    Abstract: An image sensor includes an active pixel array, at least one dummy reset array, a dummy read array, and an image processor. The image processor sequentially resets respective rows of pixels included in the at least one dummy reset array in a period in which pixels of the active pixel array do not perform a reset operation, and sequentially reads respective rows of pixels included in the dummy read array in a period in which the pixels of the active pixel array do not perform a read operation.

    Abstract: An electronic device for iris recognition and an operating method thereof are provided. The electronic device includes a housing including a first surface, a display exposed through a first region of the first surface, a light emitting unit comprising light emitting circuitry disposed in a second region of the first surface, an image device comprising image acquiring circuitry disposed in a third region of the first surface, at least one processor disposed within the housing and electrically connected with the display, the light emitting unit and the image device, and a memory disposed within the housing and electrically connected with the at least one processor. The memory stores instructions that, when executed by the processor, cause the electronic device to store a reference template based on a first iris image which has been recognized using the light emitting unit and the image device, to authenticate a second iris image which has been recognized using the light emitting unit and the image device, using the stored reference template, and to store a template of the second iris image succeeded in authentication, as an additional template.
