Abstract: An image sensor device, including a pixel array comprising a plurality of optical black pixels and a plurality of active pixels, wherein the plurality of optical black pixels are configured to be read out during a first time period to generate first data voltages and the plurality of active pixels are configured to be read out during a second time period after the first time period to generate second data voltages; an analog-to-digital converter configured to output first pixel codes based on the first data voltages, and to output second pixel codes based on the second data voltages; an image signal processor configured to output image frame data based on the first pixel codes and the second pixel codes; and a dummy code generator configured to provide dummy codes to the image signal processor during a third time period between a first time point and a second time point, wherein the first time point is before the first time period.
