Pixel array is disposed in first semiconductor die and is partitioned into pixel sub-arrays. Each pixel sub-array is arranged into pixel groups, and each pixel group is arranged into pixel cell array. Readout circuits disposed in second semiconductor die acquire image data of first and second frame. Each pixel sub-array is coupled to a corresponding readout circuit through a corresponding one of a plurality of conductors. ADC circuits convert image data from first and second frames to first and second ADC outputs. Function logic on the second semiconductor die adding first and second ADC outputs to generate a final ADC output. Other embodiments are also described."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system to implement a stacked chip high dynamic range image sensor","description":"Method of implementing stacked chip HDR algorithm in image sensor starts with pixel array capturing first frame with first exposure time and second frame with a second exposure time that is longer or ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9819889","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
