Patent ID: 8477091

Claim:
An information output unit that is connected to anyone of a first liquid crystal display unit, which displays an image based on inputted image information without applying gamma correction to the image information, and a second liquid crystal display unit, which displays an image based on inputted image information after applying gamma correction based on gamma correction information to the image information, the information output unit comprising: a first-gamma-correction-information storing unit that has stored therein first gamma correction information used for gamma correction applied to the image information; a second-gamma-correction-information storing unit that has stored therein second gamma correction information used for gamma correction applied to the first gamma corrected image information; a gamma correction unit that performs a correction results output operation irrespective of which of the first and second liquid crystal display units in connected to the information output unit; a control unit that outputs the second gamma correction information to either the first or second liquid crystal display unit connected to the information output unit irrespective of which of the first and second liquid crystal display units is connected to the information output unit wherein the correction result output operation comprises applying gamma correction based on the first gamma correction information to inputted image information to produce corrected image information and then outputting the corrected image information to the liquid crystal display unit connected to the connected information output unit, and wherein when the first liquid crystal display is connected to the information output unit, the first gamma correction information is used for gamma correction applied to the input image information, the first gamma correction information changes the input image information to image information suitable for display an image by the first liquid crystal display unit, and the second gamma correction information is not used for gamma correction, when outputted to the first liquid display unit, and wherein when the second liquid crystal display is connected to the information output unit, the second gamma correction information is used for gamma correction applied to the corrected image information, the second gamma correction information changes the corrected image information to image information suitable for display of an image by the second liquid crystal display unit.
