Patent ID: 8654192

Claim:
A method, comprising: receiving a digital picture file of a film video that is modeled to determine how the film video will appear on-screen before the film video is developed; estimating initial pixel values of an inter-image effects array that is utilized with an analytical model to tune effects of spectral dye density curves to determine output pixel values of the digital picture file; determining the output pixel values based, at least in part, on the initial pixel values and the inter-image effects array with the analytical model that comprises: modeling the digital picture file to determine a spectral exposure of a negative film for the film video; modeling a recorder light spectrum of a recorder that is used to record the negative film based on the spectral exposure to determine a spectral transmittance of the negative film; modeling printing data that represents the negative film printed onto a positive film to determine a printer light spectrum; modeling a spectral transmittance of the positive film based on the printer light spectrum; modeling a film projector to determine a spectral power distribution of projector light that projects the positive film as the film video on-screen; and generating a digital preview of the film video based on a look-up table of the output pixel values that are said determined with the analytical model.
