Download丨Ambient brightness/color temperature/frequency detection sensor to optimize mobile phone camera performance
Smartphones have entered the stock market, and the ability to record and present images of a better life has become the most popular function for smartphones. It is conceivable that when consumers use their mobile phones to take certain pictures/videos, if "water ripples" of light and dark stripes appear, their favorability towards the phone will be greatly reduced. How to solve the "water ripples" and improve the performance of mobile phone cameras?
Mobile phone cameras generally use rolling shutter exposure mode. Under stable brightness, the longer the exposure time, the brighter the photo, and vice versa. When the brightness on the photosensitive surface changes regularly, inappropriate exposure time will cause the display to alternate between light and dark, and "water ripples" will appear.
The ams OSRAM brightness/color temperature/frequency detection sensor TCS3408 can accurately analyze the ambient brightness and frequency information, and transmit this information to the camera in real time, allowing the camera to set the appropriate exposure time according to the brightness and frequency information of the actual test environment, so that each exposure can obtain stable and uniform ambient brightness information, solving the problems of underexposure/overexposure and "water ripples"; especially when shooting videos, it can optimize the performance of the camera to the greatest extent and improve the display effect.
TCS3408 Technical Points
The TCS3408 ambient brightness/color temperature/frequency sensor can not only accurately obtain the ambient brightness and color temperature, assisting the camera to implement a more accurate white balance algorithm; it can also analyze the frequency changes of ambient brightness to determine the optimal exposure time setting.
-
Integrated CRGBW multi-channel; integrated interference filtering and absorption filtering technology to optimize the light splitting effect;
-
Noise suppression technology maximizes analog gain and improves signal-to-noise ratio;
-
Multi-channel ADC design, various functions are used in parallel, and mutual interference between functions is effectively eliminated;
-
The strobe channel filters out the IR component to eliminate the influence of the high-frequency infrared device on the rear of the mobile phone.
