2 AT76C451BC-MY15AT [preliminary] 5375as?image?06/04 description the AT76C451BC-MY15AT cmos camera module is a turnkey system ideal for mobile phones and pda applications. this complete image solution provides a vga standard image format using on-chip image processing that provides high-quality images. the module is integrated on an ultra-thin m odule and has a very low power consumption. the eye-on-si vga includes a digital zoom from 1 to 5 in up to 17 steps. this digital zoom is very progressive like those available in cameras that include an optical zoom. the image resolution is the same at each step and can be adapted to the output screen. the eye-on-si provides you with the ability to adjust the image pr ocessing functional - ities to obtain sharp and crisp images and to meet color fidelity requirements under various environmental conditions. automati c exposure control and automatic white bal - ance maintain the average luminance of the scene and the consistency of colors in different lighting. automatic flicker detection and cancellation eliminate perturbations due to modulation of an artificial light source with either a 50 or 60 hz voltage supply. the eye-on-si vga also includes a noise reduction algorithm called coring that elimi - nates video noise in the low-frequency part of the image. the device also features a very high level of readout functionalities by providing the same angle of view for standard image resolutions (cif, qcif, qvga, etc.). this enables video acquisition in cif format with the maximum angle of view. easy to integrate into any application, the eye-on-si vga operates with a single power supply and within a frequency range of 3 to 80 mhz thanks to its on-chip pll circuitry. easy to monitor, the on-chip functions and image processing are programmable through a two wire interface (twi). applications mobile phones/pdas dual mode cameras home phones notebook computers pc cameras camcorders toys
