The time resolution used for movies is usually 24 to 48 frames per second (frames/s), whereas high-speed cameras may resolve 50 to 300 frames/s, or even more. The Heisenberg uncertainty principle describes the fundamental limit on the maximum spatial resolution of information about a particle's coordinates imposed by the measurement or ...
While typically referring to motion pictures, some digital camera vendors have used the term "4K photo" for still photographs, making it appear like an especially high resolution even though 3840×2160 pixels equal approximately 8.3 megapixels, which is not considered to be especially high for still photographs.

The previous record may have belonged to Jim Hellemn of Blue Ocean Art. In 1999, Hellemn created a 1.77 gigapixel underwater photocomposite image, which was designed to facilitate life-size reproduction of a 20 ft high by 70 ft wide section of Bloody Bay Wall, a vertical coral reef wall in the Cayman Islands.
Digital material is provided to widescreen TVs either in high-definition format, which is natively 16:9 (1.78:1), or as an anamorphically-compressed standard-definition picture. Typically, devices decoding Digital Standard-Definition pictures can be programmed to provide anamorphic widescreen formatting, for 16:9 sets, and formatting for 4:3 sets.
The term high definition once described a series of television systems first announced in 1933 [1] and launched starting in August 1936; [5] however, these systems were only high definition when compared to earlier systems that were based on mechanical systems with as few as 30 lines of resolution. The ongoing competition between companies and ...
The HD or 720p resolution of 1280 × 720 pixels stems from high-definition television (HDTV), where it originally used 50 or 60 frames per second. With its 16:9 aspect ratio, it is exactly 2 times the width and 1 + 1 / 2 times the height of 4:3 VGA ( 640 × 480 ), which shares its aspect ratio and 480 line count with NTSC .
High-Definition Multimedia Interface (HDMI), all-digital audio/video interface capable of transmitting uncompressed streams; High-definition television (HDTV), television signals and apparatus with higher resolution than their contemporary counterparts Ultra-high-definition television, a further step in television resolution, but not a successor.
High Efficiency Image File Format (HEIF) is a digital container format for storing individual digital images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text , audio and video.
