    摘要: A data processing apparatus having a small hardware size and performing lens correction includes a seed memory, a gain memory, and a decoder. The seed memory stores a plurality of encoded gain values forming an A*B seed matrix; the gain memory stores a plurality of decoded gain values forming an M*N grid matrix. The decoder is connected between the seed memory and the gain memory and performs vertical recursive rear polynomial (RNP) decoding before performing horizontal RNP decoding after a second time. Accordingly, the decoder may decode the M*N grid matrix from the A*B seed matrix by performing the row directional RNP decoding and the column directional RNP decoding by turns.

    摘要: For auto-focusing of a focusing lens within an image sensing system, an N-bin luminance histogram is generated by a digital signal processor from an image. A microprocessor determines a type of the image from the N-bin luminance histogram. The microprocessor also determines a focus position using a first set of at least one focus value if the image is determined to be of a first type. The microprocessor also determines the focus position using a second set of at least one focus value different from the first set if the image is determined to be of a second type.

    摘要: The lens includes a plurality of lens layers, each lens layer being axi-symmetric and having an extended depth of focus to focus light in a corresponding section of a focal curve in the form of a straight line located on an optical axis. In the optical system, light is focused on an optical axis to obtain a clear image in a wide distance range between a camera and an object. The optical system has a point spread function that is simpler and more symmetric. That is, the optical system provides improved continuity of a lens surface and easiness and flexibility in optical designing.
