Stacked Image Sensor Charge Collection Timing Control

The patent applies dynamics by making the charge collection time period variable rather than fixed. The control unit dynamically adjusts the charge collection time period for each pixel layer based on analysis of object information such as movement and distance. This allows the system to optimize signal quality for each layer adaptively, resolving the contradiction between using multiple layers for increased information quantity while maintaining signal reliability.

The patent applies segmentation by dividing the pixel array into multiple stacked pixel layers, each with independent charge collection time period control. The control unit separately manages the charge collection timing for each layer based on their specific requirements. This segmentation allows optimized data capture performance for each layer while maintaining manageable control complexity through systematic management of individual layer parameters.

The patent applies local quality by assigning different charge collection time periods to different pixel layers based on their specific characteristics and requirements. Rather than using a uniform time period across all layers, each layer can have optimized charge collection timing. This local optimization improves signal quality where needed while minimizing unnecessary time extension in other layers, thus resolving the contradiction between measurement precision and time loss.
