S5K4AW CMOS Image Sensor - 1

The Samsung S5K4AW CMOS image sensor was designed from the ground up to offer excellent performance in high-definition video applications. Excellent Pixel Technology Increases Image Quality for PCs Performing Real-Time Video Capture The new Samsung S5K4AW CMOS image sensor takes imaging technology to new levels through its capabilities in real-time high-definition video capture. This highly integrated 1/4-inch system-on-chip imager for notebook and desktop computers includes innovative technology that improves the performance and resolution of currently available PC video solutions. Rather than the usual 1.3-megapixel resolutionbetter suited to still image captureחthe Samsung imager's 1.2-megapixel performance is optimized for high-quality video. It has broad applications in business video conferencing, Internet video sharing, direct-to-web scanning, biometrics and security. The S5K4AW camera chip includes the CMOS image sensor, an image processor and an 8-bit ITU-R 656/601 parallel interface. It is fabricated using Samsung's 0.13um CMOS image sensor process, which was developed for high efficiency and low power. The chip's design drastically reduces fixed-pattern noise and random pixel noise. Advanced Binning technology With its focus on high-definition video for the S5K4AW, Samsung developed a technique in which binning is performed in 2x2 pixel groups, enabling the imager to display standard VGA formats without the need for cropping. As a result, no longer will the top or bottom of a scene be lost during video conferencing or file sharing on social networks like YouTube. Low light sensitivity is an ongoing challenge in advanced video conferencing applications. However, Samsung's binning technology also significantly improves the imager's sensitivity to light. For example, the industry's standard binning approach improves light sensitivity by approximately 1.2 times but Samsung's technology boosts sensitivity by nearly three times. This is critical when the only illumination in a scene might come from the computer screen. s5K4Aw CMQs Image sensor photoplane 1280 (Horizontal) x 960 (Vertical) Active Pixels 640 (Horizontal) x 480 (Vertical) Smart Binned Pixels 1/4" Optical Format Programmable Analog & Digital Gain Programmable Exposure Control 12-bit ADCs o) z 2 -si z n ■a c r r n o 3 3 c 3 c 0 3 s i host i control line buffers image flow pipeline White Balance Correction Lens Shading Correction Defect Correction Flicker Adaptation Color Demosaicing Scaling Color Space Conversion o C w y ■a 0) s c s parallel I output I
