Abstract: A method of tuning parameters for image signal processing is provided. The method includes capturing at least one raw image. The method further includes generating a first rendered image by rendering the raw image based on a first parameter value set, and generating a second rendered image by rendering the raw image based on a second parameter value set. The method further includes calculating a first image quality score set for the first rendered image, and calculating a second image quality score set for the second rendered image. The method further includes generating a third parameter value set based on the first parameter value set, the second parameter value set, the first image quality score set, and the second image quality score set.

Abstract: A method for tuning a plurality of image signal processor (ISP) parameters of a camera includes performing a first iteration. The first iteration includes extracting image features from an initial image, arranging a tuning order of the plurality of ISP parameters of the camera according to at least the plurality of ISP parameters and the image features, tuning a first set of the ISP parameters according to the tuning order to generate a first tuned set of the ISP parameters, and replacing the first set of the ISP parameters with the first tuned set of the ISP parameters in the plurality of ISP parameters to generate a plurality of updated ISP parameters.

Abstract: Design rules are described for a phase alternating shift mask for minimum chrome width and maximum segment length, where an embodiment employs during a cleaning process of the mask a megasonic power of 50 Watts at 1 MHz, and 30 Watts at 3 MHz. Some embodiments utilize an dry etch Carbon Tetrafluoride and Dioxygen based process. Other embodiments are described and claimed.
