ABSTRACT
In digital photography, the desired size of the captured objects can be obtained by adjusting the camera optics and/or using the digital image resizing techniques. In the former case, the distance between the lens and the sensor’s surface is adjusted in order to project the light corresponding to the captured visual scene onto a sensor under certain magnification. Increasing the focal length magnifies the objects in the scene while reducing the focal length produces photos with smaller objects. In the latter case, captured images are resized using specialized image processing algorithms.
