CCD Cameras

Charged Coupled Devices (CCDs) manipulate the movement of electrical charges by changing the signals through the various stages within the device, later converting captured light into digital data. An image is projected onto a silicon epitaxial layer via the lens of a CCD camera, which acts as both a photoactive and shift transmission region. An electrical charge proportional to the light intensity of the image is produced and accumulated at each capacitor array within the device. Images detected by this capacity array enable this electrical charge to be transferred to various capacitors until it is finally converted into a sequence of voltages that can be sampled, digitalized and stored as memory onto the device.
