Title:
METHOD FOR ADJUSTING COLOR TEMPERATURE OR WHITE BALANCE AND DEVICE THEREFOR
Document Type and Number:
Japanese Patent JP2978615
Kind Code:
B2
Abstract:
PURPOSE: To make the color of a picture almost equivalent to the color of a picture when the color is photographed under a constantly preferable standard light source by eliminating the influence of a light at the time of a color picture photographing from the inputted color picture.
CONSTITUTION: This device is provided with an input means 1 converting the combination of information sets composed of three elements of a color having correlation into a relevant electric signal, a 1st conversion means 21 converting the electric signal from the input means 1 into the information set minimizing the correlation, a 2nd conversion means 22 converting an output from the 1st conversion means 21 into information sets under a standard light source by using an inverse transfer matrix obtained through the learning under the preferred standard light source, a storage means 3 storing the inverse transfer matrix processing minimized output correlation under the standard light source, and an output means 4 outputting the output from the 2nd conversion means 22 as an optional output signal.
