Image Stabilization
Image stabilization (IS) is a family of techniques that reduce motion blur, blurring associated with the motion of a camera or other imaging device during exposure (photography), exposure. Generally, it compensates for panning (camera), pan and tilt (camera), tilt (angular movement, equivalent to aircraft principal axes, yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation about the optical axis (aircraft principal axes, roll). It is mainly used in high-end image-stabilized binoculars, digital camera, still and video camera, video cameras, astronomical telescopes, and also smartphones. With still cameras, camera shake is a particular problem at slow shutter speeds or with long focal length lenses (telephoto lens, telephoto or zoom lens, zoom). With video cameras, camera shake causes visible frame-to-frame jitter (optics), jitter in the recorded video. In astronomy, the problem of lens shake is added to Astronomical seeing, ...

As a self-described "camera fanatic" owning over 1,000 models, Jannard started the company with the intent to deliver a (relatively) affordable 4K resolution, 4K digital cinema camera. Jannard dates the idea to a time when he bought a Sony HDR-FX1 video camera and learned that the files had to be converted with software from Lumiere HD and were not viewable on Mac OS. Lumiere HD's owner Frederic Lumiere collaborated with Jannard on d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3D Lookup Table
In the film and graphics industries, 3D lookup tables (3D LUTs) are used for color grading and for mapping one color space to another. They are commonly used to calculate preview colors for a monitor or digital projector of how an image will be reproduced on another display device, typically the final digitally projected image or release print of a movie. A 3D LUT is a 3D lattice of output RGB color values that can be indexed by sets of input RGB colour values. Each axis of the lattice represents one of the three input color components and the input color thus defines a point inside the lattice. Since the point may not be on a lattice point, the lattice values must be interpolated; most products use trilinear interpolation.Selan, Jeremy (2004). "Using Lookup Tables to Accelerate Color Transformations" ''GPU Gems 2'', Chapter 24. https://developer.nvidia.com/gpugems/GPUGems2/gpugems2_chapter24.html 3D LUTs are used extensively in the movie production chain, as part of the digit ...

High Efficiency Video Coding
High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a video compression standard designed as part of the MPEG-H project as a successor to the widely used Advanced Video Coding (AVC, H.264, or MPEG-4 Part 10). In comparison to AVC, HEVC offers from 25% to 50% better data compression at the same level of video quality, or substantially improved video quality at the same bit rate. It supports resolutions up to 8192×4320, including 8K UHD, and unlike the primarily 8-bit AVC, HEVC's higher fidelity Main 10 profile has been incorporated into nearly all supporting hardware. While AVC uses the integer discrete cosine transform (DCT) with 4×4 and 8×8 block sizes, HEVC uses both integer DCT and discrete sine transform (DST) with varied block sizes between 4×4 and 32×32. The High Efficiency Image Format (HEIF) is based on HEVC. Concept In most ways, HEVC is an extension of the concepts in H.264/MPEG-4 AVC. Both work by comparing different parts of a fra ...

Hybrid Log–gamma
The hybrid log–gamma (HLG) transfer function is a transfer function jointly developed by the BBC and NHK for high dynamic range (HDR) display. It is backward compatible with the transfer function of SDR (the gamma curve). It was approved as ARIB STD-B67 by the Association of Radio Industries and Businesses (ARIB). It is also defined in ATSC 3.0, Digital Video Broadcasting (DVB) UHD-1 Phase 2, and International Telecommunication Union (ITU) Rec. 2100. HLG is an HDR format that uses the HLG transfer function, BT.2020 color primaries and a bitdepth of 10-bit. HLG was designed to be backward compatible with SDR UHDTV. However, HLG is not intended to be fully backward compatible with traditional SDR displays that cannot interpret BT.2020 colorimetry. Both HLG transfer function and the HLG format are royalty-free. The backward compatibility allows them to be used with existing transmission standards when the receiver is compatible with the BT.2020 colour container, reducing ...

Lens Adapter
In photography and videography, a lens adapter is a device that enables the use of camera and lens combinations from otherwise incompatible systems. The most simple lens adapter designs, passive lens adapters provide a secure physical connection between the camera and the lens. Some passive adapters may include a mechanism for manual Diaphragm (optics), iris control. So called, active lens adapters will include electronic connections, enabling communication between the lens and the camera. Some lens adapters include a special optical element called a telecompressor, focal reducer, or more recently a "speed booster", a Generic trademark, genericised trademark that refers to the Metabones Speed Booster line of lens adapters. This type of adapter is designed to reduce focal length, increase lens speed, and in some instances improve MTF performance. Another innovator in the field is KIPON, a German/Chinese co-operation between Kipon and IB/E Optics. Another branch of lens adapters ...

Nikon F-mount
The Nikon F-mount is a type of interchangeable lens mount developed by Nikon for its 35mm format single-lens reflex cameras. The F-mount was first introduced on the Nikon F camera in 1959, and features a three-lug bayonet mount with a 44mm throat and a Flange focal distance, flange to focal plane distance of 46.5mm. The company continues, with the 2020 D6 model, to use variations of the same lens mount specification for its film and digital single-lens reflex camera, digital SLR cameras. The Nikon F-mount successor is the Nikon Z-mount. History The Nikon F-mount is one of only two SLR lens mounts (the other being the Pentax K-mount) which were not abandoned by their associated manufacturer upon the introduction of autofocus, but rather extended to meet new requirements related to light meter, metering, autofocus, and aperture control. The large variety of F-mount compatible lenses makes it the largest system of interchangeable flange-mount photographic lenses in history. Over ...
