One can only assume that the popularity of CMOS is mainly because they are more prevalent in security IP-cameras. The difference between CMOS and CCD chips is the CMOS outputs its information in digital format and requires less power to operate. These features will play heavily in the design of IP-cameras. As for the imaging […]
Status of the CMOS Image Sensor Industry 2014 – Product Image “A 10% CAGR is forecast for the CMOS image sensor market from 2013 – 2018” As major technology changes continue to reshape the industrial landscape, a 10% CAGR is forecast for the CMOS image sensor market from 2013 – 2018. The market will reach a total value of US$13B by 2018, driven by consumer and automotive applications. Many different applications are driving CMOS image sensor integration. It’s likely that the consumer market will benefit from new mobile technologies. As such, we foresee consumer applications (tablets, DSC etc.) to be the growth driver over the next five years (which is the opposite of the previous five years, which were driven exclusively by mobile applications). Moreover, after being dominated by CCD, DSC applications are now shifting towards CMOS. And while DSLR will be a substitution market, the next wave is likely to be automotive applications, which could become CIS’ third big market. Indeed, the CIS sensor market in automotive is showing steady growth, which is expected to continue in the coming years; possibly become CIS’ third-largest CIS market. Automotive also demands new technologies such as high dynamicrange sensors and near infra-red response, and will benefit (with appropriate optimization) from technology developments in the handset market. A shift from driving assistance applications to security-based applications may imply significant quality and reliability design improvements in the near future, possibly leading to traditional automotive product providers entering the market with more exuberance. Many […]
Brigates (Chinese name – Rui Kunshan Microelectronics Inc.) announces BG0601 and BG0631 MCCD sensors for PAL-resolution security cameras. MCCD is a CMOS sensor which has CCD-compatible external interface. It be used in place of CCD in security camera, with some modifications: AFE is integrated onto the sensor and HV driver is not needed: Brigates Chairman Luo Wenzhe presents MCCD technology

At the same number of pixels, CCD sensors have outperformed CMOS sensors in sensitivity; CCD sensors also take in more light than CMOS sensors of the same size. In real-world applications, however, CMOS sensors deliver the same level of performance as their CCD counterparts in low-light cameras. This makes CMOS sensors the preferred image sensor for HD cameras. What to Look for in a CMOS Sensor In theory, CCD sensors allow a higher resolution than CMOS sensors of the same size. In practice, image sensor suppliers overcome this simply by making larger image sensors since security cameras do not have space constraints. Major image sensor suppliers for the security market like Aptina, Omnivision, Sony and Sharp, use this advantage to continue to enhance the performance of CMOS image sensors. Currently, most HD cameras on the market use 1/1.8”, 1/2.5”, 1/2.7” or 1/2.8” image sensors. By testing IP megapixel cameras on the market, it is possible to find a CMOS sensor that is practical in both price and performance.
