal (125); andwherein, responsive to the selection of the single unique EDID data structure by the EDID module, the first source converts the first color space format to a third color space format; and a display output (165) operably coupled to the controller;
wherein an sRGB EDID data structure is selected when the first color space format is selected from the group of color space formats consisting of: an sRGB color space and a YUV color space; andwherein an xvYcc EDID data structure is selected when the first signal is in xvYcc color space format; providing a second signal (125) having a second color space format from a second signal source (195) to a second input (120);
wherein the second input is operatively coupled to the HDMI switch;wherein the second signal source is disposed in, on, or about the computer housing;wherein one or more sRGB to xvYcc conversion charts are disposed in, on, or about the second signal source; andwherein the second color space format is an xvYcc color space format when the xvYcc data structure is selected.
