General Description
The OV7725FSL/OV7725FSL1 is a sensor on-board
camera and lens module designed for mobile applications where low power consumption and small size are of utmost importance.
Proprietary sensor technology utilizes advanced algorithms to cancel Fixed Pattern Noise (FPN), eliminate
smearing, and drastically reduce blooming. All required camera functions are programmable through the serial SCCB interface.
The device can be programmed to provide image output in various fully processed and encoded formats.
The OV7725FSL/OV7725FSL1 features the OV7725C AMERA C HIP TM sensor. Refer to the OV7725 Datasheet for chip-specific information.

Sensor Imaging Functions Description
Auto Exposure
Module automatically sets correct exposure time.
Auto Exposure ON/OFF Auto exposure can be turned off so the exposure can be set manually.Auto White Balance (AWB)AWB without companion processor interaction.Auto White Balance OFF AWB can be turned off.
Color Correction
It is possible to adjust for the color filter response of the image sensor as well as for human eye sensitivity.
Bayer Pattern Interpolation (Mosaic or equivalent) The interpolation must be done prior to downsizing the image to avoid artifacts due to incorrect interpolation.
Electrical Illumination Flicker Elimination Interference from 50Hz or 60Hz illumination can be suppressed with manually set frame rate divider.Gamma Correction Built-in 0.45/1.0
Color Space Conversion Bayer raw RGB is converted to YCbCr/YUV color space.
Image Size Decimation Size can be altered using the windowing registers. Quarter-format sub-sampling is also provided.
Image ON/OFF Image ON/OFF can be controlled by register settings.Vertical Flip

Handling Precautions
?DO NOT try to open the unit enclosure as there is no user-serviceable component inside.?
To prevent damage to the camera module by electrostatic discharge, handle the camera module ONLY after discharging ALL static electricity from yourself and ensuring a static-free environment for the camera module.
?DO NOT touch the top surface of the lens.?DO NOT press down on the lens.?DO NOT try to focus the lens.
?DO NOT put the camera module in a dusty environment.
?To reduce the risk of electrical shock and damage to the camera module, turn OFF the power before connect and disconnect the camera module.?DO NOT bend the flex cable in a sharp angle.?DO NOT twist the flex cable.
?DO NOT peel the flex cable when you install and uninstall the camera module.?DO NOT drop the camera module more than 60 cm onto any hard surface.
?To prevent fire or shock hazard, DO NOT expose camera module to rain or moisture.?DO NOT expose camera module to direct sunlight.
?DO NOT put camera module in a high temperature environment.?DO NOT use liquid or aerosol cleaners to clean the lens.?DO NOT make any changes or modifications to camera module.?DO NOT subject camera module to strong electromagnetic field.
?
DO NOT subject the camera module to excessive vibration or shock.
