C280 is a black shell version of c800, and the software and hardware are the same.

280 is to meet the aesthetic needs of different people. After all, not everyone likes pure white design.

The imaging chip of c280 is cmos.

Complementary metal oxide semiconductor

complementary metal oxide semiconductor

Refers to the manufacturing process of complementary MOS integrated circuits composed of complementary metal oxides (PMOS and NMOS transistors), which is characterized by low power consumption. Because the gate composed of a pair of MOS in CMOS is turned on by PMOS, NMOS or both at the same time, the efficiency is much higher than that of linear triode (BJT), so the power consumption is very low.

The imaging chip of c800 is ccd.

Charge coupled device. CCD is a semiconductor device, which can convert optical images into digital signals. The tiny photosensitive substances implanted on CCD are called pixels. The more pixels a CCD contains, the higher the image resolution it provides. The function of CCD is just like film, but it converts image pixels into digital signals. CCD is widely used in video cameras, digital cameras and scanners, except that the camera adopts dot matrix CCD, that is, it includes X and Y directions for shooting plane images, while the scanner adopts linear CCD, and the scanning in X direction is only completed by the mechanical device of the scanner.

Generally speaking, the shooting effect of CCD is much better than that of CMOS, so C280 can be understood as the low-end goods of C800. Otherwise, there is no obvious difference between the two mobile phones.
