As a part of the research and revise step of the Legacy Cycle, this lesson provides students with information they will need later on to be able to average pixels to simulate blurring in the peripheral plane of vision. Students learn why image color becomes important as we distort the outer boundaries of an image and have to interpolate pixels to fill in gaps created from our algorithm. Students learn what a digital image is, what pixels are, and how to convert between RGB and hexadecimal values.
A digital image is a type of digital signal. The field of digital signal processing is a primary sub-field of electrical engineering and is applicable to many areas. Two such areas are medical imaging and communications (transmission of data). The hexadecimal number system is often used in the computer science and computer engineering fields as an alternative way to represent numbers.
After this lesson, students should be able to:
- Explain what a digital image is.
- Explain what pixels are.
- Convert the RGB value of a pixel to hexadecimal.
- Give specific examples of how engineers need this information to solve problems.
