圖像顯示異常

Abnormal image display

1、模糊不清：這是較為常見的問題，可能是由于鏡頭臟污、損壞，或者內部成像元件出現故障。比如，在使用過程中，若不小心讓內窺鏡接觸到油污等污染物，就會導致鏡頭模糊，影響觀察效果；而如果是成像芯片老化或損壞，也會使圖像整體變得模糊，無法清晰顯示被檢測物體的細節。

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、有黑斑或暗區：出現這種情況可能是鏡頭有遮擋物，如灰塵、異物等，或者是傳感器部分像素點損壞。當灰塵進入內窺鏡內部并附著在鏡頭上時，會在圖像中形成黑斑；若傳感器的某些像素點因過熱、過電壓等原因損壞，也會導致相應區域出現暗區，影響圖像的完整性。

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：可能是白平衡設置不當，或者是光源系統出現問題。例如，在不同的光照環境下，如果沒有正確調整白平衡，圖像顏色就會出現偏差；而當光源的發光強度不均勻、色溫發生變化，或者光源的濾光片損壞時，也會導致色彩失真，使被檢測物體的顏色與實際情況不符。

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、操控性異常

3. Abnormal handling

插入管彎曲困難：通常是由于插入管內部的鋼絲、彈簧等結構損壞或變形，或者是外部受到擠壓、碰撞。比如，長期頻繁使用可能導致鋼絲疲勞斷裂，使插入管失去柔韌性；而在存放或運輸過程中，如果內窺鏡受到外力撞擊，也會使插入管的結構受損，影響其彎曲性能。

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.

按鈕或旋鈕失靈：這可能是由于按鈕或旋鈕的內部電路故障、接觸不良，或者是機械結構損壞。例如，頻繁按壓按鈕可能導致內部的微動開關損壞；而旋鈕的轉軸如果磨損，會使旋鈕無法正常轉動，從而無法實現對焦、變焦等功能。

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、無法正常推進或后退：可能是驅動電機故障，或者是傳動機構出現問題，如齒輪磨損、皮帶松動等。當電機出現故障時，無法提供足夠的動力來驅動內窺鏡的插入管前進或后退；而傳動機構的部件磨損或松動，使內窺鏡在操作過程中出現卡頓或無法正常移動的現象。

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、光源系統異常

5. Abnormal light source system

亮度不足：可能是燈泡老化、損壞，或者是電源供應問題。燈泡在長時間使用后，其發光效率會逐漸降低，導致亮度不足；另外，如果電源適配器故障，無法提供穩定的電壓和電流，也會影響光源的亮度。

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、閃爍或不穩定：這可能是由于光源的驅動電路故障，或者是燈泡的連接不良。驅動電路中的電容損壞、芯片故障等，都可能導致光源的輸出不穩定，出現閃爍現象；而燈泡與燈座之間如果接觸不良，在使用過程中也會因接觸電阻變化而導致光源閃爍。

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.
