paints pixels on the screen with a pointing device such as mouse, stylus

Front 3

Bitmapped Graphics

Back 3

pictures show how the pixels are mapped on the screen

Front 4

Gray-Scale Graphics

Back 4

uses 8 bits per pixel; allows up to 256 shades of gray

Front 5

Colour Depth

Back 5

number of bits devoted to each pixel

Front 6

Resolution

Back 6

density of pixels; (DPI) Dots Per Inch

Front 7

Anti-aliasing

Back 7

smoothes out less than ideal resolutions

Front 8

Image Processing

Back 8

users manipulate photos with tools such as Adobe Photoshop

More powerful than traditional photo-retouching techniques

Can distort and combine photos

Can create fabricated images that show no evidence of tampering

Front 9

Digital Photo Management Software Programs

Back 9

simplify and automate common tasks associated with capturing, organising, editing, and sharing digital images

Apple Iphoto

Google Picasa

Front 10

Drawing Software

Back 10

stores a picture as a collection of lines and shapes (object-oriented or vector graphics)

Front 11

PDF

Back 11

(portable document format)

file format developed by Adobe

enables digital documents to be exchanged between programs independent of application software, hardware, or operating system

can contain texts, fonts, images and vector images

Front 12

Advantages of bitmapped painting

Back 12

more control over textures, shading and fine detail

Appropriate for screen displays, simulating natural paint media, and embellishing photos

Front 13

Object Oriented Drawing

Back 13

gives you advantages such as cleaner lines and smoother shapes

Front 14

3-D Modelling software

Back 14

used to create 3D objects with tools similar to those in drawing software

Front 15

Computer-aided design (CAD)

Back 15

allows engineers, designers, and architects to create designs on screen products ranging from computer chips to public buildings

Cheaper, faster and more accurate that traditional design by hand techniques

Front 16

Computer Aided Manufacturing (CAM)

Back 16

process by which data related to the product design are fed into a program that controls the manufacturing of parts

Front 17

Computer Integrated Manufacturing (CIM)

Back 17

combination of CAD and CAM

Front 18

Dynamic Media

Back 18

information that changes over time or in response to user input

Animation, Video, Audio, Hypertext

Front 19

Presentation Graphics

Back 19

automates creation of visual aids for lectures, training sessions, sales demonstrations, and other presentations

Creates slideshows directly on computer monitors or LCD projectors, including still images, animation and video clips

Front 20

Tweening

Back 20

instead of drawing each frame by hand, the animator can create key frames and objects and use software to help fill in the gaps

Front 21

Vector Graphics

Back 21

is the creation of digital images through a sequence of commands or mathematical statements that place lines and shapes in a given two-dimensional or three-dimensional space

Front 22

Vector Graphic Formats

Back 22

Shockwave Flash Format (SWF)

Scalable Vector Graphics (SVG)

Front 23

Analog and digital video

Back 23

a video digitizer can convert analog video singals from a TV broadcast or videotape into digital data

Front 24

Storyboard

Back 24

describes the action, language, dialogue and music in each scene

Front 25

Adobe Premiere

Back 25

video editing software that makes it easy to eliminate extraneous footage, combine clips from multiple takes, insert visual transitions, superimpose titles, synchronize a soundtrack and create special effects

Front 26

Data Compression

Back 26

saves storage space, allows the processor to keep up with the quickly changing frames

Front 27

Image Compression Software

Back 27

compresses graphics and video files

ex. Quicktime

Windows Media Player

Front 28

Synthesized

Back 28

digital recording of computer sounds

Front 29

Sound data

Back 29

waveform audio

records sound which takes up a lot of space

records the number of sound snapshots the recording equipment takes each second

Front 30

Synthesizer

Back 30

electronic instrument synthesizes sounds using mathematical formulas

Front 31

Musical Instrument Digital Interface (MIDI)

Back 31

standard interface allows electronic instruments and computers to communicate with each other

ex. A piano style keyboard send its signals to the computer

Front 32

Sequencing software

Back 32

turns computer into musical composing, recording, and editing machine

Front 33

Virtual Instruments

Back 33

instruments that exist only in software

Front 34
