Cameras are indispensable equipment in modern life, they are widely used in security monitoring, medical equipment, drones, video conferencing and other fields. SONY autofocus cameras are favored by the market for their excellent performance and reliability. Among them, the white balance function is an important feature of SONY auto focus camera, which plays a key role in ensuring that the color representation in the camera image is true and accurate.

Understanding white balance
What is white balance? White balance is a function that adjusts the color balance of the camera, its purpose is to correct the color deviation under different light sources, so that the white in the image looks realistic. The color temperature is different under different light sources, such as higher daylight color temperature and lower incandescent color temperature. If the camera does not perform white balance correction, the white in the image may be biased towards blue or yellow, resulting in color distortion throughout the image.
Technical principles of white balance
SONY Autofocus camera white Balance is a technique that automatically adjusts the color temperature Settings of the camera to ensure that white in the image looks realistic and natural. Its technical principle involves the following aspects:
Color temperature measurement: The SONY autofocus camera measures the color temperature of the light in the scene through a photosensitive element such as CCD or CMOS. Color temperature is the relative heat of a light source color measured in Kelvin (K). Different light sources, such as daylight, incandescent or fluorescent lamps, have different color temperature values.
White reference: SONY autofocus cameras require a white reference to determine the color temperature of the light and to correct the white balance. This white reference should be a known, pure white object, such as a specialized white card or a white wall.
Automatic white Balance algorithm: SONY Auto focus cameras use an automatic white balance algorithm to automatically adjust the color temperature Settings of the camera based on the color temperature measurement results and white reference information. The algorithm can automatically increase or decrease the gain of the three color channels of red, green, and blue according to the color temperature of the light source in order to produce true white in the image.
Principle of auto focus camera white balance
White balance Settings: SONY Auto focus cameras usually offer a variety of white balance Settings options, such as automatic, indoor, outdoor, automatic tracking white balance, sodium lamp (fixed/automatic/outdoor automatic) white balance and manual white balance (MWB). The automatic white balance function allows the camera to automatically adjust the color temperature setting based on the light source in the environment. Preset white balance allows the user to set the white balance in advance according to the specific environment or needs. Manual white balance allows the user to manually adjust the color temperature Settings of the camera according to the actual situation.
Color correction: In addition to adjusting the color temperature of white, SONY auto focus cameras also require color correction to ensure that other colors in the image remain accurate and natural. Color correction is usually achieved by adjusting the color matrix or color gain of the camera.
SONY Auto focus camera’s white balance technology measures the color temperature of the light source in the scene, uses an automatic white balance algorithm, and automatically adjusts the color temperature setting of the camera based on the information of the white reference to ensure that the white in the image looks realistic and natural. At the same time, color correction also ensures the accuracy and naturalness of other colors. These technologies work together to enable the camera to capture true colors and produce high-quality images.
The role of white balance
The SONY Auto focus camera’s white balance features several advantages:
1, it can automatically detect the ambient light source and adjust it in real time, without manual intervention, convenient and fast.
2, it can be customized according to different environment and application requirements, to meet the individual needs of users.
3, the SONY Auto focus camera’s white balance function not only ensures that the white in the image looks real, but also accurately restores other colors. It is able to automatically adjust the color Settings of the camera according to the lighting conditions of the scene to ensure that the various colors in the image remain accurate and natural. So that users can truly feel the color of the scene being filmed.
4, Sony FCB camera also provides a variety of white balance modes, such as automatic white balance, indoor white balance, outdoor white balance, sodium lamp white balance, etc., to adapt to the needs of different scenes.
SONY 9 Series HD Autofocus camera modules, including: FCB-EV9520L, FCB-EW9500H, FCB-EV9500M, and FCB-EV9500L have the automatic area white balance function. This function means that the camera can independently adjust the white balance according to the lighting conditions in different areas of the scene. This capability can further improve the color accuracy and naturalness of the image, especially in complex scenes with different light sources or lighting conditions.
The importance of the white balance function cannot be underestimated. A good white balance adjustment can provide a more realistic color representation, making the image more visually appealing and believable. Especially in the field of surveillance and security, accurate color representation is crucial for identifying and tracking targets. In addition, in scenarios such as video conferencing and distance education, authentic colors can enhance the user experience and make communication more natural and comfortable.
The SONY auto focus camera’s white balance plays a crucial role in ensuring true color. Through advanced technology and outstanding performance, it is able to automatically adjust the white balance Settings of the camera to ensure that white and other colors in the image remain accurate and natural. This makes the captured images more realistic and vivid, and brings a better experience to the user.
