1. Look at the binary code given that has been used to create the image sequence. Which line has not been represented correctly?
2. The colour depth of an image is measured in bits. The number of bits indicates how many colours are available for each pixel. In the black and white image, only ___ colours are needed. This means it has a colour depth of 1 bit. (1 bit can be either 0 or 1
3. A 2-bit colour depth would allow ______ different values: 00, 01, 10, 11. This would allow for a range of colours such as shown in the image below.
4. So what about the human eye? Some experts estimate that we can distinguish perhaps as many as 10 million colors. Others estimate about 1 million, but 10 million is the top estimate. True or False?
5. The image below shows a creative website that made a million dollars by creating a website with a million pixels and selling pixels to customers. What is a pixel?
6. True or False? The more pixels on the screen, the higher the resolution and the better the quality of the picture will be.
7. Image files can be either bitmaps or vectors. Which of the following statements are true of bitmap images?
8. Each colour of an image is stored as a binary number. In the black-and-white image below, each pixel is either_________________________________
9. In the image below, what represents a black square?
10. For a simple black and white bitmap image, you only need 1 bit. A 0 could represent a white pixel and a 1 could represent a black pixel. Remember that 1 bit can be either "on" (0) or "off" (1).
11. Read the excerpt below and see if you could suggest a solution to the given problem.
12. The greater the colour depth (bits per pixel), the more colours are available.From the table below how many colours would be available with a colour-depth of 8 bit?
13. Most computer systems and digital cameras use _____-bit images. ______ in binary is 1111 1111 1111 1111 1111 1111. This means there are over 16 million possible colours per pixel.
14. __________ is a measure of pixel density, usually measured in dots per inch (dpi). Images on websites usually have a ____________ of 72 dpi.
15. High quality printed images in books and magazines have a ________ resolution than computer screens. Magazines often use either 300 dpi or even 600 dpi.
