Abstract: The invention relates to a CMOS image sensor that an be embedded in portable imaging systems. This high spatial resolution and low bit resolution CMOS area image sensor not only enables portable imaging systems such as cellular fax phone, portable copy machines, barcode reader, but also it can be fabricated in standard digital CMOS processes, particularly at 0.35 micron and below. This invention also discloses several portable imaging systems using such a CMOS image sensor. This invention further discloses a CMOS image sensor that has variable spatial resolution and bit resolution. Starting as a high spatial resolution low-bit resolution image sensor, the high bit-resolution is achieved by combining information from a group of nearest-neighbor pixels into a single super-pixel via spatial oversampling. This variable CMOS image sensor can be used in a multiple function imaging device for both document and video imaging, or photography.

Abstract: An imaging apparatus (10) for forming images from digital data, typically for printing or projection, the apparatus employing a spatial light modulator (30). The spatial light modulator (30) has a mounting (70) that is flexible in at least one direction in the plane that contains the surface of the spatial light modulator (30). An actuator (80) moves the mounting (70) at a speed that is at least a multiple of the refresh rate of the spatial light modulator (30), causing the movement of the spatial light modulator (30) to effect dithering of output pixels. This enlarges the effective pixel size to improve fill factor and reduce pixelization anomalies.
