Which Technology Creates Holograms That You Can Interact With In The Real World?

Is an algorithm that reduces the size of digital media files?

CodecsCodecs are compression algorithms that reduce the size of digital media files.

The most common audio codecs include MP3, which is the most common format for music files, and AAC, which is primarily used by Apple iTunes..

Is the number of pixels an image holds?

When you set the pixel dimensions and the resolution, Photoshop creates a different physical size. The image holds the number of pixels in the image and number of pixels per inch you specified. The files size changes because you are changing the total number of pixels in the image and the number of pixels in each inch.

Which technology uses fiber optic cable to carry digital signals to your home?

(digital subscriber line)—Internet access over telephone lines designed to carry digital signals. DSL speeds range from 384 Kbps to 7 Mbps. (Fiber Optic Service)—Internet access over fiber optic cables.

Which type of camera uses a mirror?

SLR cameraA cross-section (or ‘side-view’) of the optical components of a typical SLR camera shows how the light passes through the lens assembly (1), is reflected by the mirror (2) placed at a 45-degree angle, and is projected on the matte focusing screen (5).

What is the distance at which subjects in front of the lens are in sharp focus?

focal lengthfocal length: The distance where subjects in front of the lens are in sharp focus.

Which type of compression results in a file that can be decompressed with no loss of data?

Lossless Compression6.4. 4.1 Loss and Lossless Compression and Decompression Lossless compression is a compression technique that does not lose any data in the compression process. Lossless compression “packs” data into a smaller file size by using a kind of internal shorthand to signify redundant data.

What term means the distance where subjects?

Focal Length. the distance where subjects in front of the lens are in sharp focus (by changing or moving the lens) Autofocusing. when you point the camera at your subject, the camera will automatically adjust the focal length by using a small motor to move the lens in or out. Fixed-Focus.

Which type of camera has a lens with a preset focal length that focuses well on objects within a specific distance?

Auto focus cameraAuto focus camera have lens with pre-set focal length that focuses well on objects within a specific distance. Zoom can be either optical or digital, but not both. Once image compressed using lossy compression can’t be fully restored to original.

Which term describes the number of pixels in an image?

resolutionThe term resolution refers to the number of small squares, known as pixels, that describe an image and establish its detail. Resolution is determined by pixel dimensions, or the number of pixels along the width and height of an image.

Which type of lens would be best for shooting a beach scene?

It’s vacation time and you’re hitting the beach! In order to capture the essence of a broad reaching beach and tide, you are going to want a good wide angle lens, such as a 17-40mm. At the same time, you may also want a good telephoto lens that gives you the option to zoom in on a variety of subjects.

What is it called the smallest square of color in an image?

A: In digital imaging, a pixel(or picture element) is the smallest item of information in an image. … The intensity of each pixel is variable; in color systems, each pixel has typically three or four components such as red, green, and blue, or cyan, magenta, yellow, and black.

Which feature results in sharper images?

Aperture and shutter speed. Sharpness comes into the picture because the aperture setting also controls depth of field while shutter speed also affects how movement registers. To maximize sharpness, you would generally want to use a small aperture (f/16-22) and a fast shutter speed.

Which audio format is the default file type used by Apple’s iTunes software?

By default, iTunes uses AAC (Advanced Audio Coding) format, but you can change the format as well as other import settings. iTunes supports HE-AAC files (also called MPEG-4 AAC files).
