2. Video scaler - Wikipedia

   en.wikipedia.org/wiki/Video_scaler

   A video scaler is a system which converts video signals from one display resolution to another; typically, scalers are used to convert a signal from a lower resolution (such as 480p standard definition) to a higher resolution (such as 1080i high definition ), a process known as "upconversion" or "upscaling" (by contrast, converting from high to ...

3. Lines per inch - Wikipedia

   en.wikipedia.org/wiki/Lines_per_inch

   Lines per inch ( LPI) is a measurement of printing resolution. A line consists of halftones that is built up by physical ink dots made by the printer device to create different tones. Specifically LPI is a measure of how close together the lines in a halftone grid are. The quality of printer device or screen determines how high the LPI will be.

4. Frame rate - Wikipedia

   en.wikipedia.org/wiki/Frame_rate

   Frame rate up-conversion (FRC) is the process of increasing the temporal resolution of a video sequence by synthesizing one or more intermediate frames between two consecutive frames. A low frame rate causes aliasing, yields abrupt motion artifacts, and degrades the video quality. Consequently, the temporal resolution is an important factor ...

5. Sample-rate conversion - Wikipedia

   en.wikipedia.org/wiki/Sample-rate_conversion

   Sample-rate conversion. Sample-rate conversion, sampling-frequency conversion or resampling is the process of changing the sampling rate or sampling frequency of a discrete signal to obtain a new discrete representation of the underlying continuous signal. [1] Application areas include image scaling [2] and audio/visual systems, where different ...

6. Gigapixel image - Wikipedia

   en.wikipedia.org/wiki/Gigapixel_image

   A gigapixel image is a digital image bitmap composed of one billion (10 9) pixels (picture elements), 1000 times the information captured by a 1 megapixel digital camera. A square image of 31,623 pixels in width and height is one gigapixel. Current technology for creating such very high-resolution images usually involves either making digital ...

7. Dots per inch - Wikipedia

   en.wikipedia.org/wiki/Dots_per_inch

   Dots per inch. A close-up of the dots produced by an inkjet printer at draft quality. Actual size is approximately 1⁄4 by 1⁄4 inch (6 by 6 mm). Individual coloured droplets of ink are visible; this sample is about 150 DPI. Dots per inch ( DPI, or dpi [1]) is a measure of spatial printing, video or image scanner dot density, in particular ...

8. Video super-resolution - Wikipedia

   en.wikipedia.org/wiki/Video_super-resolution

   Video super-resolution ( VSR) is the process of generating high-resolution video frames from the given low-resolution video frames. Unlike single-image super-resolution (SISR), the main goal is not only to restore more fine details while saving coarse ones, but also to preserve motion consistency. There are many approaches for this task, but ...

9. List of common display resolutions - Wikipedia

   en.wikipedia.org/wiki/List_of_common_display...

   The resolution of 960H depends on whether the equipment is PAL or NTSC based: 960H represents 960 x 576 (PAL) or 960 x 480 (NTSC) pixels. [29] 960H represents an increase in pixels of some 30% over standard D1 resolution, which is 720 x 576 pixels (PAL), or 720 x 480 pixels (NTSC). The increased resolution over D1 comes as a result of a longer ...
