1. A system in a motor vehicle for real-time adjustment of image quality parameters for images taken by image sensors, the system comprising:
an HMI (human machine interface) comprising a display screen in the motor vehicle;
an optical imaging device on the motor vehicle;
a controller, the controller configured to:
acquire an image frame from the optical imaging device, the image frame having a fixed-pixel region that defines a region-of-interest for viewing on the display screen of the HMI, the region-of-interest including pixels representing an environment exterior to the motor vehicle and pixels representing one or more external components of the motor vehicle;
determine a boundary for the region-of-interest in the fixed-pixel region that excludes the pixels representing the one or more external components of the motor vehicle by applying a morphological processing algorithm;
based on the boundary, determine a modified fixed-pixel region by removing the pixels representing the one or more external components of the motor vehicle;
alter a tone-mapping parameter to an altered tone-mapping parameter based on statistics of pixels in the modified fixed-pixel region;
alter an auto-exposure parameter to an altered auto-exposure parameter based on statistics of the pixels in the modified fixed-pixel region; and
provide the altered tone-mapping parameter and the altered auto-exposure parameter to the optical imaging devices for use with subsequent image frames; and
wherein the optical imaging devices is configured to apply the altered tone-mapping parameter and the altered auto-exposure parameter produce an image of the region-of-interest that is tuned based on the altered tone-mapping parameter and the altered auto-exposure parameter;
wherein the display screen of the HMI is configured to display the image of the region-of-interest that is tuned based on the altered tone-mapping parameter and the altered auto-exposure parameter.
