Introduction
A gastroscope is a medical device used to examine the stomach and upper digestive tract. It is a type of endoscope that goes through the mouth and down the esophagus. The camera at the tip is one of the most critical components – it must be small enough to fit through narrow passages, yet deliver high‑quality images for accurate diagnosis. This article explores the camera technology used in gastroscopes, including resolution, sensor type, and key design requirements. At Sincere, we have manufactured cmos module camera solutions for over 30 years, including medical endoscope camera modules for gastrointestinal applications.
What Is a Gastroscope Camera?
A gastroscope camera is a miniature Endoscope Camera Module at the distal tip of the flexible tube. It captures real‑time video of the esophagus, stomach, and duodenum. The camera must be:
Very small (5–10mm diameter) to pass through the mouth.
Highly sensitive to work with limited illumination.
Sterilizable (or part of a single‑use disposable scope).
Color accurate to help doctors identify abnormalities.
Key Components
Image Sensor – Almost all modern gastroscopes use a cmos module camera. CMOS offers low power (less heat), high sensitivity, and small size. Common sensors: Sony IMX290/IMX307 (1080p), IMX415 (4K).
Lens – Wide‑angle (90°–140°), fixed focus. A wide view lets the doctor see more of the stomach wall without moving the scope. Glass or medical‑grade optical material that withstands sterilization.
Illumination – Fiber optic light guides or built‑in LEDs. High sensor sensitivity is essential.
Cable – Video signal travels through the flexible cable to a camera control unit (CCU). Interfaces: analog (NTSC/PAL) or digital (MIPI, LVDS).
Resolution: 1080p vs. 4K
Resolution | Use in Gastroscopy |
|---|---|
720p | Older systems; still usable |
1080p | Current standard – enough for fine mucosal patterns |
4K | High‑end – reveals very fine details for early cancer detection |
A 4k endoscope camera module provides four times the detail of 1080p. For gastroscopy, 4K helps identify subtle lesions. However, 1080p remains most common because it balances quality, cost, and bandwidth.
Medical Requirements
Requirement | Why It Matters |
|---|---|
Small diameter | Fits through mouth and esophagus (5–10mm) |
High sensitivity | Works with limited light inside the stomach |
Accurate color | Distinguishes healthy from abnormal tissue |
Sterilization | Withstands autoclave or chemical sterilization |
Low heat | CMOS generates less heat – safer for patient |
High frame rate | 30fps or 60fps for smooth video |
OEM Endoscope Camera Module for Gastroscopes
Medical device companies use OEM Camera Module services for custom gastroscope cameras. A typical OEM Camera Module project includes:
Custom diameter (e.g., 5.2mm or 7.5mm) to fit the scope tip.
Specific lens (FOV, depth of field) for gastric anatomy.
Sensor choice (1080p or 4K).
Sealing for sterilization.
Cable and connector to match the CCU.
Sincere provides OEM Camera Module for medical endoscopy, including gastroscope cameras.
USB Endoscope Camera Module in Gastroscopy?
While usb endoscope camera module devices are common for industrial inspection, they are rarely used in clinical gastroscopy. Medical gastroscopes require medical‑grade sterilization, certified electronics, and low latency. USB modules are more common in training simulators or low‑cost veterinary scopes.
Single‑Use (Disposable) Gastroscope Cameras
Single‑use gastroscopes are becoming more popular to eliminate infection risk. They contain a medical endoscope camera modules designed for one procedure. The camera is typically lower cost (720p or 1080p) using a cmos module camera to keep power and heat low.
Sincere’s Gastroscope Camera Modules
At Sincere, we design and manufacture medical endoscope camera modules for gastrointestinal applications:
OEM Camera Module – Custom gastroscope cameras for your diameter, resolution, sterilization.
4k endoscope camera module – 4K sensors for advanced lesion detection.
Usb endoscope camera module – For training or veterinary gastroscopes (non‑sterile).
Endoscope Camera Module – Complete assembly with lens, sensor, cable.
Medical endoscope camera modules – Certified for medical use (FDA, CE on request).
Cmos module camera – Sony IMX290/IMX307 (1080p), IMX415 (4K).
Summary
The camera in a gastroscope is a miniature Endoscope Camera Module based on a cmos module camera sensor. It must be small, sensitive, and color‑accurate. Current standard: 1080p; 4K is emerging for high‑end systems. The camera works with fiber optic illumination and a flexible cable. For medical device manufacturers, OEM Camera Module services provide custom gastroscope cameras. While usb endoscope camera module devices are not used in clinical gastroscopy, they serve training and veterinary markets.
