1. A computer implemented method to display information in an image, comprising: accessing an image in a memory, the image comprising pixels, each pixel having an image value; identifying a region in the image, the region having a centerline and outer edges and encompassing a plurality of pixels of the image; identifying a function that varies from an initial value at the region's centerline to a final value at an outer edge of the region; determining, for at least some of the pixels in the region— the pixel's image value, a location of the pixel, a first value for the pixel based on the function and the pixel's location, a tone map value for the pixel based on a tone map function and the pixel's image value, and a region value for the pixel based on the pixel's image value, the pixel's tone map value and the pixel's first value; updating, in the memory corresponding to the region, the image value of each pixel with the pixel's corresponding region value; rendering, after updating, information into the memory corresponding to the region to generate a revised image; and displaying the revised image on a display device.
