Abstract: An image sensor includes a first semiconductor chip which extends in first and second directions that intersect each other, and having a pixel part including a plurality of pixel regions; and a second semiconductor chip including a circuit part electrically connected to the pixel part, on the first semiconductor chip. The pixel part includes a photodiode, a floating diffusion node which accumulates photocharges generated by the photodiode, and a first source follower which amplifies and outputs a signal corresponding to a change in potential of the floating diffusion node. The circuit part includes a first pre-charge selection transistor connected between a first node and a second node, a second pre-charge selection transistor connected to the first pre-charge selection transistor, and a pre-charge transistor which pre-charges the second node connected to the first source follower. The plurality of pixel regions share the pre-charge transistor.

Abstract: A control method of an inputter comprises an operation in which at least one of the inputter and an electronic apparatus connected to the inputter acquires reference data, an operation in which a manipulation detector of the inputter outputs a manipulation detection signal, an operation in which a light source of the inputter irradiates a first light, an operation in which a light detector detects a first reflected light that is incident to the light detector among the irradiated first light, and an operation in which at least one of the inputter and the electronic apparatus compares a detection result of the first reflected light and the reference data, and identifies whether the manipulation detector outputting the manipulation signal malfunctions, based on a comparison result.
