- 1. More Information in Images
- 5. Number of alternatives = 2 number of bits Log 2 Number of Alternatives = Number of bits
- 6. Number of alternatives = 2number of bits Log 2 Number of Alternatives = Number of bits But what is needed to store an image or other information..?
- 7. Capacity How much data is needed to store an image??? Windows tells us the size of a file, but why is it that value? Remember 1 Byte = 8 bits ( Bi nary Digi ts )
- 9. Image Capacity of available memory = Memory Available/ Memory Required for Image How many of these images could be stored onto a 20GB disc? 20 x 10 9 / 5.3 x 10 6 = 3774 images It doesn’t matter what the data is for; images, text or music. Capacity is calculated the same way…
