摘要： In acquiring and reproducing an image, my method and apparatus correct for spurious gray background. Image brightness is sensed in multiple regions of an original image, to provide a corresponding multiplicity of signals for use in reproducing the image. In response to the multiple signals, a corresponding multiplicity of corrected signals is provided by adjusting each signal. The amount of adjustment depends on the size of the signal, and preferably includes jitter ― i. e., a random component. Preferably the random component is partially smoothed. The multiple corrected signals are used in reproduction of the image. Preferably the dependence of adjustment on signal size is a multivalued monotonic function. Preferably the function increases the brightness of image regions that are already relatively more bright, in comparison with image regions that are relatively less bright. Preferably the signals represent relative amounts of black, or darkness of a chromatic color; and for each signal a choice is made automatically between the greater of (1) zero and (2) a corresponding one of the multiple signals.
