Bitmap images (improved)

Tiny squares called ___________ are the building blocks of all digital images.

• elements
• dots

• pixars
• pixels

When we have a 'one-bit' colour, which are the only two binary numbers that are possibilities?

• 00 and 11
• 000 and 111
• 0 and 1
• 0000 and 1111

How many combinations are there for a '2 bit' colour?

• 8
• 4
• 16
• 32

A bitmap image is made up of

• Pixels

• Colours

• Sounds

• Samples

How many colours can be used for each pixel if the colour depth is 8 bit?

• 8 colours
• 9 colours
• 255 colours
• 256 colours

Additional Information about the image file is stored as

• Metadata
• Properties
• File summary
• Pixels

The number of pixels per inch in an image is known as the

• Dimensions
• Colour depth
• Resolution
• Megapixels

Increasing the resolution of an image means that

• More pixels will be used to make up the image
• More colours will be used to make up the image
• The image size will be bigger

Which is NOT an effect of increasing the resolution in an image?

• More colours can be displayed.
• More binary will be required to create the image.
• Larger file size
• Higher quality image

Colour depth defines...

• How many bits are needed to store each pixel

• How many pixels are in an image

• The file size of a bitmap image

• The sample rate of sound
