An industrial machine vision camera (either CCD or CMOS) consists of a light sensitive sensor (CDD array) that converts incoming photons into electrical signals. These than pass through an A/D converter, (analogue to digital converter) before being transfered out of the camera. CCDs (Charge Coupled Devices) can be either frame transfer devices, interline transfer devices or full frame devices. Standard sensor resolutions include: VGA = 640x480, SVGA= 800x600, XGA = 1024x768 and SXGA = 1280x1024</h3>
<p> High Dynamic Range refers to the number of distinct grey level that a camera can distinguish between. This is normally expressed as 'bit depth', where 8bit =256 levels, 10bit = 1024 and 12bit = 4096. There are a number of circumstances where an HDR camera may be required. It could be that the image analysis needs to differentiate between very subtle image details that a camera with a standard sensor cannot, or it might be that camera needs to have extremely high sensitivity or a very fast speed. This section also covers X-Ray sensitive cameras. </p>
