In one example, charge is collected at a photodetector of a photodetector circuit for a first duration for a first mini-exposure. The photodetector charge is transferred to a charge collection node of the photodetector circuit. A portion of the transferred charge is spilled from the charge collection node. Charge is collected at the photodetector for a second duration for a second mini-exposure. The second mini-exposure photodetector charge is transferred to the charge collection node after spilling the portion. The collected charge is read after transferring the second mini-exposure photodetector charge and the spilled portion of the charge is estimated and the spilled portion is added to the collected charge reading to obtain a total charge value for the combined exposures."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image sensor operation for shutter modulation and high dynamic range","description":"An image sensor is operated for shutter modulation and high dynamic range, suitable for use with a local lamp.
