Abstract
Systems and methods for improving target object visibility in captured images can include an imaging sensor for mounting on an aircraft at a fixed position and orientation. A predetermined portion of the aircraft can appear as a region of interest (ROI) at a predefined location across images captured by the imaging sensor. A processor can receive a first image signal from the imaging sensor and corresponding to a first image that includes the ROI. The processor can determine a first image intensity range of the ROI in the first image and a gain value for modifying the first image or a subsequent image. The processor can cause a second image signal, received from the imaging sensor, to be amplified using the gain value and cause the region of interest in a second image to have a second image intensity range different from the first image intensity range.
