Abstract
A non-linear conversion capability within an on-chip, per-column analog-to-digital converter (ADC) is provided to expand a compressed analog signal such that the resulting digital output that has a predetermined (linear or non-linear) mapping with respect to input brightness level of an incoming light signal to a row of pixels. The predetermined mapping may also be provided by a non-linear amplifier coupled to a linear or non-linear ADC and a resulting compressed non-linear digital representation at the output of the ADC is substantially linearized by an on-chip or an off-chip look-up table (LUT).
