Abstract: Disclosed are an image sensor having a light-emitting diode (LED) flicker mitigation function and an image processing system including the image sensor. The image processing system includes an image sensor including a plurality of pixels, the plurality of pixels configured to respectively generate pixel signals corresponding to photocharges, and configured to perform analog-to-digital conversion (ADC) on the pixel signals to generate digital pixel signals; and an image signal processor configured to process the digital pixel signals to generate image data. The image sensor operates in a first operating mode in a situation in which a light-emitting diode (LED) light is provided, and operates in a second operating mode in a general situation in which the LED light is not provided.

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.

Abstract: A method of operating an image sensing device includes applying control voltages to a pixel array in accordance with a test mode and performing an analog-to-digital conversion of a column line voltage to obtain one or more digital codes. The one or more digital codes are evaluated to detect an operating error associated with the column line and/or corresponding analog to digital converter. In response to an operating error, pixel values may be replaced or averaged with nearby pixel outputs not affected by the operating error.
