Video quality. Video quality is a characteristic of a video passed through a video transmission or processing system that describes perceived video degradation (typically compared to the original video). Video processing systems may introduce some amount of distortion or artifacts in the video signal that negatively impact the user's perception ...
The DXOMARK Sensor Score measures several important image quality metrics of the RAW image [8] captured by the camera 's sensor. [9] The overall score is a confidential combination of three sub-scores: [9] [10] Colour depth, measured in bits, called a Portrait score; Dynamic range, measured in stops of dynamic range, called a Landscape score;
Test card. SMPTE color bars: common NTSC test pattern. PM5544: common PAL test pattern. EBU colour bars (4:3) A test card, also known as a test pattern or start-up/closedown test, is a television test signal, typically broadcast at times when the transmitter is active but no program is being broadcast (often at sign-on and sign-off ). [1]
Gamma correction is a type of power law function whose exponent is the Greek letter gamma ( γ ). It should not be confused with the mathematical Gamma function. The lower case gamma, γ, is a parameter of the former; the upper case letter, Γ, is the name of (and symbol used for) the latter (as in Γ ( x )).
Indian-head test pattern. The Indian-head test pattern is a test card that gained widespread adoption during the black-and-white television broadcasting era as an aid in the calibration of television equipment. It features a drawing of a Native American wearing a headdress surrounded by numerous graphic elements designed to test different ...
A high-speed camera is a device capable of capturing moving images with exposures of less than 1 1 000 second or frame rates in excess of 250 frames per second. [1] It is used for recording fast-moving objects as photographic images onto a storage medium. After recording, the images stored on the medium can be played back in slow motion.
Interlaced video (also known as interlaced scan) is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth. The interlaced signal contains two fields of a video frame captured consecutively. This enhances motion perception to the viewer, and reduces flicker by taking advantage of the ...
Frame rate, most commonly expressed in frames per second or FPS, is typically the frequency (rate) at which consecutive images ( frames) are captured or displayed. This definition applies to film and video cameras, computer animation, and motion capture systems. In these contexts, frame rate may be used interchangeably with frame frequency and ...
