WEEK+8

Digital Imaging uses an**: electronic image sensor to record the image as data**
 * Week 8: Digital Media**

There are two types of sensors: **CCD(charge coupled device) and CMOS(complementary metal-oxide semiconductor)**

A single element, point or dot that contains color: **pixel** DV: Digital Video; DVB; Digital Video Broadcast; HDTV: High-definition television European TV uses **PAL format**, which runs at 24 or 25 frames per second. Movies (as shown in theaters) also commonly used these frame rates. US TV uses the **NTSC format**, which runs at 29.997 frames per second (effectively 30). Equivalent frame rate as seen by the human eye is similar, and each has pros and cons. 240p: VHS quality 480p: Standard definition TV (actually 480i) 720p: High definition TV 1080p: High definition TV (as 1080i), Blu-Ray Dots per inch (DPI) and pixels per inch (PPI)
 * fps ** = frames per second
 * Interlaced: ** Displays alternating lines of video at 60 fps. The “I” refers to interlaced.
 * Progressive: ** Displays full frames of video at 30 fps. The “p” refers to progressive.

How are pixels and resolution related? **the number of pixels drawn across and down are how resolution is measured**

What is bit depth? **the number of bits of information each pixel can understand**
