A

Video

23
Q

An interactive three-dimensional world that dynamically changes as the “user” moves through and views it.

A

Virtual Reality

24
Q

A

Communication Function

25

32
Q

human learning processes such as attention or retrieval from memory

A

Cognitive Psychological Function

33
Q

reducing of
quality of image

A

Lossy Compression

34
Q

it does not allow the image to dramatically lose its appearance

A

Lossless Compression

35
Q

Very flexible format that can be lossless or lossy

Details of the image storage algorithm are included as part of the file

Used almost exclusively as a lossless image storage format that use no compression at all

Sometimes a lossless compression algorithm called LZW is used,
but it is not universally supported

A

TIFF
(Tagged Image File Format)

36
Q

Also a lossless storage format

In contrast with common TIFF usage, it looks for patterns in the image that can be used to compress

File size compression is exactly reversible, so the image is recovered exactly

A

PNG
(Portable Network Graphics)

37
Q

Can render the image exactly if the image has fewer than 256 colors

When the image contains many colors,the software that creates the GIF uses any of several algorithms to approximate the colors in the the limited palette of 256 colors available

A

GIF
(Graphic Interchange Format)

38
Q

Optimized for photographs and similar continuous tone images that contain many, many colors

Can achieve astounding compression ratios even while maintaining very high image quality

Works by analyzing images and discarding kinds of information that the eye is least likely to notice

A

JPG
(Joint Photographics Expert Group)

39
Q

An image output option available on some digital cameras

Disadvantageous because there is a different RAW format for each manufacturer, and so you may have to use the manufacturer’s software to view the images

A

RAW
(Portable Network Graphics)

40
Q

An uncompressed proprietary format invented by Microsoft

A

BMP
(BITMAP)

41
Q

Proprietary formats used by graphics programs Preferred working formats as you edit images in the software, because only the proprietary formats retain all the editing power of the programs

A

PSD or PSP
(Photoshop Documents or Paint Shop Pro)
