Zeroplus Technology, a leading brand for PC -Based Logic Analyzer, recently releases new Protocol Analyzer CMOS IMAGE. 　The research for CIS(CMOS Image Sensor) has begun in 1960, but it couldn’t be applied because the programme technology was not developed. Until 1990, since the VLSI Technology was developed, the industry began to pay much attention to CIS and developed it into application. Now it has three types: CMOS-PPS (CMOS Passive Pixel Sensor), CMOS-APS(CMOS Active Pixel Sensor), MOS-DPS(CMOS Digital Pixel Sensor). 　 　CIS(CMOS Image Sensor) IC is mainly applied for the cell phone lens, the camera lens, the internet monitor, the car monitor and so on. At present, there are many inland CIS providers (such as TASC, Elec Vision, IC-Media, Pixart and so on) and abroad providers (such as Angilent, Hynix, Motorola, Omnivision and so on). CIS IC can capture the video through transmitting digital signals, and then send the video to the displayer. Now, the COMS-APS occupies much of the current market. 　Protocol Analyzer CMOS IMAGE of Zeroplus Technology can analyze the transmission control signals of CMOS IMAGE and display the Lightness of Horizontal/Vertical Synchronization Line in CIS in the form of Packet, so as to understand the Lightness value of every pixel of pictures in CIS video. Protocol Analyzer Analysis Module of Zeroplus can display the packet in graphical mode, the time to decode and calculate by hand can be saved in this way.
