Abstract
An imaging system includes an array of pixel sensors and a mode control circuit. The array of pixel sensors is adapted to furnish logarithmically encoded indications of light intensities during a first mode and furnish linearly encoded indications of the light intensities during a second mode. The mode control circuit is adapted to selectively place the array in one of the first and second modes. The imaging system may include more than one array, and the mode control circuit may configure one of the arrays. The imaging system may include a camera, for example, that includes the array(s) and mode control circuit.
