Methods and devices for processing image frames is described. The techniques presented herein leverage known characteristics of the optical transfer component in order to modify the resource allocation for rendering the subset of pixels whose contribution to the final rendered image is less than a contribution threshold. Thus, in situations where the deflection of light from the lens may impact the contribution of the one or more subset of pixels of an image frame towards the final rendered image, the image processing techniques presented here may either omit or deprioritize the identified subset of pixels in order to conserve valuable resources (e.g., dedicate less processing time and memory to rendering the identified subset of pixels).
