According to the conservative estimation of the trade, there are at least 30% cameras fake Sony CCD, while in the low-end market is far more than that number. We always meet the situation that merchants palm off Sharp CCD as Sony CCD. In this way, the merchants can make more profit because the Sharp CCD is much cheaper than Sony CCD.Here we have two simple and easy methods to recognize the Sharp CCD and Sony CCD First, check its appearance—if it`s box camera, we can open the shield and observe the CCD surface and junction up and down

It is obviously that SONY CCD is less one box of the middle in both junctions of up and down, which is one of features of SONY CCD; SHARP CCD has regular full junctions; PANASONIC also has regular full junctions but with rough lines; while the KOREAN A1 has golden color junctions with two boxes less, but more narrow. KOREAN A1 is the same pincompatible with SONY CCD 405, which is the best substitute of SONY but with much worse quality.

Second, watch the image—generally speaking, the same 1/3 CCD, SONY is real and brighter in color while SHARP has serious color difference. With dark light, SONY CCD produce small noisy images but SHARP CCD is opposite.The two pictures baelow are collected by 8050 card from SONY CCD camera and SHARP CCD camera.
