Definition of Aspect Ratio

Aspect ratio is simply the ratio of an image’s width to its height. It is also know as display aspect ratio(DAR) or picture aspect ratio (PAR). If the ratio of an image is different than the ratio of your screen, you may not see the whole image. \begin{align*} Aspect\ Ratio [...]

Interlaced vs Progressive Scanning

Interlaced Scanning In Interlaced scanning alternating sets of lines are displayed. First even numbered lines are displayed and then odd numbered lines are displayed. Each even set of lines are displayed for 1/60th of a second and then the odd lines are displayed for 1/60th of a second in case [...]

What is Chroma Subsampling ?

Chroma subsampling is the process of encoding images by implementing less resolution for chroma information than for luma information. Human visual system is much more sensitive to variations in brightness (luminance or luma) than color (chrominance or chroma). A video system can be optimized by devoting more bandwidth to the [...]

BT.601 YUV to RGB Conversion | Color

Introduction YUV is a color encoding system used as part of a color image pipeline. It encodes a color image or video taking human perception into account, allowing reduced bandwidth for chrominance components. Y'UV model defines a color space in terms of one luma (Y') and two chrominance (UV) components. [...]

Color and Light | Color

Wavelength Wavelength of light determines the nature of the light. We can describe light as electromagnetic waves with color identified by its wavelength. A single photon of one color differs from a photon of another color only by its energy. Visible light is the range of wavelengths within the electromagnetic [...]
