RECONFIGURABLE IMAGE SCALING CIRCUIT

摘要

A reconfigurable image scaling circuit includes a horizontal scalar, a bufferer, and a vertical scalar. The horizontal scalar is configured to generate a horizontally scaled image data by scaling an input image data horizontally. The bufferer includes a mapper and a plurality of buffers. The plurality of the buffers are configured to store the horizontally scaled image data. The vertical scalar is configured to generate an output image data by scaling the horizontally scaled image vertically using a vertical scaling method.

1. A reconfigurable image scaling circuit comprising:
a horizontal scalar configured to generate a horizontally scaled image data by scaling an input image data horizontally; a bufferer which includes a mapper and a plurality of buffers, the plurality of the buffers being configured to store the horizontally scaled image data; and a vertical scalar configured to generate an output image data by scaling the horizontally scaled image vertically using a vertical scaling method, wherein the horizontally scaled image data, which is stored in the plurality of the buffers, includes a plurality of first row data, wherein the output image data includes a second row data, wherein the vertical scaling method generates the second row data based on a plurality of reference row data included in the plurality of the first row data, wherein the mapper changes a mapping relation between the plurality of the reference row data and the plurality of the buffers based on a number of the plurality of the reference row data.
