An imaging system disables pixel integration for images within frames that are identified as moving while enables pixel integration for images that are not moving. The system may implement a frame-averaging type of integration or recursive types of frame integration, or may refrain from performing frame integration. On a pixel-by-pixel basis, the system may compare a pixel from frame memory with a corresponding pixel of an input frame and may disable pixel integration for the pixel when a difference between the compared pixels exceeds a threshold. One of the integration processes may be performed on the pixels when the difference does not exceed the threshold. When frame integration is disabled or de-selected (e.g., for pixels having motion), the frame memory may be bypassed and a self-integration may be performed with corresponding pixels from a current frame effectively resulting in no integration. Some embodiments may use multiple thresholds, and may use different integration algorithms depending on conditions within a scene.
