Image Acquisition
Definition
In this phase we acquire the image using some digital image sensors and then to convert it from the analog form to digital form we use specialised image processing hardware.
Types of Sensors
- Single Image Sensors: A single sensor is used sensing the image.Here the sensor has to move in both x and y directions to capture the whole image area.
- Sensor Strips: A single strip of n sensors are taken and then these strip can trace the x-direction perfectly so the only movement required is in the y-direction.
- Sensor Arrays: Here 2-d arrays of N x N sensors are used to capture the entire image.This finds application in most modern day cameras.
