Introduction
Interpretation of the National Standard of the People's Republic of China GB/T 16697—2017
1. Analysis of Standard Background and Technology Evolution
GB/T 16697—2017 replaces GB/T 16697—1996 and GB/T 12338—1990. The main technical content changes include:
- The name of the standard is changed to "General Technical Requirements and Measurement Methods for Television Cameras with Single Sensor Applications"
- The scope of application is expanded to cover analog, digital non-network and digital network cameras
- Environmental adaptability, electromagnetic compatibility and reliability requirements are added
- The measurement items and test conditions are adjusted, and new indicators such as eye diagram quality are introduced
2. Standard Framework Comparison Table
| Standard number | Scope of application | Main technical changes | Overview of revision content |
|---|---|---|---|
| GB/T 16697—2017 | Single sensor application television camera | Add environmental adaptability requirements | Modify measurement methods and test conditions |
| GB/T 16697—1996 | Black and white general purpose application television camera | Applicable only to analog signals | Does not include requirements for digital and network cameras |
| GB/T 12338—1990 | Measurement method for black and white general purpose application television camera | Safety and electromagnetic compatibility requirements are not included | The test conditions are relatively simple |
3. Interpretation of core technical requirements
6.4 Electrical performance requirements at room temperature is the core content of the standard, including:
- Brightness resolution and identification level: Table 1 clarifies the technical indicator requirements under different resolutions.
- CVBS video output technical requirements: Table 2 specifies the electrical performance parameters of analog cameras, including brightness sensitivity, signal-to-noise ratio, etc.
- YPBPR video output technical requirements: Table 3 lists the measurement indicators under HD and SD images in detail.
Case Study: Analog Camera CVBS Interface Test
For example, when testing the CVBS interface of an analog camera, a video analyzer is required to measure the brightness signal level (peak-to-peak) and the line/color burst signal level. The specific steps are as follows:
- Adjust the camera to the best focus state according to the standard test conditions.
- Use a grayscale ladder card as a test chart and ensure that the color temperature of the light source is 3100K ±100K.
- Use the video analyzer to select a line with a step change and measure the peak-to-peak value of the brightness signal level (e.g. 700±230 mV).
4. Implementation Suggestions
How can enterprises implement the requirements of GB/T 16697-2017:
- Product design stage: Strictly follow the technical requirements of the standard to design parameters to ensure that indicators such as brightness resolution and eye diagram quality are met.
- Test environment construction: Invest in high-precision instruments and equipment (such as video analyzers and oscilloscopes) to establish a darkroom test environment that meets the standards.
- Supply chain management: Select verified test cards and converters to ensure the consistency and reliability of measurement results.
