Frame Averaging
Captures from 1 to 256 frames, at any image resolution; accumulates the unprocessed/uncompressed pixel data in software and averages the accumulated pixel data by the number of frames captured.
Advantages
Increases the Signal-to-Noise Ratio in low-light images, by up to 16x with no loss of definition (up to the camera’s rated maximum of 52 dB). The rate of S/N is calculated by taking the square root of the number of frames captured (i.e. 256 frames captured = 16x S/N). Reduces the noise in low-light, low signal images
Increases the sensitivity of the camera up to 10x (from 3 lux to .3 lux),
Histogram Equalization
Performs histogram equalization on the 16-bit data (48-bit RGB) of accumulated frames. Only 2 accumulated frames are necessary to achieve 16-bit data.
Advantages
Significantly enhances low light and low contrast images through better distribution of contrast.
Adjustable Contrast Expansion
Performs expansion of the histogram, on the 16-bit data (48 bit RGB) of accumulated frames, centered on each color channel’s mean value.
Advantages
Significantly increases/enhances the contrast of low light and/or low contrast images while preserving the color balance of the image.
Adjust Histogram Level
Clips the highlight (bright) and shadow (dark) points of the histogram and expands the histogram to the best contrast.
Advantages
Significantly increases/enhances the contrast in images with the limitation that this techniques may slightly distort the color balance of the image.
