Claim One:
1. A method for filtering image information to generate a dithered image, comprising: receiving input image information, the input image information corresponding to an image generated using a first array comprising a first number of small pixels; generating intermediate image information from the input image information, the intermediate image information generated to produce the image using a second array comprising a second number of large pixels, the second number less than the first number, an actual frequency response associated with the image produced using the second array exhibiting one or more aliasing effects, the actual frequency response indicating a frequency response of a device producing the image using the second array; repeating the following steps for a plurality of iterations to generate updated image information from the intermediate image information: filtering the intermediate image information according to a frequency compensating function in order to adjust the actual frequency response to at least approximate a desired frequency response, the desired frequency response reducing the one or more aliasing effects; and generating sub-image information from the updated image information, the sub-image information corresponding to a projected dithered image.
