Understanding Bitmap Images 2 - yr8

What is a bitmap?

• A method to compress images

• A type of image filter

• A way to represent image data using pixels

• A type of vector graphic

In a monochrome image, what does a black pixel represent?

• 8

• 1

• 2

• 0

Why do early computers have poor quality images?

• They used 32-bit color

• They used high color depth

• They had large pixels and monochrome images

• They had high resolution

What is pixel density commonly referred to as?

• Image quality

• Bit depth

• Resolution

• Color depth

How many pixels are there in an image that is 100 pixels across and 100 pixels down?

• 1,000,000

• 100,000

• 10,000

• 1,000

How much memory does a monochrome image with 10,000 pixels require?

• 12,500 bytes

• 1,000 bytes

• 1,250 bytes

• 10,000 bytes

How many bits are used to describe the color of each pixel in an 8-bit color image?

• 8 bits

• 1 bit

• 16 bits

• 24 bits

How much memory does a 100x100 pixel image with 8-bit color require?

• 8,000 bytes

• 1,000 bytes

• 10,000 bytes

• 80,000 bytes

How many colors can be represented with 24-bit color?

• 16.7 million colors

• 1 billion colors

• 256 colors

• 65,536 colors

What are the two main factors that determine the quality of a bitmap image?

• Color depth and compression

• Resolution and color depth

• File size and resolution

• Resolution and file format
