values of the image to be imaged over 500 different digital levels, however. The entire histogram includes 1,024
values in the 10 bit image (in contrast to 256 values with 8 bits).
This means that a contrast adjustment can now be made for screen display without a reduction in quality. The 500
values of the output image are distributed over the 256 values of the 8-bit target image in such a way that optimum
contrast is the result. The large number of output values means that there are no gaps in the histogram.
Contrast adjustment with 10 bit output data
Note
This type of contrast adjustment can already be done in the camera when an image is digitized in 10 bits and
transferred in 8 bit. In this case, optimum utilization of the 8 bit data is also important for image processing.
