Digital circuitry is provided that periodically reads at least one bit of digital counters associated with pixels of an image sensor. When the read bit(s) of a particular digital counter decrease between subsequent reads, then the digital circuitry increments an overflow counter associated with the particular digital counter. The value of each of the overflow counters of the digital circuitry are used with the corresponding values of the digital counters to generate pixel values for a frame (also referred to as an image).

Increasing dynamic range of digital pixels by utilizing polling during integration

Methods and apparatus for preventing solar damage, and other heat-related damage, to uncooled microbolometer pixels. In certain examples, a thermochroic membrane that becomes highly reflective at temperatures above a certain threshold is applied over at least some of the microbolometer pixels to prevent the pixels from being damaged by excessive heat.

Thermal protection mechanisms for uncooled microbolometers

Methods and apparatus for preventing solar damage, and other heat-related damage, to uncooled microbolometer pixels. In certain examples, at least some of the pixels of an uncooled microbolometer are configured with a bimetallic thermal shorting structure that protects the pixel(s) from excessive heat damage. In other examples a thermochroic membrane that becomes highly reflective at temperatures above a certain threshold is applied over the microbolometer pixels to prevent the pixels from being damaged by excessive heat.
