Moving color test pattern

摘要

Test patterns and associated techniques for testing the fidelity of color processing are disclosed. One set of embodiments provide a test pattern that exhibits a large number of spatial interactions (e.g., edges) between colors corresponding to triples of constant value RGB primaries that incorporate a specific primary. Another set of embodiments provide an animated sequence of test patterns that exhibit temporal interactions between the colors identified above. Yet another set of embodiments provide a test pattern comprising a plurality of zones, where distinct subsets of the zones are configured to exhibit independent visual changes in response to adjustments of specific color processing controls. Using these test patterns, users may more easily test the fidelity of color processing (such as color dematrixing), and may more easily calibrate color processing controls accordingly.

主权项

1. A method for testing the fidelity of color processing, the method comprising:
receiving a first test signal representing a first test pattern comprising colors, wherein the first test signal defines:
(a) a first plurality of colors that appear in the first test pattern, the first plurality of colors including at least three colors, each of the first plurality of colors including a predetermined primary and filling contiguous regions in the first test pattern, wherein each of the first plurality of colors is a different combination of intensities of primaries that include the predetermined primary; and(b) a first plurality of edges between the contiguous regions of the first plurality of colors in the first test pattern, wherein, for each unique pair of colors in the first plurality of colors, there exists, in the first plurality of edges, at least one edge between contiguous regions of the unique pair of colors; and causing the first test pattern to be outputted, wherein the outputted first test pattern is generated based on the first test signal, and wherein the outputted first test pattern exhibits a second plurality of colors distinct from the first plurality of colors.
