CPC Class H04N

A system and method tracks touches in a healthcare environment in order to analyze paths of transmission and contamination for the purpose of eliminating and containing transmission of colonizing, drug-resistant pathogens. Touches are identified and tracked with the use of recording devices. Each touch is logged and a touch graph is generated to identify transmission paths.

An image sensor having a pixel part generating a signal in accordance with a light, a signal processing part performing signal processing on the signal read from the pixel part, and a power supply part connected to the signal processing part via a first wiring, and supplying a power supply to the signal processing part, and a storage package storing the image sensor, and having a second wiring configuring a parallel circuit by being connected to the first wiring. Accordingly, it is possible to solve a problem such that a wiring resistance is increased when a power supply circuit is configured inside of a solid state image sensor.

An image sensor is provided to include image pixels and phase difference detection pixels. The image pixels may include image photodiodes formed in a substrate; color filters formed over the substrate and vertically overlapping with the image photodiodes; and image micro lenses over the color filters. The phase difference detection pixels may include phase difference detection photodiodes formed in the substrate; transmitting layers formed over the substrate and vertically overlapping with the phase difference detection photodiodes; guide patterns formed between the substrate and the transmitting layers; and phase difference detection micro lenses over the transmitting layers. The transmitting layers may have a refractive index lower than the color filters and the phase difference detection micro lenses.
