Prevention of highlight clipping

A specially-configured hardware system configured to:

• access an image from an image sensor, the image comprising image portions, at least some of the image portions comprising color channels;
• determine, for a color channel of an image portion of the image, an adjustment value to apply to the color channel to correct for a color irregularity, the color channel comprising pixels, each pixel having a pixel value between zero and a maximum saturation value;
• determine, for a pixel of the color channel, a corrected adjustment value based on a difference between twice the pixel value of the pixel and the maximum saturation value;
• in response to a determination that the adjustment value as applied to the pixel of the color channel is larger than the corrected adjustment value, apply the adjustment value to the pixel to produce an adjusted color channel;
• in response to a determination that the adjustment value as applied to the pixel of the color channel is smaller than the corrected adjustment value, apply the corrected adjustment value to the pixel to produce an adjusted color channel;
• and
• generate a modified image based on the adjusted color channel.

A method for processing an image captured by a camera comprising:

• accessing an image from an image sensor, the image comprising image portions, at least some of the image portions comprising color channels;
• determining, for a color channel of an image portion of the image, an adjustment value to apply to the color channel to correct for a color irregularity, the color channel comprising pixels, each pixel having a pixel value between zero and a maximum saturation value;
• determining, for a pixel of the color channel, a corrected adjustment value based on a difference between twice the pixel value of the pixel and the maximum saturation value;
• applying a larger of the adjustment value as applied to the pixel and the corrected adjustment value to produce an adjusted color channel;
• and
• generating a modified image based on the adjusted color channel.
