Abstract: An image sensor includes a pixel array and a readout circuit. The pixel array includes a first unit pixel region including first, second and third sub-pixel regions having a first color filter, sequentially disposed along a first row line, and sharing a first floating diffusion region, and a second unit pixel region including a first, second and third sub-pixel regions having a second color filter, sequentially disposed along a second row line, and sharing a second floating diffusion region.

Abstract: An image sensor including: a pixel array having a plurality of pixels connected to a plurality of row lines and a plurality of column lines; a plurality of ramp buffers configured to output a ramp voltage generated by a ramp voltage generator; a sampling circuit including a plurality of samplers, each of the plurality of samplers having a first input terminal for receiving the ramp voltage and a second input terminal connected to one of the plurality of column lines; and a switching circuit configured to connect the first input terminals of the samplers to each other or disconnect the first input terminals of the samplers from each other.

Abstract: A correlated double sampling (CDS) circuit may include a sampling circuit and a switching circuit. The CDS circuit may perform a CDS operation on a reset component of an input signal and an image component of the input signal based on a ramp signal, and the CDS circuit may generate an output signal. The switching circuit may include an auto-zero switch that connects a first input terminal receiving the input signal to an output node in response to an auto-zero control signal during an auto-zero interval. The switching circuit may connect a first terminal of the auto-zero switch to a reference voltage in order to cutoff a leakage current flowing to the auto-zero switch in response to a first boosting control signal during a first comparison interval and a second comparison interval. The output signal may be provided at the output node.

Abstract: A portable terminal is provided. The portable terminal includes a display panel, a case member provided to surround at least both sides of the display panel, and a speaker hole formed in the case member and opened to at least one side of the display panel. The portable terminal includes the speaker hole in at least a side of the display panel by changing only a structure of the case member, such that the volume and quality of sound output from the speaker device can be fully delivered to a user who uses the terminal while viewing the display panel.

Abstract: A mobile terminal is provided in which gaps between keys provided in a second main body change as a first main body moves. The mobile terminal includes a first main body; a second main body having a plurality of keys; and a hinge connecting the first main body and the second main body, wherein when the first main body opens from the second main body, the second main body extends and gaps between the plurality of keys are widened, and when the first main body closes on the second main body, the second main body retracts and the gaps between the plurality of keys are narrowed. Therefore, when the mobile terminal is opened, gaps between keys provided in the mobile terminal are widened and thus a user can more conveniently use the keys provided in the mobile terminal.
