  • Patent number: 11785355
    Abstract: An image processing device includes an image sensor including a pixel array that includes a first pixel group, and a correlated double sampling circuit. The first pixel group includes a first plurality of normal pixels, a second plurality of normal pixels, and at least one first phase detection pixel. The correlated double sampling circuit is configured to generate first video data, based on charges of the first plurality of normal pixels, generate second video data, based on charges of the second plurality of normal pixels, and generate first phase detection data, based on an output of the at least one first phase detection pixel. The image processing device further includes an image signal processor configured to apply a first weight to the generated first video data, and apply a second weight to the generated second video data.

  • Patent number: 9257462
    Abstract: In one embodiment, the image sensor includes a first photodiode configured to convert an optical signal into a photocharge, a sensing node configured to store the photocharge of the first photodiode, and a circuit configured to selectively output an electrical signal corresponding to the photocharge at the sensing node on an output line. The circuit is connected to at least a first conductive contact, and the output line is disposed between the sensing node and the first conductive contact.

  • Patent number: 8885065
    Abstract: A light leakage compensating unit image sensor in a back side illumination method includes a photodiode and a storage diode, in which light input to a back side of the unit image sensor is received only by an area forming an electrode of the photodiode, and an area for forming another electrode of the photodiode and an area for forming two electrodes of the storage diode are separated from each other by a well, thereby compensating light leakage.

  • Patent number: 8513036
    Abstract: A photonic quantum ring (PQR) laser includes an active layer having a multi-quantum-well (MQW) structure and etched lateral face. The active layer is formed to be sandwiched between p-GaN and n-GaN layers epitaxially grown on a reflector disposed over a support substrate. A coating layer is formed over an outside of the lateral faces of the active layer, and upper electrode is electrically connected to an upper portion of the n-GaN layer, and a distributed Bragg reflector (DBR) is formed over the n-GaN layer and the upper electrode. Accordingly, the PQR laser is capable of oscillating a power-saving vertically dominant 3D multi-mode laser suitable for a low power display device, prevent the light speckle phenomenon, and generate focus-adjusted 3D soft light.
