The image pickup device and the electronic device include a sample and hold unit configured to perform sampling and holding of a pixel signal, an analog digital (AD) conversion unit configured to perform AD conversion of the pixel signal that includes a digit after a decimal point, a digital gain processing unit configured to apply a predetermined gain to a digital signal from the AD conversion unit, and a gain setting unit configured to set an analog gain of a column unit including the sample and hold unit and the AD conversion unit. The gain setting unit sets the analog gain in accordance with a measured dark current amount. The present technology can be applied, for example, to a CMOS image sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image pickup device and electronic device","description":"The present technology relates to an image pickup device and an electronic device that enables a reduction in influence exerted by a dark current.
