Mobile Camera Controller - CST21C01

▶ Overview

Recently, Many electronic portable devices are equipped with camera functions more and more. MP3 Player, Toys, Cellular Phone, PDAs, Laptop, etc ..
The SPY-V provides more variable camera functions and has easy architecture to develop any portable device. It supports the variable resolution up to VGA at maximum frame rate of 30 Frames/sec. It is provided with small package size, low cost, low power consumption, and best fit to any kind of portable electronic equipments. The variable camera functions which are Real Digital Zoom up to 160 steps size, fully hardwired real-time JPEG Codec, Color Filters, Effecter, 1Pixel Step Linear Scaler, Gamma Correction, Sensor Interface, LCD Interface, PIP function, TWSI(Sensor Communication), GPIO(Port 7), LDO and PLL are included in the SPY-V.
Through these efficient technologies and functions, developers can implement such as still images, moving images in cooperation with various types of camera and API solutions.
