Abstract:
A method to measure a brightness response of a camera comprises obtaining a plurality of brightness measurements and determining for one or more of the plurality of brightness measurements a captured brightness of the captured image. Obtaining each of the plurality of brightness measurements includes presenting to the camera at least one test sample having known brightness, capturing via the camera an image of the at least one test sample, and presenting to the camera at least one compensation sample having compensating brightness selected based on the known brightness of the at least one test sample. The at least one test sample and the at least one compensation sample are selectable and presentable in combination such that an average exposure interpreted by the camera is substantially the same for each of the plurality of brightness measurements.
