Minimizing a Data Pedestal Level in an Image Sensor

A system, comprising:

• a pixel array;
• processing circuitry operably connected to the pixel array and configured to receive pixel signals from the pixel array, wherein the processing circuitry includes one or more amplifiers;
• a temperature sensor;
• and
• a processor operably connected to the processing circuitry and the temperature sensor, wherein the processor is configured to dynamically determine an adjustment amount for a pedestal level based on at least one of:
• a temperature received from the temperature sensor;
• a gain of at least one amplifier in the processing circuitry;
• and
• a length of an integration time of at least one pixel in the pixel array.

A method of reducing a pedestal level used by an image sensor, the method comprising:

• receiving a subset of pixel signals in an image, wherein the subset of the pixel signals is associated with a single color;
• comparing a respective pixel signal in the subset of the pixel signals to a given pixel signal in the subset of the pixel signals to determine if a difference between the respective pixel signal and the given pixel signal is less than a first threshold;
• if the difference between the respective pixel signal and the given pixel signal is less than the first threshold, including the respective pixel signal in a calculation of an average of the pixel signals in the subset of pixel signals that are less than the first threshold, wherein the average comprises a replacement pixel signal;
• determining if at least one pixel signal in the subset of the pixel signals is less than a second threshold;
• if at least one pixel signal in the subset of the pixel signals is less than the second threshold, outputting the replacement pixel signal as a pixel signal;
• and
• if at least one pixel signal in the subset of the pixel signals is not less than the second threshold, outputting the given pixel signal in the subset of the pixel signals as the pixel signal.
