Current smart phone cameras will typically have around 8 Mpix resolution. How does this compare to the VideometerLab 5, 6 and 9.1 Mpix? Obviously it is quite different devices and for different uses, but we will outline the major differences in the camera sensor. The camera sensor is obviously only a small yet important part of a VideometerLab spectral imaging instrument. Comparing specs of the sensor chip in the camera with commodity cameras may be useful in avoiding misinterpretations. When your smart phone camera specs at 8 Mpix, then this means that the camera chip has 8 million pixels. These are divided between the red, green and blue channels through a Bayer mosaic filter on the camera chip (as shown in the image above). This will typically mean that there are 4 million green pixels, 2 million red pixels and 2 million blue pixels. If you compare this to the VideometerLab with 6 Mpix per channel and 20 channels then VideometerLab is equivalent to a 120 Mpix camera as 120 million pixel values are sampled in every image. Another difference is the pixel sensor area. Current smart phones may e.g. have a pixel sensor area on the chip of 1.5 x 1.5 micron, and the VideometerLab cameras have a size of 3.5-5 micron squared. Thus the VideometerLab will typically have 5-10 times higher pixel sensor area and thus 5-10 times higher sensitivity.
