Pixel array includes visible pixels and black pixels (OPB). Scanning circuitry then selects OPB of first frame to be readout. OPB generate a dark signal when selected by scanning circuitry. Column readout circuitry included in readout circuitry then acquires the dark signal of first frame and processes the dark signal based on a ramp signal received from ramp generator included in readout circuitry to generate dark ADC output. Readout circuitry then determines a ramp timing offset based on the dark signal of first frame. The ramp timing offset is then applied to the second frame, which includes generating by the ramp generator the ramp signal for a second frame that includes the ramp timing offset. Other embodiments are described."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for reducing analog-to-digital conversion time for dark signals","description":"A method for reducing ADC time for dark signals starts with pixel array capturing image data of frames including first frame and second frame.
