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(nèi)部成像元件出現(xiàn)故障。比如，在使用過程中，若不小心讓內(nèi)窺鏡接觸到油污等污染物，就會(huì)導(dǎo)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(huì)使圖像整體變得模糊，無法清晰顯示被檢測(cè)物體的細(xì)節(jié)。

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(qū)：出現(xiàn)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(diǎn)損壞。當(dāng)灰塵進(jìn)入內(nèi)窺鏡內(nèi)部并附著在鏡頭上時(shí)，會(huì)在圖像中形成黑斑；若傳感器的某些像素點(diǎn)因過熱、過電壓等原因損壞，也會(huì)導(dǎo)致相應(yīng)區(qū)域出現(xiàn)暗區(qū)，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(shè)置不當(dāng)，或者是光源系統(tǒng)出現(xiàn)問題。例如，在不同的光照環(huán)境下，如果沒有正確調(diào)整白平衡，圖像顏色就會(huì)出現(xiàn)偏差；而當(dāng)光源的發(fā)光強(qiáng)度不均勻、色溫發(fā)生變化，或者光源的濾光片損壞時(shí)，也會(huì)導(dǎo)致色彩失真，使被檢測(cè)物體的顏色與實(shí)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(nèi)部的鋼絲、彈簧等結(jié)構(gòu)損壞或變形，或者是外部受到擠壓、碰撞。比如，長(zhǎng)期頻繁使用可能導(dǎo)致鋼絲疲勞斷裂，使插入管失去柔韌性；而在存放或運(yùn)輸過程中，如果內(nèi)窺鏡受到外力撞擊，也會(huì)使插入管的結(jié)構(gòu)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(nèi)部電路故障、接觸不良，或者是機(jī)械結(jié)構(gòu)損壞。例如，頻繁按壓按鈕可能導(dǎo)致內(nèi)部的微動(dòng)開關(guān)損壞；而旋鈕的轉(zhuǎn)軸如果磨損，會(huì)使旋鈕無法正常轉(zhuǎn)動(dòng)，從而無法實(shí)現(xiàn)對(duì)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(jìn)或后退：可能是驅(qū)動(dòng)電機(jī)故障，或者是傳動(dòng)機(jī)構(gòu)出現(xiàn)問題，如齒輪磨損、皮帶松動(dòng)等。當(dāng)電機(jī)出現(xiàn)故障時(shí)，無法提供足夠的動(dòng)力來驅(qū)動(dòng)內(nèi)窺鏡的插入管前進(jìn)或后退；而傳動(dòng)機(jī)構(gòu)的部件磨損或松動(dòng)，使內(nèi)窺鏡在操作過程中出現(xiàn)卡頓或無法正常移動(dòng)的現(xiàn)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(tǒng)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(yīng)問題。燈泡在長(zhǎng)時(shí)間使用后，其發(fā)光效率會(huì)逐漸降低，導(dǎo)致亮度不足；另外，如果電源適配器故障，無法提供穩(wěn)定的電壓和電流，也會(huì)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(wěn)定：這可能是由于光源的驅(qū)動(dòng)電路故障，或者是燈泡的連接不良。驅(qū)動(dòng)電路中的電容損壞、芯片故障等，都可能導(dǎo)致光源的輸出不穩(wěn)定，出現(xiàn)閃爍現(xiàn)象；而燈泡與燈座之間如果接觸不良，在使用過程中也會(huì)因接觸電阻變化而導(dǎo)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.
