Overview

The VL6624/VS6624 is a SXGA resolution CMOS imaging device designed for low power

systems.

Manufactured using ST 0.18 µm CMOS Imaging process, it integrates a high-sensitivity pixel

array, a digital image processor and camera control functions.

The VS6624 is capable of streaming SXGA video up to 15 fps, with ITU-R BT.656-4 YUV

4:2:2 frame format. It supports both 1.8 V and 2.8 V interface and requires a 2.4 to 3.0 V

analog power supply. Typically, the VS6624 can operate as a 2.8 V single supply camera or

as a 1.8 V interface / 2.8 V supply camera. The integrated PLL allows for low frequency

system clock, and flexibility for successful EMC integration.

The VS6624 camera module uses ST’s 2nd generation “SmOP2” packaging technology: the

sensor, lens and passives are assembled, tested and focused in a fully automated process,

allowing high volume and low cost production.

The device contains an embedded video processor and delivers fully color processed

images at up to 15 frames per second SXGA and up to 30 fps VGA.

The video data is output over an 8-bit parallel bus in RGB, YCbCr or bayer formats.

The VL6624/VS6624 requires an analogue power supply of between 2.4 V to 3.0 V and a

digital supply of either 1.8 V or 2.8 V (dependant on interface levels required). An input clock

is required in the range 6.5 MHz to 54 MHz.

The VL6624/VS6624 is controlled via an I²C interface.

It also includes a wide range of image enhancement functions, designed to ensure high

image quality, these include:

●

Automatic exposure control

●

Automatic white balance

●

Lens shading compensation

●

Defect correction algorithms

●

Demosaic (Bayer to RGB conversion)

●

Colour space conversion

●

Sharpening

●

Gamma correction

●

Flicker cancellation

●

NoRA Noise Reduction Algorithm

●

Intelligent image scaling
