Pixel Camera
Pixel Camera is a camera phone application developed by Google for the Android operating system on Google Pixel devices. Development with zoom lenses for the application began in 2011 at the Google X research incubator led by Marc Levoy, which was developing image fusion technology for Google Glass. It was publicly released for Android 4.4+ on the Google Play on April 16, 2014. The app was initially released as Google Camera and supported on all devices running Android 4.4 KitKat and higher. However, in October 2023, coinciding with the release of the Pixel 8 series, it was renamed to Pixel Camera and became officially supported only on Google Pixel devices. Features Google Camera contains a number of features that can be activated either in the Settings page or on the row of icons at the top of the app. Pixel Visual/Neural Core Starting with Pixel devices, the camera app has been aided with hardware accelerators, a hidden image processing chip, to perform its image processi ...

Pixel 2
The Pixel 2 and Pixel 2 XL are a pair of Android smartphones designed, developed, and marketed by Google as part of the Google Pixel product line. They collectively serve as the successors to the Pixel and Pixel XL. They were officially announced on October 4, 2017 at the Made by Google event and released in the United States on October 19. On October 9, 2018, they were succeeded by the Pixel 3 and Pixel 3 XL. History In early March 2017, Google's Rick Osterloh confirmed that they would bring a "next-gen" Pixel smartphone later that year. He stated it would "stay premium" and that there would be no "cheap Pixel". Google originally intended to use HTC to manufacture both their 2017 flagships, but later shifted to LG to manufacture the bigger Pixel 2 XL. The unreleased device that was supposed to be the Pixel 2 XL under the codename "Muskie", was later re-developed by HTC into the HTC U11+. The Google Pixel 2 and Pixel 2 XL were carried in the United States by Verizon and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nexus 5
Nexus 5 (code-named Hammerhead) is an Android (operating system), Android smartphone sold by Google and manufactured by LG Electronics. It is the fifth generation of the Google Nexus, Nexus series, succeeding the Nexus 4. It was unveiled on October 31, 2013 and served as the launch device for Android KitKat, Android 4.4 "KitKat", which introduced a refreshed interface, performance improvements, greater Google Now integration, and other changes. Much of the hardware is similar to the LG G2 which was also made by LG and released earlier that year. The Nexus 5 received mostly positive reviews, praising the device's balance of overall performance and cost in comparison to other "flagship" phones, along with the quality of its display and some of the changes introduced by Android 4.4. The Nexus 5 was followed by the Nexus 6 in October 2014, although the Nexus 6 is a higher-end phablet and not a direct successor, with the Nexus 5 and Nexus 6 sold alongside each other for sev ...

Motion Blur
Motion blur is the apparent streaking of moving objects in a photograph or a sequence of frames, such as a film or animation. It results when the image being recorded changes during the recording of a single exposure, due to rapid movement or long exposure. Usages / Effects of motion blur Photography When a camera creates an image, that image does not represent a single instant of time. Because of technological constraints or artistic requirements, the image may represent the scene over a period of time. Most often this exposure time is brief enough that the image captured by the camera appears to capture an instantaneous moment, but this is not always so, and a fast moving object or a longer exposure time may result in blurring artifacts which make this apparent. As objects in a scene move, an image of that scene must represent an integration of all positions of those objects, as well as the camera's viewpoint, over the period of exposure determined by the shutter speed. ...

Exposure (photography)
In photography, exposure is the amount of light per unit of measurement, unit area (the image plane's illuminance times the exposure time) reaching a frame of photographic film or the surface of an electronic image sensor, as determined by shutter speed, lens F-number, and scene luminance. Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance in a specified region. An "exposure" is a single shutter cycle. For example, a long-exposure photography, long exposure refers to a single, long shutter cycle to gather enough dim light, whereas a multiple exposure involves a series of shutter cycles, effectively layering a series of photographs in one image. The accumulated ''photometric exposure'' (''H''v) is the same so long as the total exposure time is the same. Definitions Radiant exposure Radiant exposure of a ''surface'', denoted ''H''e ("e" for "energetic", to avoid confusion with Photometry (optics), photometric quantities) and m ...

