Optimized hybrid Bayer color filter array

An image sensor assembly, comprising:

• a lens assembly with a variable focal length;
• a color filter array comprising a plurality of non-overlapping regions, including a first region and a second region, configured to filter light received at a plurality of sensors, wherein the first region and the second region comprise color filter patterns further comprising a plurality of color filters arranged in an equal number of rows and columns, and wherein at least a portion of the color filters of individual patterns of the color filter patterns are different from other color filters of the individual patterns;
• the first region corresponding to a first image region of a telephoto range of a variable focal length lens and comprising one or more repetitions of a first color filter pattern, wherein individual repetitions of the one or more repetitions of the first color filter pattern filter light received at a first number of sensors;
• and
• the second region corresponding to a second image region of a wide angle range of the variable focal length lens and comprising one or more repetitions of a second color filter pattern, wherein individual repetitions of the one or more repetitions of the second color filter pattern filter light received at a second number of sensors, wherein the second number of sensors is different from the first number of sensors;
• wherein the first region corresponds to a first image circle of a telephoto range of the variable focal length of the lens assembly;
• wherein the second region corresponds to a second image circle of a wide angle range of the variable focal length of the lens assembly;
• and
• wherein the second number of sensors is greater than the first number of sensors.

A method, comprising:

• using a lens assembly with a variable focal length to project light onto a color filter array;
• filtering light received by a first region of a plurality of non-overlapping regions of the color filter array, wherein the first region comprises one or more repetitions of a first color filter pattern, wherein individual repetitions of the one or more repetitions of the first color filter pattern filter light received at a first number of sensors arranged in an equal number of rows and columns, and wherein at least a portion of the color filters of the first color filter pattern are different from other color filters of the first color filter pattern;
• filtering light received by a second region of the plurality of non-overlapping regions of the color filter array, wherein the second region comprises one or more repetitions of a second color filter pattern, wherein individual repetitions of the one or more repetitions of the second color filter pattern filter light received at a second number of sensors arranged in an equal number of rows and columns, and wherein at least a portion of the color filters of the second color filter pattern are different from other color filters of the second color filter pattern, and wherein the second number of sensors is different from the first number of sensors;
• wherein the first region corresponds to a first image circle of a telephoto range of the variable focal length of the lens assembly;
• wherein the second region corresponds to a second image circle of a wide angle range of the variable focal length of the lens assembly;
• and
• wherein the second number of sensors is greater than the first number of sensors.
