  • Patent number: 11924565
    Abstract: An image sensor includes a pixel array, a row driver, a detector, an analog-to-digital converter and a controller. The pixel array includes a pixel area including a pixel and a dummy area including a monitoring circuit. The dummy area is disposed on a same substrate as the pixel area. The dummy area is disposed adjacent to the pixel area. The row driver is configured to output a driving signal to the pixel and the monitoring circuit. The detector is configured to receive a monitoring signal from the monitoring circuit. The analog-to-digital converter is configured to receive an analog signal corresponding to an incident light from the pixel and to convert the analog signal to a digital signal. The controller is configured to control the row driver and the analog-to-digital converter.

  • Patent number: 10129492
    Abstract: An image sensor capable of implementing a global shutter mode and a rolling shutter mode is provided. The image sensor includes a row driver, a pixel array, an analog-to-digital converter, and an output compensating circuit. The row driver performs decoding for a reset operation, a transfer operation and a read operation, and generates control signals. The pixel array, in a rolling shutter mode, performs the transfer operation on a second row group while the read operation for a first row group is performed, and receives an optical signal, converts the optical signal to electrical signal, and outputs the electrical signal as an image signal in response to the control signals.
