The built-in DSP divides the screen into 225 (15 X 15) segments which are
specified into five detection windows. The integrated luminous intensity of
each window is continuously measured by weighing the value and the
average determines an accurate back light compensation. This type of BLC
is suitable for the applications that main object always locate at central area
of picture.
6.2 Histogram Calculated BLC
This intelligent BLC categorize the image into three parts (high-medium -low)
according to the brightness level of each pixel and calculate the histogram of
each part. With the integration of histogram of all three parts, the
microprocessor will determine the operation level of BLC. This type of BLC is
suitable for the areas where object will move around within the scene.
