Sony FCB camera block
As we all know, the large target surface of SONY FCB-ES8230 is mainly reflected in the size of their 1-inch CMOS sensor. This size has significant advantages over other common target surface CMOS sensors such as 1/1.8 inch, 1/2.5 inch, 1/2.8 inch.
For the topic of integrated camera module low light performance, Danny Wong, senior engineer of Xuan Zhan Technology, conducted an in-depth discussion from the following aspects.
The importance of low light performance
Low light performance is one of the important indexes to measure the performance of integrated camera module. In dim light environments, such as at night or dark indoors, the camera’s better low-light performance can improve image clarity, enhance color reproduction capabilities, and expand the range of applications.
Therefore, for night patrol, aerial photography, underwater detection, wildlife observation, security monitoring and other fields, to improve the low-light performance of the camera has more important significance.
Advantages of large target surface
1. more sensitive area
SONY FCB-ES8230, 1-inch sensors have a significantly increased sensitive area compared to smaller target surfaces. The sensitive area is one of the key factors to determine the quality of the image, and a larger sensitive area can capture more light, thereby improving the clarity and detail of the image.
2. better low light performance
In low light environments, the larger sensitive area of the SONY FCB-ES8230 can reduce noise, improve image purity and contrast, and make the picture clearer and more delicate.
3. Higher pixels and resolution
SONY FCB-ES8230 approximately 20.5 million pixels allow them to capture more image information, providing more space for post-processing and editing.
Moreover, due to the increase in the sensitive area, the 1-inch sensor can accommodate more pixels, thus providing higher resolution. Both the FCB-ES8230 support 4K ultra HD resolution (3840×2160), allowing for more detail and layers.
4. better color reproduction
The larger target surface helps to improve the color reproduction ability, making the picture more vivid and realistic. The larger target surface of the FCB-ES8230 generally means a higher dynamic range, enabling the image to maintain detail and color balance in high-contrast scenes.
Large target surface SONY FCB-ES8230 for better color reproduction
Due to the significant advantages of 4K ultra HD resolution and large target surface, SONY FCB-ES8230 have demonstrated excellent performance and a wide range of application values in the fields of broadcast/video, high-end conferencing, medical equipment, security monitoring and high-precision detection.
The large target surface of SONY FCB-ES8230 does have a positive impact on their performance in low light environments, but it cannot be directly concluded that their low light performance must be good, because the low light performance of the integrated camera movement is also affected by a number of factors.
1. Sensor type:
Different types of image sensors, such as CMOS and CCD, may behave differently in low-light environments. The same CMOS sensor, different versions of low light performance is not the same, Exmor R CMOS sensor (SONY FCB-EV7520 and other cameras) due to the use of backlighting structure, Higher sensitivity than front-facing Exmor CMOS sensors (SONY FCB-EV7500 cameras, etc.) for better image performance in low-light environments.
STARVIS CMOS, a new low light sensor technology launched by SONY, has higher sensitivity and color reproduction ability, sensitivity increased by about 2 times, can provide better image quality in low light environment, has better starlight night vision function, and can still output color images at 0.01Lx low light. Minimum illumination up to 0.00008Lx. For example, SONY’s new integrated camera module FCB-ER9500, FCB-EV9520L, FCB-EW9500H, etc., all use STARVIS CMOS series image sensors.
2. Lens quality:
The aperture and shutter of the camera lens are used to control the amount of light, the greater the amount of light, the stronger the sensitivity, the better the low light performance, that is to say, the shutter exposure time is longer, the aperture can also enhance the low light performance of the camera. However, it should be noted that in the adjustment process, it is necessary to pay attention to all aspects of the image to obtain high-quality images, such as noise, brightness, clarity, etc.
3. Image processing technology:
Advanced image processing algorithms and techniques can further improve image quality in low light environments. For example, noise reduction algorithms can reduce noise while preserving image detail; Automatic exposure and gain control technology automatically adjusts exposure and gain levels according to light conditions.
SONY’s image processing algorithms and technologies are constantly improving and optimizing, the recently launched 4K/60FPS integrated camera core module FCB-ER9500, using the latest image processing technology, can cope with the complex environment of low light at night, and can output more real color images. Especially in automatic mode, image processing technology can automatically control and adjust the noise, exposure, gain, white balance and color correction of the camera, so that the image is more clear, bright and close to the true color.
Conclusion:
SONY FCB-ES8230 have certain advantages in low light environments due to the use of large target surface CMOS sensors. However, its low-light performance also depends on a number of factors such as the type and version of the sensor, lens quality, and image processing technology.
Therefore, these factors need to be taken into account when evaluating its low-light performance. At the same time, it is worth noting that different application scenarios have different requirements for low light performance, so it is necessary to choose the right camera module according to the specific needs in practical applications.
