orthogonal may pass through the filter this light may be partially absorbed by the adjacent pixel rather than the pixel directly below the filter the lens 39 optical characteristics e g its f number or telecentricity may cause the portion of the light absorbed by the neighboring pixel to vary significantly microlenses located atop the color filters may reduce this complement of crosstalk electrical crosstalk results from the photocarriers which are generated from the image sensor moving to neighboring charge accumulation sites electrical crosstalk occurs in all image sensors including monochrome image sensor the quantity of crosstalk in carriers depends on the pixel structure collection areas size and intensity distribution each of these kinds of cross can be graphed and the optimum shift for the crosstalk reduction can be selected for example each of the spectral crosstalk optical crosstalk and electrical crosstalk can be separately viewed the different types of crosstalk can then be separately optimized fig7 shows system 2000 a typical processor based system modified to include an image sensor as depicted in fig4 as part of an imager device 2040 processor based systems exemplify systems of digital circuits that could include an image sensor examples of processor based systems include without limitation computer systems camera systems scanners machine vision systems vehicle navigation systems video telephones surveillance systems auto focus systems star tracker systems motion detection systems image stabilization systems and data compression systems for high definition television any of which could utilize the invention system 2000 includes central processing unit cpu 2010 that communicates with various devices over bus 2070 some of the devices connected to bus 2070 provide communication into and out of system 2000 illustratively including input output i o device.
