摘要: A system and method for correcting image data. Embodiments of the present invention provide image correction to overcome various lens effects, optical crosstalk, and electrical crosstalk. In one embodiment, the method includes accessing, within an electronic system, a plurality of control points for a patch of a spline surface and calculating a plurality of intermediate control points corresponding to a row of pixels of the patch. The method further includes receiving a pixel of an image and correcting the pixel based on the plurality of intermediate control points in streaming scanline column-wise or row-wise order.

摘要: A system and method for correcting image data. Embodiments of the present invention provide calibration and image correction to overcome various lens effects including lens shading and lens imperfections. In one embodiment, the correction of image data is performed via utilization of a spline surface (e.g., Bezier surface). The use of spline surfaces facilitates efficient hardware implementation. The image correction may be performed on a per channel and illumination type basis. In another embodiment, the present invention provides a method for determine a spline surface to be used for calibrating an image signal processor to be used in correcting image data.
