    摘要： The image sensor includes: a semiconductor substrate having a first conductivity type and including a first surface, a second surface opposite to the first surface, and a well region adjacent to the first surface. A first vertical transfer gate and a second vertical transfer gate are spaced apart from each other and extend in a thickness direction of the semiconductor substrate from the first surface to pass through at least a part of the well region. A photoelectric conversion region has a second conductivity type, which is different from the first conductivity type, is located in the semiconductor substrate between the well region and the second surface, and overlaps the first vertical transfer gate and the second vertical transfer gate in the thickness direction of the semiconductor substrate. A wiring structure is located on the first surface of the semiconductor substrate.

    摘要： A method and an apparatus for controlling a display in order to secure an appropriate viewing distance between a digital device and a user who is viewing the digital device is provided. Accordingly, the method determines whether an object exists within a hazardous viewing distance using a 3D camera function provided in the digital device. If it is determined that an object exists within the hazardous viewing distance, the digital device detects a face or eyes from 2D images photographed by the camera. Next, the direction of the face is determined on the basis of the detected results, and it is determined whether a user is viewing a display screen of the digital device based on the determination. If it is determined that a user is viewing a display screen of a digital device, the digital device generates a warning that the user is positioned within a hazardous viewing distance.

    摘要： A pixel array in a three-dimensional image sensor includes depth pixels and an ambient light cancellation (ALC) circuit. The depth pixels operate in response to photo control signals having different phases, and generate distance information of an object based on light reflected by the object. The ALC circuit removes an ambient light component from the reflected light, and is shared by the depth pixels. Each depth pixel includes a photoelectric conversion region, a floating diffusion region, a photo gate, and a drain gate. The photoelectric conversion region collects photo charges based on the reflected light. The floating diffusion region accumulates the photo charges. The photo gate is activated in response to one of the photo control signals. The photoelectric conversion region accumulates the photo charges when the photo gate is activated, and the photo charges in the photoelectric conversion region are released when the drain gate is activated.
