Abstract:
The embodiments described below include systems, methods, and computer storage mediums for blending image assets based on changes in a zoom level. An exemplary method includes determining an image asset from a collection of image assets, wherein the image asset is determined as a function of the zoom level. When the zoom level meets a threshold zoom level, a color corrected image asset is determined from the collection of image assets. The color corrected image asset is determined as a function of the zoom level and a color correction profile. The image asset and the color corrected image asset are blended, where the blending includes applying a first coefficient value to the image asset and a second coefficient to the color corrected image asset. Each of the first and second coefficient values may be determined as a function of the difference between the zoom level and the threshold zoom level.
