Method and apparatus for production of an image captured by an electronic motion camera/sensor that emulates the attributes/exposure content produced by a motion camera film system

   
   

An electronically originated image is converted into a modified electronic image simulating an image originated from a film system and converted into an electronically displayed image. The technique employed is based on a set of electronic camera system spectral product curves that are substantially approximated by a linear combination of a set of spectral product curves characteristic of the film system. An image is captured having red, green and blue exposure signals resulting from these electronic camera system spectral product curves, and the red, green and blue exposure signals are then converted into a modified electronic image simulating an image originated from a film system and converted into an electronically displayed image. Because of the linear approximation between the spectral product curves, the conversion step can be performed by a matrixing operation.
