Finally Samsung developed new pixel technology called ISOCELL, with the help of ISOCELL Samsung able to increase the light sensitivity of the sensor.
 Previous sensor technology developments focused on improving the light absorption of each pixel, and have progressed pixel technology from FSI (Front Side Illumination) to BSI (Back Side Illumination) which places photodiode at the top to maximize photoelectric efficiency. While being very effective at the time, this BSI technology also faced limitations in improving image quality as pixel sizes continued to decrease. ISOCELL is the next generation of pixel technology, which is patent pending. ISOCELL technology forms a physical barrier between neighboring pixels – isolating the pixel. This isolation enables more photons to be collected from the micro-lens and absorbed into the correct pixel’s photodiode minimizing undesired electrical crosstalk between pixels and allowing expanded full well capacity (FWC).
Additionally, an imager designed with ISOCELL can feature a 20 percent wider chief ray angle (CRA), reducing the height of the camera module. This makes it suitable for slim and small form factor mobile devices with challenging low z-height requirements.
As the first Samsung image sensor to adopt this new technology, the S5K4H5YB 8Megapixel imager utilizes a 1.12um ISOCELL pixel and has a 1/4inch optical format. The S5K4H5YB is currently sampling to customers with mass production scheduled for Q4 2013.
According to market research firm Techno System Research, in 2014, approximately 66 percent of smartphones will feature image sensors with 8Mp or higher resolution.

 Both the BenQ camera uses Sony Sensors, BenQ GH600 uses 16 Megapixel CCD sensor whereas BenQ GH700 comes with 16 Megapixel BSI CMOS Sensor, Due to BIS CMOS Sensor you get better low light performance, HDR mode and Full HD movie mode. CMOS sensors uses less power compared to CCD sensors hence you get better battery life in GH700, Read the comparison review below for detail specification comparison.
 BenQ GH 600 vs BenQ GH700 comparison review
The BenQ GH600 comes with CCD sensor whereas the BenQ GH700 comes with The back – illuminated BSI CMOS sensor increases sensitivity by two times and minimizes the noise level by up to 50%, delivering stunning results in low – light situations.
The GH700 features a high-speed, high – efficiency digital signal processor (DSP) that enhances the processing speed by up to 30%.
The BenQ GH600 captures 720p HD @ 30fps with sound whereas BenQ GH 700 1080p Full HD videos at 60fps with Stereo Sound.
GH700 has a built-in wind cut function so audio recorded can have minimum unwanted background noise.
