Patent ID: 7277575

Claim:
A system for effectively performing an image data transformation procedure, comprising: an electronic camera device configured to capture primary image data corresponding to a photographic target; and a transformation manager configured to convert said primary image data into secondary image data by utilizing transformation parameters that are optimized to minimize noise characteristics in said secondary image data, said primary image data being in an RGB format that is converted into said secondary image data in a YCbCr format by said transformation manager during said image data transformation procedure, said transformation parameters being optimized by evaluating an optimization metric that is evaluated in a linear L*a*b* color space to minimize said noise characteristics in said secondary image data, standard noise deviations above and below an average L* value being calculated for each color patch from a representative patch set, said standard noise deviations being utilized to calculate noise variance values for each of said color patches according to a formula: NV =( SND ) 2 where SND is one of said standard noise deviations, and NV is a corresponding one of said noise variance values used to calculate said optimization metric.
