摘要： Disclosed embodiments utilize MIP techniques to determine optimum bit sequences that minimize PWM artifacts. The problem would first be restructured and redefined into a form suitable for MIP. An objective function designed to minimize PWM artifacts would allow for evaluation of resulting bit sequences in order to determine optimality. Constraints (that relate the inputs and variables) are developed. These constraints would determine whether a particular bit sequence can be used on a given system, and whether a particular bit sequence would satisfy any user defined rules. Once these are determined, an MIP solver would generate an optimized bit sequence(s). Only bit sequences that satisfy the constraints would be evaluated using the objective function, allowing for a quicker determination of a solution. This MIP solution may be generated quickly, allowing for a shorter production period while still optimizing the bit sequences to minimize PWM artifacts.

摘要： According to one embodiment, a method for displaying an image in a light processing system includes receiving an image to be displayed. The method also includes generating a light from a light source. The method further includes receiving the light at a spatial light modulator having a group of pixels. The method further includes displaying the image along an optical path. The method further includes automatically defocusing the image by adjusting at least one of a group of optical elements along the optical path, thereby reducing pixel noise in the displayed image.

摘要： An input signal having a first sampling rate is converted to an output signal having a second sampling rate. This is done by obtaining an intermediate sampling value from the input signal and filtering the intermediate sampling value to obtain the output signal. The intermediate sampling value corresponds to a sample taken at the second sampling rate on a continuous-time representation of the input signal.

摘要： According to one embodiment, a projection system includes a color wheel operable to filter light into a passed component and a reflected component. The projection system also includes a digital micromirror device comprising a plurality of micromirrors each operable to receive the passed component and the reflected component. Each micromirror is selectively positionable to direct, at approximately the same time, the passed component and the reflected component to desired locations. The projection system also includes an optical system operable to direct the passed component and the reflected component from the color wheel to the digital micromirror device at approximately the same time.
