Q

On a 17 inch monitor, we
could have 800 pixels (width) by 600
pixels (height) OR 1024 pixels by 768
pixels. Think about the size of the
dots/pixels
◦ Which resolution will have the bigger pixels?
◦ If we displayed this “E”, on which screen
would it look bigger: the 800by600 resolution or
the 1024by768 resolution

A

the 800 by 600 would have bigger pixels and the E would look bigger on this one too

108
Q

How do you convert analog to digital!?(two steps)

A
  1. Sampling

2. Quantizing

109
Q

what is sampling

A

the first step of converting analog dodigital, it is how often you take a sample/measurement to represent parts of the “thing”
deciding how many chunks to break the thing into

110
Q

what is quantizing

A

how many discrete values to use to represent the parts of the thing

111
Q

If an image is bad quality, does it have more chunks or less

A

less (it is broken up into fewer chunks)

112
Q

if you take 1 byte to represent each colour, how much space would that take
red, green blue

A

about 16 million bits

113
Q

how do we get images on our computer?

A

By scanning existing images (a drawing or an old photograph or a painting)
By taking a picture with our digital camera
By creating something original using MS Paint or Photoshop or some graphics program

114
Q

the more samples the __ the resolution

A

higher

115
Q

samples on scanners/printers are measured as

A

dots per inch (DPI)

116
Q

samples on monitors are measured as

A

pixels per inch (PPI)

117
Q

If we scan an 8 inch by 10 inch image at 100dpi, the image will be

A

(8100) * (10100) = 800*1000 = 800,000 samples or pixels(almost 1 million samples).

118
Q

what do we call a sample in an image

A

pixels

119
Q

pixels are..

A

the smallest possible image component and show the smallest detail
an image is represented by a grid (array matrix) of squared PICture ELEments (PIX ELS)

120
Q

If we scan that same 8 inch by 10 inch picture in and we set the resolution to 300dpi, after scanning, we will get

A

(8 * 300) * (10 * 300) = 7,200,000 pixels (about 7 million pixels)

121
Q

when printing an image, you should print with a dpi of at least

how many millions of pixels you can capture in a photograph on your digital camera (how mnay samples it will break the image nto

123
Q

If you want to print4” by 6” images, you don’t need much more than __ megapixels

A

3

124
Q

a camera with more megapixels can print a

A

larger image without the human eye detecting a loss of quality

125
Q

**when printing an image, the image must be printed at a min of **

A

300ppi

126
Q

if you have an image of 3000pixelsx1500 pixels, what is the largest size you should print a picture

A

Answer: 3000/300 –> 10 inches by 1500/300 –> 5 inches. DON’T PRINT IT ANY LARGER THAN 10” by 5”

127
Q

how does the pixel in image go onto screen or paper

A

we map IMAGE PIXELS onto the screen in a 1 to 1 mapping and see our image

128
Q

the screen resolution is

A

the num of pixels across by the numebr of pixels down that a screen is currently displaying

129
Q

common screen resolutions

A

640 by 480
800 by 600
1024 by 768
1280 by 1024

130
Q

what happens if you have a lower resolution

A

the size of fonts icons and images appear larger (easier to read) but you can’t fit as much data on the screen at one time

131
Q

what happens if you increase the resolution

A

smaller text and it is harder to read but you can fit more onto the image

132
Q

the amount of space that an image takes up depends on the

A

size of the image and the current resolution of the screen but NOT THE DPI

133
Q

what does the amount of space that an image takes up NOT depend on

A

NOT THE DPI

134
Q

an image is 400 by 300 pixels will take up__ of the screen on a monitor with 800 by 600 resolution

A

1/4

135
Q

an image is 400 by 300 pixels will take up__ of the screen on a monitor with 1000 by 1200

A

1/16

136
Q

the average pixels per inch for monitors depends on

A

the size of the monitor in inches and the current resolution

137
Q

the average ppi is*******

A

72

138
Q

why is 72 ppi the average

A

because if we always create an image at 72 ppi, we are guaranteed that what we see with the zoom level at 100% will be about the same size as on a typical screen as it would if we decided to print it.
