Title: Image display device
Inventor: OGUSHI YOICHI
IPC: H04N5/202
Filed: 1994-06-20
Abstract: PURPOSE:To conduct gamma correction for fine contrast independent of a fixed table by classifying luminance signals of inputted images for a prescribed range and comparing their frequency distribution with a reference one so as to generate correction data. CONSTITUTION:An inputted luminance signal is A/D-converted and luminance data for one field are stored in a memory 3, and a luminance level detection section 5 detects a luminance level. A luminance classification section 6 classifies the signals for each luminance range and a histogram generating section 7 generates the frequency distribution. An arithmetic section 8 subtracts each frequency in a black/white level from the entire frequencies to calculate the frequency of a median level and calculates the frequency difference between the minimum frequency and the reference frequency. A characteristic extract section 9 compares frequencies of black/median and white levels to extract a minimum and a highest luminance range. A correction data generating section 10 adds the frequency difference calculated by the arithmetic section 8 to the highest luminance to decide a deflection point thereby generating correction data of the luminance level. A control section 4 allows an addition/subtraction circuit 12 to make addition/subtraction to luminance signal data read from the memory 3 based on the correction data at the end of blanking period.
