<p>A gradation image capture is used to test one or more image sensors. The integration periods for the rows of pixels in the array, or for groups of rows of pixels, are varied during each single still frame image capture. The rows of pixels are reset either simultaneously or successively to a predetermined level, and then begin accumulating charges. The rows of pixels, or groups of rows of pixels, are read out at different times to vary the integration periods of the pixels. Some or all of the signals are analyzed or measured to detect any design or manufacturing problems.</p> |
