The system includes an image sensor that creates image data from the electromagnetic pulses. The image sensor has a plurality of subsets of differing pixels, where each of the pixels comprises a transfer gate transistor. Each transfer gate transistor in one subset of pixels is electrically connected by a TX signal. The TX signal provides global operation of transfer gate transistor (TX) per subset of pixels. The system includes a memory comprising instructions for controlling the emitter so as to pulse for a plurality of exposures that correspond to the subsets of differing pixels and instructions that coordinate the electromagnetic pulses being emitted during a blanking portion of the image sensor frame period. The system includes a processor that combines a plurality of exposures to expand dynamic range."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wide dynamic range using monochromatic sensor","description":"A system for digital imaging in a light deficient environment includes an emitter for providing illumination with electromagnetic pulses.
