图像显示异常

Abnormal image display

1、模糊不清：这是较为常见的问题，可能是由于镜头脏污、损坏，或者内部成像元件出现故障。比如，在使用过程中，若不小心让内窥镜接触到油污等污染物，就会导致镜头模糊，影响观察效果；而如果是成像芯片老化或损坏，也会使图像整体变得模糊，无法清晰显示被检测物体的细节。

1. Blurriness: This is a common issue, which may be due to dirty or damaged lenses, or internal imaging components malfunctioning. For example, during use, if the endoscope accidentally comes into contact with pollutants such as oil stains, it can cause the lens to blur and affect the observation effect; If the imaging chip ages or is damaged, it will also make the overall image blurry, making it difficult to clearly display the details of the detected object.

2、有黑斑或暗区：出现这种情况可能是镜头有遮挡物，如灰尘、异物等，或者是传感器部分像素点损坏。当灰尘进入内窥镜内部并附着在镜头上时，会在图像中形成黑斑；若传感器的某些像素点因过热、过电压等原因损坏，也会导致相应区域出现暗区，影响图像的完整性。

2. There are black spots or dark areas: This situation may be due to obstructions in the lens, such as dust, foreign objects, or damaged pixels in the sensor. When dust enters the endoscope and adheres to the lens, it forms black spots in the image; If some pixels of the sensor are damaged due to overheating, overvoltage, or other reasons, it will also cause dark areas in the corresponding areas, affecting the integrity of the image.

色彩失真：可能是白平衡设置不当，或者是光源系统出现问题。例如，在不同的光照环境下，如果没有正确调整白平衡，图像颜色就会出现偏差；而当光源的发光强度不均匀、色温发生变化，或者光源的滤光片损坏时，也会导致色彩失真，使被检测物体的颜色与实际情况不符。

Color distortion: It may be due to improper white balance settings or issues with the lighting system. For example, in different lighting environments, if the white balance is not adjusted correctly, the color of the image will deviate; When the luminous intensity of the light source is uneven, the color temperature changes, or the filter of the light source is damaged, it can also cause color distortion, resulting in the color of the detected object not matching the actual situation.

3、操控性异常

3. Abnormal handling

插入管弯曲困难：通常是由于插入管内部的钢丝、弹簧等结构损坏或变形，或者是外部受到挤压、碰撞。比如，长期频繁使用可能导致钢丝疲劳断裂，使插入管失去柔韧性；而在存放或运输过程中，如果内窥镜受到外力撞击，也会使插入管的结构受损，影响其弯曲性能。

Difficulty in bending the insertion tube: usually due to damage or deformation of the steel wires, springs, and other structures inside the insertion tube, or external compression or collision. For example, long-term and frequent use may lead to fatigue fracture of the steel wire, causing the insertion tube to lose its flexibility; During storage or transportation, if the endoscope is impacted by external forces, it can also damage the structure of the insertion tube, affecting its bending performance.

按钮或旋钮失灵：这可能是由于按钮或旋钮的内部电路故障、接触不良，或者是机械结构损坏。例如，频繁按压按钮可能导致内部的微动开关损坏；而旋钮的转轴如果磨损，会使旋钮无法正常转动，从而无法实现对焦、变焦等功能。

Button or knob malfunction: This may be due to internal circuit failure, poor contact, or mechanical structural damage of the button or knob. For example, frequent button presses may cause damage to the internal micro switch; If the rotating shaft of the knob is worn, it will prevent the knob from rotating normally, thus making it impossible to achieve functions such as focusing and zooming.

4、无法正常推进或后退：可能是驱动电机故障，或者是传动机构出现问题，如齿轮磨损、皮带松动等。当电机出现故障时，无法提供足够的动力来驱动内窥镜的插入管前进或后退；而传动机构的部件磨损或松动，使内窥镜在操作过程中出现卡顿或无法正常移动的现象。

4. Unable to advance or retract normally: It may be due to a malfunction in the drive motor or a problem with the transmission mechanism, such as worn gears, loose belts, etc. When the motor malfunctions, it cannot provide sufficient power to drive the insertion tube of the endoscope forward or backward; And the wear or looseness of the transmission mechanism components can cause the endoscope to jam or fail to move normally during operation.

5、光源系统异常

5. Abnormal light source system

亮度不足：可能是灯泡老化、损坏，或者是电源供应问题。灯泡在长时间使用后，其发光效率会逐渐降低，导致亮度不足；另外，如果电源适配器故障，无法提供稳定的电压和电流，也会影响光源的亮度。

Insufficient brightness: It may be due to aging or damaged light bulbs, or power supply issues. After prolonged use, the luminous efficiency of light bulbs will gradually decrease, resulting in insufficient brightness; In addition, if the power adapter malfunctions and cannot provide stable voltage and current, it will also affect the brightness of the light source.

6、闪烁或不稳定：这可能是由于光源的驱动电路故障，或者是灯泡的连接不良。驱动电路中的电容损坏、芯片故障等，都可能导致光源的输出不稳定，出现闪烁现象；而灯泡与灯座之间如果接触不良，在使用过程中也会因接触电阻变化而导致光源闪烁。

6. Blinking or instability: This may be due to a malfunction in the driving circuit of the light source, or a poor connection of the light bulb. Damage to capacitors and chip failures in the driving circuit can lead to unstable output of the light source, resulting in flickering; If there is poor contact between the light bulb and the lamp holder, the light source may flicker due to changes in contact resistance during use.
