Shiningintl Endoscope Camera Module Solution


In the field of medicine, endoscope camera technology is a revolutionary innovation that allows doctors to observe and treat the human body’s interior without open surgery. The principles and applications of endoscope camera obey multiple disciplines, from basic physical optics to advanced digital imaging technology, and its development has greatly propelled the advancement of minimally invasive surgery. In this article will discuss in detail the working principles of  smochm endoscope camera solution, their design features, and their applications in multiple areas such as medicine, industries.

1.Basic structure of Endoscope camera

The core principle of endoscope is to utilize the transmission and reflection characteristics of light, through a series of optical components, to convey images of the human body’s interior to the outside for medical observation and other purpose. This process involves several key steps:

1.1 lighting system for camera:

An endoscope contains an internal light source, usually LEDs or halogen lamps transmitted via fiber optics, which provide necessary illumination to light up dark areas inside the body, making internal tissues visible.

1.2 Imaging sensor system:

The top of the endoscope is equipped with a set of lens systems that can focus and magnify the image of internal tissues. Depending on the design and requirements, an endoscope can be fitted with a single lens, double lenses, or a complex zoom system. there is a digital camera sensor behind the lens to remap the real world to digital world.

1.3 lighting and sensor control system

In order to control the lighting system and the imaging sensor system, there is a control board behind the lighting system and the image sensors, normally the camera sensor connect to the control system board with the MIPI CSI interface, the control system can adjust the lighting strength and the camera sensors parameters, or process the datas from the camera sensors, and then conveying to next stage.

1.4 Transmission unit of video and image :

After imaging, the image and video datas are transfer to control system board , at this stage , we will transfer the data with a common interface- USB interface, the USB interface is a popular driver free interface for many devices, such as computer, mobile phone, with the USB interface, the captured video and image are easy to hand over to the powerful display device and data analysis device, for more convenient to the other end of the endoscope. During this process, the optical signal may be enhanced or processed to improve image quality.

smochm also provide wireless transmission solution additional to the USB connection, with smochm wifi transmission board, the USB input data can be sent out with wifi signal , then the communication between the endoscope modue and display system or analysis unit can be seperated.

1.5 endoscope camera central processing unit:

Finally, the optical signal is converted into an electrical signal and captured by a camera or other sensors, transmitted to a display screen, allowing doctors to observe the internal conditions in real-time through a monitor.

 

2.Design Features of smochm Endoscope camera solution

To meet various applications, endoscopes are designed with multiple features, normally there are two types of endoscope in smochm solution: integrated endoscope camera and seperated endoscope camera.

integrated endoscope camera: the camera sensors ,lighting unit , control unit and transmission unit are integrated into 1 motherboard. the features: smaller size, but higher temperature.

seperated endoscope camera: the camera sensor and lighting unit are seperated with other units. the features: can get lower temperature ,but has bigger size.

2.1 Combination of Flexibility and Rigidity:

Endoscopes often have soft and bendable probes and sturdy outer tubes, allowing them to easily navigate through the body’s winding passages while maintaining stable image quality.

2.2 Multifunctional Channels:

Many endoscopes are designed with working channels that allow doctors to perform biopsies, tissue removal, or other therapeutic procedures through the scope.

2.3 High-Definition Imaging:

With technological advancements, the imaging capability of endoscopes continues to improve, with some high-end models even capable of providing three-dimensional images, significantly enhancing diagnostic accuracy. normally in medicine area, the medical endoscope needs a small size, the sensor pixels is from 0.08M to 1M pixels, the 2M and above pixels sensor are used in industrial purpose for its size bigger.

2.4 small and precise design

the smochm endoscope solution can provide small size to meet requirements from our clients, we can provide small size camera lens from 1.2mm to 9mm size to meet different applications.

3.important parameters of Endoscope camera

What are the important parameters for an endoscope camera? for medical small size endoscopes, there are some key parameters that need to be paid attention to:
the important parameters for endoscope camera

Light intensity.

The light intensity is crucial for the image quality of endoscopes, as the working environment of medical endoscopes often lacks sufficient light and requires the lens itself to have a certain level of light intensity. but at the another size, the lighting brightness can’t be too strong, because the body can’t resist a high temperature, for example , the nose endoscope and otoscope can’t have too strong lighting, the high temperature may hurt the tissues and make the patients unconfortable. it is very important t balance the temperature and the light intensity. smochm medical endoscope solution will control the temperature lower 40 celsius degree. it is similar to the body temperature. There are 4 LED lights to 10 LED lights in the lens depending on the endoscope purpose.

Focal length.

Focal length can affect the range of lens observation. If it is too far away, it will not be able to see the area clearly, and if it is too close, it will not be able to see the entire area. smochm medical endoscope camera solution normally controls the focal length from 5mm to 100mm, but please bear in mind that the shorter of the focal length, the more difficult it will be, and the cost will be higher.

Resolution.

Resolution can affect the clarity of an image, usually expressed in lines/millimeters or pixels/millimeters. The clarity of the endoscope lens is crucial as it affects the final examination results and the doctor’s judgment. as the small size requirement, we can’t put in big sensors intu the lens, the smaller the size is, the more expensive it is, normally 1M pixels camera is enough for medical endoscope, for 1.2mm or 1.5mm endoscope, the size is very small, we have to use the 0.16M pixels camera sensor.

Field of view angle.

Field of view angle, which refers to the range of field of view that the lens can cover, is generally expressed in terms of angle and is one of the important parameters of the lens, the bigger of the view angle, the more expensive it is.

In the space sector, endoscopes are used for quality control during the research, development, manufacturing, and assembly of rocket engines, as well as for defect investigation in critical parts such as flight navigation systems.

Rail transportation field:

With the development of high-speed railways, endoscopes are also used for inspections of foreign high-speed railways and domestic CRH models.

Metal workpieces and non-metallic products:

Endoscopes can be used to detect defects such as burrs, scale, and residues inside metal workpieces, and defects like black spots on the inner surface of ceramic blanks, uneven glaze layers, and bubbles in non-metallic products.

Special equipment:

For the inspection of special equipment such as pipelines, endoscopes can check for new defects in abnormal parts of pipeline structures and geometric sizes. In summary, the application of endoscopes in industry is very extensive, covering multiple fields from aerospace to automobile manufacturing, electricity, petrochemicals, etc., meeting the exploration needs of hidden parts within equipment, ensuring the safe operation of equipment and the control of product quality.
