A fourth-generation global-shutter sensor is a back-illuminated CMOS design that lets more light reach the photodiode while keeping the pixels small. Sony’s Pregius S implementation uses 2.74 µm pixels. That architecture can support compact, high-resolution, fast cameras, but megapixels alone do not tell you whether a sensor will capture a faint feature, freeze motion, fit your lens or move images fast enough for an embedded system.
What global shutter does—and what it does not do
A global shutter exposes the image sensor’s pixels at the same time, then reads out the captured image. A rolling shutter instead scans rows sequentially. If an object moves during that scan, different parts of it can be recorded at different moments, distorting its apparent shape or position. Global capture avoids that row-by-row timing distortion: Sony describes the approach as capturing the entire object before output.
Global shutter does not, by itself, guarantee a sharp image or high throughput. The exposure still has to be short enough to limit motion blur, and the camera must read and transmit the image at a rate the rest of the system can handle. A global shutter addresses when pixels capture the scene; exposure duration, readout, interface and processing determine other parts of the imaging result.
What “fourth generation” means
Here, “fourth generation” refers to a particular progression in global-shutter CMOS technology, not a universal industry standard that every sensor maker uses. The generational labels describe changes in pixel architecture and sensor functions; they are useful context, but a real selection should be made from a specific sensor or camera’s specifications.

| Generation in this progression | Reported architecture or capability | What changed |
|---|---|---|
| First | About 2.4 MP; 5.86 µm pixels; multi-frame region of interest (ROI) | Introduced global shutter and multi-frame ROI. |
| Second | 3.45 µm pixels; approximately 0.4–31 MP across the described range; minimum exposure reduced to 2 µs | Added multi-exposure triggers and shorter minimum exposure. |
| Third | 4.5 µm pixels | Added dual ADC, dual trigger, on-sensor conversion gain and self-trigger functions; the larger pixel size improved saturation capacity alongside dynamic range and speed. |
| Fourth | Back-illuminated structure; 2.74 µm Pregius S pixels | Reverses the relative placement of wiring and photodiode layers so light reaches the photosensitive layer with less obstruction. The described design reduces pixel size to about 63% of the conventional front-illuminated size without reducing saturation characteristics. |
The fourth-generation change is not simply “smaller pixels.” In Sony’s Pregius S explanation, back illumination makes smaller pixels possible while maintaining imaging performance, and stacked construction provides additional area for signal processing and functions. Sony’s industrial lineup lists Pregius S families at 2.74 µm pixel pitch.
Why megapixels are not enough for embedded imaging
Megapixels tell you how many samples an image contains. They do not establish whether the system can detect the feature you care about under its lighting, motion, lens, bandwidth and power constraints. Compare the following performance axes rather than selecting by resolution alone.
Light sensitivity and quantum efficiency
Quantum efficiency (QE) is the proportion of incoming photons converted into signal. Teledyne reports 71.5% QE for the IMX530 and IMX540 Pregius S sensors, compared with 65% for earlier global-shutter generations. A higher QE can help capture a usable signal with less illumination or a shorter exposure, though the outcome also depends on the scene, optics, sensor settings and noise.

Saturation capacity and dynamic range
Saturation capacity describes how much signal a pixel can hold before it clips. Dynamic range concerns the span between distinguishable dark signals and the brightest signals a sensor can record. Smaller pixels generally collect fewer photons unless the pixel structure and photodiode compensate. The described third-generation 4.5 µm design increased pixel size to recover saturation capacity while improving dynamic range and speed. Compare the specified sensor’s actual saturation and dynamic-range figures under relevant operating modes; pixel pitch alone cannot settle the question.

Read noise affects how clearly a weak signal can be distinguished from noise introduced when the sensor’s signal is read. Sony’s Pregius architecture uses parallel conversion and a memory section to preserve simultaneous capture while supporting low-noise processing. A Sony prototype announcement in 2018 reported 5.15 electrons RMS in low-noise mode. That is a historical prototype result, not a specification to assume for every Pregius sensor or current camera.
Exposure, frame rate and end-to-end throughput
Exposure time sets how long light accumulates for each image; frame rate describes how often images can be produced. Readout and data transport add further throughput constraints. A camera that captures a frame globally can still blur a fast object if exposure is too long, or fail to keep up if its readout and output path cannot sustain the required rate. Check exposure limits, achievable frame rates at the chosen resolution and bit depth, trigger behavior, and the camera-to-host data path together.

