Abstract:
1. A method comprising: reading a first intensity value from a first input cell in a particular row of input cells that contains intensity values from a single horizontal pixel line of a distorted input image, wherein the first intensity value is for a first input pixel; determining that the first input pixel maps to a first output pixel of an undistorted output image; determining that the first output pixel corresponds to a first output line buffer cell in a first output line buffer within a set of output line buffers; setting the first output line buffer cell to a value that is based at least in part on the first intensity value, thereby causing said first output line buffer to be only partially filled; before reading any intensity value from any other row of input cells, reading a second intensity value from a second input cell in said particular row of input cells, wherein the second intensity value is for a second input pixel; determining that the second input pixel maps to a second output pixel of said undistorted output image, on a separate pixel row of said undistorted output image than a pixel row of said undistorted output image on which said first output pixel occurs; determining that the second output pixel corresponds to a second output line buffer cell in a second output line buffer, separate from said first output line buffer, within said set of output line buffers; and setting the second output line buffer cell to a value that is based at least in part on the second intensity value, thereby causing said second output line buffer to be only partially filled while said first output line buffer remains only partially filled.
