VGAstands for Visual Graphics Array. This is a low resolution camera (640x480) pixels only. They were originally incorporated in some of the earlier mobile phones and external web-cameras, they are still incorporated today in some electronic devices that only require basic low resolution images (for example: time and attendance machines, some web cameras, pin-hole "spy camera's" and entry level digital microscopes). The maximum resolution on these cameras is in the region of 0.3 megapixles.

A "megapixel camera" probably refers to the use of a modern CCD(Charge Couple Device) or CMOS*(Complimentary Metal-Oxide Semiconductor) type image sensor.

These use a slightly different process to generate images and are dependant on the type of sensor, size of the sensor and software/ firmware that drives the operation.

Typically these are now incorporated in almost all modern imaging devices (digital cameras, satellites, mobile phones, television cameras etc.


* Note: that this is not the same CMOS that is found in the CPU of a laptop or PC.
