BSI-CMOS
Comparison of simplified back-illuminated and front-illuminated pixel cross-sections A back-illuminated (BI) sensor, also known as back-side illumination (BSI) sensor, is a type of digital image sensor that uses a novel arrangement of the imaging elements to increase the amount of light captured and thereby improve low-light performance. The technique was used for some time in specialized roles like low-light security cameras and astronomy sensors, but was complex to build and required further refinement to become widely used. Sony was the first to reduce these problems and their costs sufficiently to introduce a 5-megapixel 1.75 μm BI CMOS sensor at general consumer prices in 2009.''Sony'', 2009 BI sensors from OmniVision Technologies have since been used in consumer electronics from other manufacturers as in the HTC EVO 4G Android smartphone, and as a major selling point for the camera in Apple's iPhone 4.''Apple'', 2010 Description A traditional, front-illuminated dig ...

CMOS
Complementary metal–oxide–semiconductor (CMOS, pronounced "sea-moss ", , ) is a type of MOSFET, metal–oxide–semiconductor field-effect transistor (MOSFET) semiconductor device fabrication, fabrication process that uses complementary and symmetrical pairs of p-type semiconductor, p-type and n-type semiconductor, n-type MOSFETs for logic functions. CMOS technology is used for constructing integrated circuit (IC) chips, including microprocessors, microcontrollers, memory chips (including Nonvolatile BIOS memory, CMOS BIOS), and other digital logic circuits. CMOS technology is also used for analog circuits such as image sensors (CMOS sensors), data conversion, data converters, RF circuits (RF CMOS), and highly integrated transceivers for many types of communication. In 1948, Bardeen and Brattain patented an insulated-gate transistor (IGFET) with an inversion layer. Bardeen's concept forms the basis of CMOS technology today. The CMOS process was presented by Fairchild Semico ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

After Ibuka's retirement in the 1970s, Morita served as chairman until 1994, overseeing Sony's rise as a global brand recognized for innovation in consumer electronics. Landmark products included the Trinitron color television, the Walkma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exmor R
Exmor is a technology developed by Sony and implemented on some of their CMOS image sensors. It performs on-chip analog/digital signal conversion and two-step noise reduction in parallel on each column of the CMOS sensor. Sensors from the Exmor family have become widely available in consumer technology. History In October 2015, Sony Semiconductor Solutions was established as a wholly owned group company to reinforce the CMOS image sensor business and integrate the semiconductor-related business operations of Sony Group. Following the incorporation, all the Exmor sensors are designed and manufactured by the company. On 14 May 2020, the Intelligent Vision Sensor was announced with an introduction that reads: "the first image sensor in the world to be equipped with AI processing functionality". The new sensor distinguishes itself from the previous Exmor RS sensors by an AI processor and a memory storing the AI models, included in a stacked logic layer for the real-time im ...

USB-C
USB-C, or USB Type-C, is a 24-pin reversible Electrical connector, connector (not a Communication protocol, protocol) that supersedes previous USB hardware#Connectors, USB connectors (also supersedes Mini DisplayPort and Lightning (connector), Lightning connectors) that can transfer data, e.g. audio/video data, to connect to monitors, external drives, mobile phones, keyboards/mouses, and many more peripheral devices; sometimes indirectly via hubs/docking stations. It also exchanges electricity, in general to power peripheral devices. It is used not only by USB technology, but also by other data transfer protocols, including Thunderbolt (interface), Thunderbolt, PCIe, HDMI, DisplayPort, and others. It is Extensibility, extensible to support future protocols. The design for the USB-C connector was initially developed in 2012 by Intel, HP Inc., Microsoft, and the USB Implementers Forum.

Secure Digital
Secure Digital (SD) is a proprietary, non-volatile, flash memory card format developed by the SD Association (SDA). Owing to their compact size, SD cards have been widely adopted in a variety of portable consumer electronics, including digital cameras, camcorders, video game consoles, mobile phones, action cameras, and camera drones. The SD format was introduced in August 1999 by SanDisk, Panasonic (then known as Matsushita), and Kioxia (then part of Toshiba). It was designed as a successor to the MultiMediaCard (MMC) format, introducing several improvements aimed at enhancing usability, durability, and performance, which contributed to its rapid emergence as an industry standard. To manage the licensing and intellectual property rights related to the format, the three companies established SD-3C, LLC. In January 2000, they also founded the SDA, a non-profit organization dedicated to developing and promoting SD card standards. As of 2023, the SDA includes approximatel ...

Autofocus
An autofocus (AF) optical system uses a sensor, a control system and a motor to focus on an automatically or manually selected point or area. An electronic rangefinder has a display instead of the motor; the adjustment of the optical system has to be done manually until indication. Autofocus methods are distinguished as active, passive or hybrid types. Autofocus systems rely on one or more sensors to determine correct focus. Some AF systems rely on a single sensor, while others use an array of sensors. Most modern SLR cameras use through-the-lens optical sensors, with a separate sensor array providing light metering, although the latter can be programmed to prioritize its metering to the same area as one or more of the AF sensors. Through-the-lens optical autofocusing is usually speedier and more precise than manual focus with an ordinary viewfinder, although more precise manual focus can be achieved with special accessories such as focusing magnifiers. Autofocus accur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
