Abstract
Image sensors, imaging systems, and methods for eliminating blooming artifacts in high dynamic range imaging. The image sensor includes a pixel array and a controller. The controller is configured to detect that a first pixel signal is at or below a barrier value. The first pixel signal is generated during a first exposure. The controller is also configured to compare neighboring pixel signals to the barrier value. The controller is further configured to determine a first image value for the center pixel based on a second pixel signal when at least one of the neighboring pixel signals is above the barrier value. The second pixel signal is generated during a second exposure that is shorter than the first exposure. The controller is also configured to set the first image value to the first pixel signal when each of the neighboring pixel signals is at or below the barrier value.
