  • Patent number: 10587817
    Abstract: Disclosed is an electronic device including an image sensor including a lens, a pixel array configured to convert light collected through the lens into an electric signal and to output the electric signal, a readout circuit configured to convert electric signals sequentially received for each row of the pixel array into pixel data and to output the pixel data, a memory, and a controller configured to control the pixel array, the readout circuit and the memory, and a processor electrically connected to the image sensor. The controller is configured to generate a frame by integrating the pixel data sequentially received from the readout circuit, generate a profile regarding flickering of the collected light using the generated frame and another frame generated prior to the generated frame, and store the generated profile in the memory, obtain a profile set including profiles corresponding to a plurality of frames from the memory, and transfer the generated frame and the obtained profile set to the processor.

  • Patent number: 9099372
    Abstract: The inventive concept relates to a CMOS image sensor and an operating method of the CMOS image sensor. The operating method according to an embodiment of the inventive concept includes generating photoelectrons at a photo sensor element during a first time; generating photoelectrons at the photo sensor element during a second time shorter than the first time; and sensing the photoelectrons generated at the photo sensor element. A gate voltage of a transfer transistor connected to the photo sensor element is set differently at the first time and the second time. With an embodiment of the inventive concept, a dynamic range of the CMOS image sensor increases.
