HQV Benchmark 2.0 Analysis – ATi, nVidia and Intel

The fourth chapter focuses on analysing the video processor’s ability to enhance the image through ‘adaptive processing’.

The first set of results examines contrast enhancement features. These results concentrate on expansion of image contrast ratios while maintaining detail in dark and white sectors. This test is not targeting image sharpness, detail, flicker or noise, just contrast enhancement.

All the tests are combined into one result, giving a total figure. The score is based on evaluating the sequence of images. Note that fine detail would not be observable on small screens or displays which are not fully HD compliant.

In this particular test we look for overall reduction in contrast to expose greater detail, especially with the black fur of the cat. Bright areas in the scene such as the white cat and background textures should also have improved detail.

Contrast Enhancement: White and Black cats (Score either  5, 2 or 0)
Overall contrast is reduced so more detail is visible in the bright and dark areas. – Scores 5
Detail is improved on either one of the dark or bright area without loss of detail in the other area. – Scores 2
Overall contrast remains the same or is increased and detail is loss in either the bright or dark areas. – Scores 0