Shot Noise
Shot noise or Poisson noise is a type of noise which can be modeled by a Poisson process. In electronics shot noise originates from the discrete nature of electric charge. Shot noise also occurs in photon counting in optical devices, where shot noise is associated with the particle nature of light. Origin In a statistical experiment such as tossing a fair coin and counting the occurrences of heads and tails, the numbers of heads and tails after many throws will differ by only a tiny percentage, while after only a few throws outcomes with a significant excess of heads over tails or vice versa are common; if an experiment with a few throws is repeated over and over, the outcomes will fluctuate a lot. From the law of large numbers, one can show that the relative fluctuations reduce as the reciprocal square root of the number of throws, a result valid for all statistical fluctuations, including shot noise. Shot noise exists because phenomena such as light and electric current co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lucky Imaging
Lucky imaging (also called lucky exposures) is one form of speckle imaging used for astrophotography. Speckle imaging techniques use a high-speed camera with exposure times short enough (100 ms or less) so that the changes in the Earth's atmosphere during the exposure are minimal. With lucky imaging, those optimum exposures least affected by the atmosphere (typically around 10%) are chosen and combined into a single image by shifting and adding the short exposures, yielding much higher angular resolution than would be possible with a single, longer exposure, which includes all the frames. Explanation Images taken with ground-based telescopes are subject to the blurring effect of atmospheric turbulence (seen to the eye as the stars twinkling). Many astronomical imaging programs require higher resolution than is possible without some correction of the images. Lucky imaging is one of several methods used to remove atmospheric blurring. Used at a 1% selection or less, lucky ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computational Photography
Computational photography refers to digital image capture and processing techniques that use digital computation instead of optical processes. Computational photography can improve the capabilities of a camera, or introduce features that were not possible at all with film based photography, or reduce the cost or size of camera elements. Examples of computational photography include in-camera computation of digital panoramas, high-dynamic-range images, and light field cameras. Light field cameras use novel optical elements to capture three dimensional scene information which can then be used to produce 3D images, enhanced depth-of-field, and selective de-focusing (or "post focus"). Enhanced depth-of-field reduces the need for mechanical focusing systems. All of these features use computational imaging techniques. The definition of computational photography has evolved to cover a number of subject areas in computer graphics, computer vision, and applied optics. These areas are ...

High Dynamic Range
High dynamic range (HDR) is a dynamic range higher than usual, synonyms are wide dynamic range, extended dynamic range, expanded dynamic range. The term is often used in discussing the dynamic range of various signals such as images, videos, audio or radio. It may apply to the means of recording, processing, and reproducing such signals including analog and digitized signals. The term is also the name of some of the technologies or techniques allowing to achieve high dynamic range images, videos, or audio. Imaging In this context, the term ''high dynamic range'' means there is a lot of variation in light levels within a scene or an image. The '' dynamic range'' refers to the range of luminosity between the brightest area and the darkest area of that scene or image. (HDRI) refers to the set of imaging technologies and techniques that allow to increase the dynamic range of images or videos. It covers the acquisition, creation, storage, distribution and display of images a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Google APIs
Google APIs are application programming interfaces ( APIs) developed by Google which allow communication with Google Services and their integration to other services. Examples of these include Search, Gmail, Translate or Google Maps. Third-party apps can use these APIs to take advantage of or extend the functionality of the existing services. The APIs provide functionality like analytics, machine learning as a service (the Prediction API) or access to user data (when permission to read the data is given). Another important example is an embedded Google map on a website, which can be achieved using the Static Maps API, Places API or Google Earth API. Authentication and authorization Usage of all of the APIs requires authentication and authorization using the Oauth 2.0 protocol. Oauth 2.0 is a simple protocol. To start, it is necessary to obtain credentials from the Developers Console. Then the client app can request an access Token from the Google Authorization Server, an ...
