Compression of coordinate locations of defective pixels on an imaging sensor

A computer-implemented method for encoding a coordinate location, the computer-implemented method comprising:

• receiving, at location encoding circuitry, the coordinate location, wherein the coordinate location is associated with a location in a coordinate system of an imaging sensor;
• determining a sequential distance between the coordinate location and a previous coordinate location, wherein the sequential distance indicates a number of positions in a sequential order between the coordinate location and the previous coordinate location;
• determining a step size based on a plurality of coordinate locations;
• determining a coordinate location encoding associated with the coordinate location based on a comparison of the sequential distance to the step size;
• and
• writing the coordinate location encoding to a one-time programmable memory device associated with the imaging sensor.

An imaging sensor, comprising:

• a two-dimensional array of pixels;
• a one-time programmable memory device;
• and
• an apparatus comprising:
• location encoding circuitry configured to:
• receive a coordinate location associated with a location of a pixel in a coordinate system corresponding to the two-dimensional array of pixels;
• determine a sequential distance between the coordinate location and a previous coordinate location, wherein the sequential distance indicates a number of positions in a sequential order between the coordinate location and the previous coordinate location;
• determine a step size based on a plurality of coordinate locations;
• determine a coordinate location encoding associated with the coordinate location based on a comparison of the sequential distance to the step size;
• and
• write the coordinate location encoding to the one-time programmable memory device.
