摘要： An interface circuit including: a first transmission circuit outputting a first signal to a transmission line via first transfer pads; and a second transmission circuit outputting a second signal to the transmission line via second transfer pads, the first transmission circuit includes a first termination resistor block including a switch and a first termination resistor connected between the first transfer pads, the second transmission circuit includes a second termination resistor block including a switch and a second termination resistor connected between the second transfer pads, and when the first transmission circuit outputs the first signal, the second termination resistor block detects the first signal, and when the first transmission circuit is in a low-power operation mode, the second termination resistor block disconnects the second termination resistor, and when the first transmission circuit is in a high-speed data transfer mode, the second termination resistor block connects the second termination resistor.

摘要： An image sensor including an image signal processor and an operating method of the image sensor are provided. An image sensor may include a pixel array configured to convert a received optical signal into electrical signals, a readout circuit configured to analog-digital convert the electrical signals to generate image data, and an image signal processor configured to perform one-dimensional filtering in each of a first direction and a second direction on the image data to remove noise of the image data, the second direction being different than the first direction.
