Patent ID: 6965401

Claim:
A white balance correcting device for correcting white balance of a picked-up image signals, comprising: an image pickup device which picks-up image signals of an image pick-up plane; a dividing part which divides a scope of the image pick up plane into a plurality of blocks; a peak value acquiring part which acquires a peak value of brightness and color signal values corresponding to the peak value of brightness obtained in each of all of the plurality of blocks divided by said dividing part; an average value calculating part which calculates an average value of brightness and average values of color signal values obtained in each of all of the plurality of blocks divided by said dividing part; a comparison part which makes comparison between brightness information of the average value and the peak value; a selection part which selects either of the values obtained by said average value calculating part or the values obtained by said peak value acquiring part according to comparison result by said comparison part; a white balance control part which controls white balance on the basis of the values selected by said selection part; and wherein said comparison part computes comparison between a first integral value obtained by integrating average values obtained by said average value calculating part and a second integral value obtained by integrating peak values obtained in the scope by said peak value acquiring part, and, wherein said selection part selects the values obtained by said peak value acquiring part if the second integral value is not less than a predetermined number of times the first integral value, and said selection part selects the value obtained by said average value calculating part if the second integral value is less than the predetermined number of times the first value.
