Abstract: [Object] To execute online calibration without using a light source. [Solution] An image sensor includes: a pixel array portion in which a plurality of pixels are disposed and which generates a pixel signal; a reference signal generation unit configured to generate a reference signal for calibration; an analog digital (AD) conversion unit configured to execute AD conversion on the pixel signal and the reference signal to generate pixel data and reference data; and a correction processing unit configured to correct the pixel data on a basis of the reference data. The present technology can be applied to, for example, an image sensor performing online calibration.

Abstract: The present disclosure relates to a solid-state imaging device, a solid-state imaging device operating method, an imaging apparatus, and an electronic apparatus that can realize an image at a low resolution with low power consumption without deteriorating imaging characteristics of all pixels. A floating interconnection line connecting FDs (floating diffusions) each set in a unit of shared pixels including at least one or more pixels, the FDs being provided in each column having a predetermined column number, and a switch changing over between connection and disconnection of the floating interconnection line to and from the FDs are provided. In addition, the switch changes over between the connection and the disconnection between the FDs and the floating interconnection line in response to a resolution that is a low resolution. The present disclosure can be applied to a solid-state imaging device.
