Abstract
A camera system processes images based on image luminance data. The camera system includes an image sensor, an image pipeline, an encoder and a memory. The image sensor converts light incident upon the image sensor into raw image data. The image pipeline converts raw image data into color-space image data and calculates luminance levels of the color-space image data. The encoder can determine one or more of quantization levels, determining GOP structure or reference frame spacing for the color-space image data based on the luminance levels. The memory stores the color-space image data and the luminance levels.

-20. (canceled)
A camera system, comprising:
- an image sensor configured to convert light incident upon the image sensor into raw image data;
- a processing apparatus that controls operation and functionality for the camera system;
- and
- a non-transitory computer readable apparatus comprising a storage medium having a plurality of instructions stored thereon, the plurality of instructions, when executed by the processing apparatus, is configured to produce encoded image data by:
- conversion of the raw image data into color-space image data;
- calculate luminance levels of the color-space image data;
- store the color-space image data and the calculated luminance levels of the color-space image data;
- retrieve the stored color-space image data and the calculated luminance levels;
- determine quantization levels of the color-space image data based on the calculated luminance levels;
- encode the color-space image data using the determined quantization levels to produce the encoded image data;
- and
- store the encoded image data.
