Abstract
A dual modulator display has a first array of pixels that illuminates a second array of pixels with a pattern of light. The second array of pixels modulates the pattern of light to yield an image. A method for determining control values for pixels of the first array of pixels begins with an initial set of control values and refines the control values. The control values may be refined one at a time. Images may be displayed in real time.
