摘要： A CMOS image sensor or other type of image sensor comprises an array of pixels arranged in rows and columns, with the columns being separated into groups each comprising two or more columns that share a common output. The image sensor further comprises sampling and readout circuitry that includes, for each group of columns in the pixel array, a corresponding set of two or more column circuits. The sampling and readout circuitry is configured to sample the common output for each group of columns independently into one of the column circuits associated with that group, and to read out the common output for each group of columns as previously sampled into another of the column circuits associated with that group. The image sensor may be implemented in a digital camera or other type of image capture device.

摘要： An apparatus and method are implemented in a halftone printing system utilizing logic blocks that permit a halftone elliptical dot to be represented by an elliptical envelope that is formed from a combination of straight lines that are drawn from tangent points, on the outer periphery of the elliptical dot, through reference axis for the elliptical dot. The intersection points of the tangent lines on the reference axis define the size (density) of the elliptical dot. Storing the intersect points as sets of values for each size elliptical dot provides a unique representation set that is used to reconstruct a selected elliptical dot size for printing a halftone image.
