1. Camera Model If the focal length of a single-lens camera is 0.5 meter, the object has a height of 2 meters and the width of 1 meter. When the object is 10 meters away from the central projection point of the camera, what are the dimensions of the image?

2. Histogram Programming If the image has the greylevel values as {8, 2, 7, 9, 9, 6, 10, 7, 5, 5}, what is the result of Histogram Equalization if we need to expand the range of the greylevel values to the range of 1-20?
