Claim One:
1. An image processing device comprising: a full width array image sensor including a plurality of pixel sensors, each pixel sensor providing an output, the full width array image sensor scanning an image on a recording medium; a plurality of temperature sensors disposed along a length of the image sensor, each of the temperature sensors providing an output; and a temperature calibration unit in communication with the temperature sensors, the temperature calibration unit configured to generate a calibration output comprising temperature compensated factors based on the outputs of the temperature sensors; wherein the temperature calibration unit: formulates a calibration equation that calibrates pixel sensor-to-pixel sensor offset and gain variations for the image sensor; obtains the real-time temperature output of each of the plurality of temperature sensors; determines the temperature of each of the pixel sensors of the image sensor based upon the real-time temperature output of the plurality of temperature sensors; determines calibration factors comprising a temperature dependent gain factor, m i (t i ), and a temperature dependent offset factor, b i (t i ); and generates the calibration output based upon the calibration factors and the calibration equation for each pixel sensor based upon a series of temperature points for each pixel sensor of the image sensor.
