At present, the endoscope camera module is the preferred option for shooting in narrow environments. However, when choosing an endoscope camera module, it is not the case that the higher the resolution and clarity, the better. As a close-range imaging miniature camera module, multiple factors need to be comprehensively considered.
The core logic that resolution does not equal clarity
The limitation of pixel count
Oral clinical comparisons show that the difference in screen imaging clarity between 5-megapixel and 8-megapixel endoscopes is less than 5%, and the high pixel advantage is only prominent when printing in large formats.
In industrial scenarios, even with the same megapixel resolution, the imaging clarity can vary by up to 30%. The main reason for this lies in the different light transmittance and aberration control levels of optical lenses.
Sensor pixel size plays a crucial role
High-density pixel sensing enhances the low-light imaging capability by approximately 40% compared to conventional 1.4μm pixels at the same diameter by improving the efficiency of light capture.
Medical-grade sensors need to meet the requirements of tissue texture reproduction. A resolution of 400×400 combined with micro-pixel design can reach the micro-level recognition standard.
Ii. Multi-dimensional Factors Affecting Actual Clarity
1. Differences in optical lens requirements
Medical scenarios: For lenses with a diameter of less than 2mm, the distortion rate needs to be controlled at ≤8% to ensure the accurate restoration of tissue morphology
In industrial scenarios, an anti-vibration lens structure needs to be configured to withstand a vibration acceleration of ≥5G during pipeline inspection
2. Field of View selection logic
In the medical field, 120° wide-angle lenses are more often chosen: they need to be combined with edge resolution compensation algorithms to solve the problem of distortion in curved surface imaging
In the industrial field, 60° viewing Angle lenses are more often chosen: they can improve the local measurement accuracy to the 0.05mm level and are suitable for microcrack detection
3. Key parameters of lighting system
Medical lighting: It adopts 4500K±200 color temperature control to avoid thermal damage to biological tissues
Industrial lighting: It is necessary to achieve uniform supplementary lighting of over 200lux to solve the problem of light attenuation in deep cavity environments
4. Algorithm compensation mechanism comparison
Medical focus: Real-time noise reduction algorithms can reduce motion artifacts by 70%, and HDR fusion enhances vascular contrast
Industrial focus: The depth-of-field expansion algorithm extends the effective depth of field by 300%, solving the problem of blurred imaging at small focal lengths
Iii. Scenario-based Selection Guide
Minimally invasive surgery
The preferred combination is a diameter of 0.9-2mm and a resolution of 400×400. With micro-pixel technology, it ensures the recognition of organizational levels and avoids the decline in probe rigidity caused by blindly pursuing megapixels.
Industrial pipeline
It is necessary to balance the resolution and the field of view: for crack detection, a 60° narrow Angle +1080p resolution is used, while for corrosion scanning, a 120° wide Angle +720p resolution is selected.
Remote Diagnostics
Five million pixels are sufficient to meet the DICOM image transmission standard, while ultra-high pixels instead increase the risk of network latency.
Conclusion : Clarity is a systematic engineering of optical design, sensor performance and algorithm processing of . In the medical field, priority should be given to micro-trauma and biocompatibility. In the industrial field, dynamic adjustments need to be made based on defect size and spatial constraints.