ADC design and power
An analog-to-digital converter (ADC) turns a pixel’s analog signal into digital data. ADC arrangement can affect speed, noise, power and sensor complexity. In a 2018 announcement, Sony reported a pixel-parallel prototype with roughly one ADC per pixel, a compact 14-bit converter, 654–746 mW power, 660 fps, and an ADC figure of merit of 0.24 e⁻·nJ/step. These are prototype figures from that announcement, not general performance claims for current sensors. For an embedded product, assess the complete camera and processing chain’s power and thermal limits, not only sensor-level figures.
Interface bandwidth and host processing
Resolution, bit depth and frame rate determine how much image data must move, while the interface and host determine whether that data can be delivered and processed in time. Sony positions Pregius S with flexible back-illuminated wiring and SLVS-EC, an embedded-clock signaling interface, for high-speed output. Match the camera’s interface and output modes to the host’s available connections, bandwidth and processing capacity; a fast sensor cannot overcome a bottleneck downstream.
Optics, sensor size and integration
Pixel pitch is only one part of lens compatibility. Sensor size, lens image circle, shading and chief-ray angle—the angle at which light reaches the sensor—also matter. Sony positions Pregius S for compact C-mount systems and gives a 1.2-type example reaching 24.45 MP. Confirm the actual camera’s sensor format and lens compatibility rather than assuming that a small pixel pitch guarantees a compact or optically suitable system.

Examples: sensor families and complete cameras
Sensor specifications describe imaging components; complete camera examples show how a sensor is paired with an interface and a practical output rate. The figures below are the specific models and examples identified by Sony and Teledyne, not guarantees for every configuration or operating mode.
| Product or family | Pixel pitch | Resolution or range | Interface or rate stated |
|---|---|---|---|
| Sony 2.7 Series (Pregius S) | 2.74 µm | 5.1–24.5 MP | Not stated in the cited lineup description. |
| Sony 2.7 UHS Series | 2.74 µm | Products extend to 105 MP | Not stated in the cited lineup description. |
| Teledyne Blackfly S USB3 with Sony IMX540 | Not stated for this camera example | 24.5 MP | USB3; 15 fps |
| Teledyne Oryx 10GigE with Sony IMX530 | Not stated for this camera example | 24.6 MP | 10GigE; 35 fps |
| Teledyne Blackfly S GigE with Sony IMX542 | Not stated for this camera example | 16.1 MP | GigE; 7 fps |
The camera examples make a practical point: equal emphasis on resolution can hide substantial differences in interface and stated frame rate. Those rates do not by themselves establish exposure time, image quality, host compatibility or sustained performance in a particular installation.
How to choose a global-shutter camera for high-speed machine vision
Start with the imaging task and the system limits, then check the candidate camera’s datasheet and operating modes. This sequence helps avoid selecting a high-resolution sensor that cannot meet the actual motion, light or integration requirement.
- Define the measurement. Specify the smallest feature that must be detected, the field of view, and how much position or shape error is acceptable. This determines useful resolution more directly than choosing the largest megapixel count.
- Set motion and timing requirements. Establish the object speed, trigger timing and maximum exposure that will limit blur. Verify global exposure and trigger behavior for the exact camera, not merely the sensor family.
- Check the light budget. Compare QE, read noise, saturation capacity and dynamic range alongside available illumination. A higher QE can help, but does not replace checking whether highlights clip or weak features disappear under real conditions.
- Calculate the data path. Check the intended resolution, bit depth and frame rate against the camera interface and host’s ability to receive, store and process frames. Include readout and transfer constraints in addition to exposure.
- Verify physical and electrical integration. Confirm sensor format, lens coverage, C-mount or other lens fit, shading and chief-ray-angle suitability, as applicable. Check camera, interface and processing power and thermal limits for the intended enclosure.
- Use embedded features only when they solve a defined problem. ROI can reduce the image area to process; multi-exposure triggers, dual ADC, self-trigger or on-sensor processing may support specific timing or processing needs. Confirm which functions are available on the chosen model and whether using them changes image modes or performance.
For a first comparison, organize candidate specifications under five headings: motion fidelity and triggering; light performance; throughput; optical and electrical integration; and embedded functions. This exposes trade-offs that a megapixel-only shortlist conceals.
What the fourth generation changes—and what it cannot decide for you
Back illumination gives the fourth-generation design a way to combine smaller pixels with strong light collection, and Sony’s Pregius S examples span compact, multi-megapixel sensors through high-resolution products. That makes the architecture relevant to embedded machine vision where size, speed and optical constraints interact. It does not make a sensor automatically superior for every task: exposure, noise, saturation, interface throughput, lens fit and power still have to match the application.
