Abstract: Provided is an image sensor. The image sensor includes a pixel array including pixels arranged along a first direction and a second direction, and partitioned into blocks, a converter configured to convert image signals outputted from the pixels into digital signals based on an image, and an image signal processor configured to add amplitudes of the digital signals belonging to each of the blocks to determine edge blocks among the blocks, compare the amplitudes of the digital signals to determine directions in which direction lines of the edge blocks are directed, and connect the direction lines to extract an edge of the image.

Abstract: Provided is an operating method of a wearable device, the method including setting a threshold voltage when there is not a physical contact of an outsider, measuring an envelope voltage while performing a data communication, determining whether to be the physical contact with the outsider by comparing the threshold voltage with the envelope voltage, and stopping the data communication, when there is the physical contact with the outsider.

Abstract: Provided is a network-on-chip (NoC). The NoC includes a plurality of routers configured to receive power through each corresponding power gating switch, and a controller configured to control a power gating switch of each of the plurality of routers based on temperature information provided from each of the plurality of routers and control a driving clock of the plurality of routers. The controller controls the power gating switch to turn off at least one first router by referring to the temperature information and over-scale a clock frequency of at least one turned-on second router.
