A method for calibrating a projector display system, said projector display system comprising a light source, a controller, said controller receiving input image data and outputting control signals, a premod modulator receiving control signals from said controller and light from said light source, a blurring optical system receiving light from said premod modulator, and a primary modulator receiving control signals from said controller and light from said blurring optical system, the method comprising: receiving input image data; computing from the input image data a halftone image, the halftone image being represented on a premod pixel grid; applying a light field model on the halftone image, said light field model based on a PSF model of said blurring optical system, to provide an actual light field image; computing from the actual light field image a primary image for said primary modulator, wherein the primary image is represented on a primary pixel grid; displaying a screen image from said primary modulator using the computed primary image, the screen image being represented on the primary pixel grid; characterized by capturing said screen image with an image capture device; registering the captured screen image with the premod pixel grid; comparing said registered captured screen image with said input image data; if there are differences greater than a desired amount, then computing a correction to said PSF model; and applying an improved PSF model comprising said PSF model corrected by said correction for further calibration, wherein computing the corrections of saidPSF model comprises: - dividing the registered screen image by the computed primary image to produce an estimated light field image; - comparing the estimated light field image to the actual light field image; - estimating a light field error based on the comparison of the estimated light field image to the actual light field image; and - deconvolving the light field error estimate with the actual halftone image to calculate the PSF correction forming the PSF model to be applied. receiving input image data; computing from the input image data a halftone image, the halftone image being represented on a premod pixel grid; applying a light field model on the halftone image, said light field model based on a PSF model of said blurring optical system, to provide an actual light field image; computing from the actual light field image a primary image for said primary modulator, wherein the primary image is represented on a primary pixel grid; displaying a screen image from said primary modulator using the computed primary image, the screen image being represented on the primary pixel grid; characterized by capturing said screen image with an image capture device; registering the captured screen image with the premod pixel grid; comparing said registered captured screen image with said input image data; if there are differences greater than a desired amount, then computing a correction to said PSF model; and applying an improved PSF model comprising said PSF model corrected by said correction for further calibration, - dividing the registered screen image by the computed primary image to produce an estimated light field image; - comparing the estimated light field image to the actual light field image; - estimating a light field error based on the comparison of the estimated light field image to the actual light field image; and - deconvolving the light field error estimate with the actual halftone image to calculate the PSF correction forming the PSF model to be applied.
