What is the typical FPS for endoscope cameras?

Introduction
When you look through an endoscope—for a medical procedure, industrial inspection, or plumbing check—the smoothness of the video matters. A choppy, laggy image makes it hard to see what you’re doing. That’s where frames per second (FPS) comes in. FPS measures how many images the camera captures and displays each second. Higher FPS means smoother motion, but it also needs more processing power and bandwidth. So what’s typical for endoscope cameras? And what FPS do you actually need? At Sincere, we’ve been manufacturing camera modules for over 30 years, including endoscope cameras for medical, industrial, and consumer use. This article explains typical FPS values and how to choose.

What Is FPS?
FPS stands for frames per second. It’s the number of individual images the camera captures every second. A 30 FPS video shows 30 images per second, which looks smooth to the human eye. Lower FPS, like 15 or 20, can appear jerky, especially when the camera or subject moves.

Typical FPS for Endoscope Cameras
Most standard endoscope cameras run at 30 FPS. This is the industry standard for smooth, real-time video.

Why 30 FPS Is Standard
30 FPS is the default for most endoscopes because:

• It provides smooth motion without noticeable lag.

• It balances image quality and data bandwidth.

• It’s compatible with most displays and recording systems.

• It doesn’t require excessive processing power.

A camera hd module (1080p) at 30 FPS is the most common configuration for professional endoscopes.

When Higher FPS Matters
Some applications need higher FPS:

• Medical surgery: 60 FPS helps capture fast movements like a beating heart or rapid instrument motion. But most surgical endoscopes run at 30 FPS—that’s sufficient for typical motion.

• Industrial inspection of moving parts: Inspecting a spinning turbine or fast conveyor belt? 60–120 FPS helps freeze motion without blur.

• High-speed documentation: Some 4k endoscope camera module models offer 60 FPS for ultra-smooth video.

When Lower FPS Is Acceptable
Lower FPS (15–20) may be fine for:

• Pipe inspection: The camera moves slowly; objects don’t move quickly.

• Basic presence/absence checks: You don’t need smooth motion to see a blockage.

• Low-bandwidth transmission: Dropping to 15 FPS saves bandwidth.

FPS and Resolution Trade-Off
Higher resolution needs more bandwidth, which can limit maximum FPS. For example:

• A 4k endoscope camera module (3840 × 2160) might run at 30 FPS maximum.

• The same sensor in 1080p mode could run at 60 FPS.

If you need both high resolution and high FPS, you’ll need a faster interface (USB 3.0 or MIPI) and more processing power.

FPS in Different Form Factors

USB Endoscope Cameras
Most borescope camera with light that connects via USB runs at 30 FPS. USB 2.0 modules max out at 30 FPS for 1080p. USB 3.0 can achieve 60 FPS at 1080p or 30 FPS at 4K.

Mini and Ultra-Mini Modules
An ultra mini camera module (under 2mm diameter) has a tiny sensor and limited bandwidth. These often run at 15–30 FPS due to physical constraints. The small sensor can’t read out pixels as quickly as a larger one.

Wireless Endoscopes
WiFi-based endoscopes often run at 20–30 FPS because wireless bandwidth is limited. Some drop to 15 FPS in poor signal.

Factors Affecting FPS

1. Sensor Readout Speed
A cmos module camera reads pixels row by row. Larger sensors with more pixels take longer to read. An ultra mini module with a small sensor may read out quickly, but its resolution is low.

2. Interface Bandwidth

• USB 2.0: ~40 MB/s. Enough for 1080p @ 30 FPS, not for 4K.

• USB 3.0: ~400 MB/s. Handles 4K @ 30 FPS or 1080p @ 60 FPS.

• MIPI CSI-2: High bandwidth, supports 4K @ 30–60 FPS.

• Analog (AHD/CVBS): Typically 30 FPS (NTSC) or 25 FPS (PAL).

3. Processor Power
The receiving device must process each frame. A slow processor may drop frames or add lag.

4. Lighting
In low light, the camera may need longer exposure, reducing effective FPS. Some cameras automatically lower FPS in dim conditions.

What FPS Do You Really Need?
For most endoscope applications, 30 FPS is sufficient and recommended.

Sincere’s Endoscope Modules
At Sincere, we manufacture endoscope cameras with various FPS options:

• Best camera module: Customizable FPS based on your application

• Borescope camera with light: 30 FPS standard for industrial borescopes

• Camera hd module: 1080p at 30 FPS or 60 FPS (USB 3.0)

• Cmos module camera: Sensors supporting 15–120 FPS

• 4k endoscope camera module: 4K at 30 FPS; 1080p at 60 FPS

• Ultra mini camera module: Typically 15–30 FPS due to size constraints

Our manufacturing includes Class 10/100 dust-free facilities and Active Alignment (AA) for perfect focus.

How to Choose

1. Assess motion speed: Slow movement = 30 FPS fine. Fast = 60+ FPS.

2. Consider resolution: Higher resolution may limit max FPS.

3. Check interface: USB 2.0 caps at 1080p 30 FPS; USB 3.0 or MIPI needed for higher.

4. Evaluate lighting: Low light may force lower FPS; ensure adequate illumination.

5. Test: A sample module can confirm whether 30 FPS meets your needs.

Summary
Typical FPS for endoscope cameras is 30 FPS. This provides smooth, real-time video for most medical, industrial, and consumer applications. Some specialized uses need 60 FPS or higher (fast motion, surgery), while basic pipe inspection can work at 15–20 FPS.

Factors affecting FPS include sensor readout speed, interface bandwidth, processor power, and lighting. An ultra mini camera module may be limited to 15–30 FPS. A 4k endoscope camera module typically runs at 30 FPS in 4K mode and 60 FPS in 1080p mode.
