When buyers compare camera modules for embedded vision, robotics, industrial devices, or custom OEM projects, two Sony sensor names come up often: IMX219 and IMX477. A common question is simple: what is the difference between IMX219 and IMX477 camera modules?
The short answer is this: IMX219 camera modules are usually chosen for compact 8MP designs, while IMX477 camera modules are typically selected when the project needs a larger sensor, 12MP resolution, and more flexibility in lens choice. In widely used reference products, the Sony IMX219 is used in Raspberry Pi Camera Module 2 at 3280 × 2464 resolution, while the Sony IMX477 is used in the Raspberry Pi High Quality Camera at 4056 × 3040 resolution.
That already tells you the biggest practical difference: an IMX219-based module is generally positioned as an 8MP Camera Module, while an IMX477-based design is generally positioned as a 12MP Camera Module. But resolution is only part of the story. Sensor size, lens support, and project goals matter just as much.
IMX219 vs IMX477: the basic sensor difference
The Sony IMX219 is an 8.08-megapixel sensor with a Type 1/4.0 optical format. The Sony IMX477 is a 12.3-megapixel sensor with a larger Type 1/2.3 optical format. Sony's IMX477 flyer also describes it as a stacked CMOS image sensor, while Raspberry Pi's High Quality Camera brief describes the module as using a 7.9 mm diagonal sensor.
In plain language, that means IMX477 is not just a higher-resolution sensor than IMX219; it is also physically larger. That larger format gives module designers more room to work with when the project needs better image quality expectations, better lens options, or a more "camera-like" module design rather than a very small fixed-lens board. That is one reason IMX477-based products are often used in "HQ" camera designs.
Resolution: 8MP vs 12MP
If you compare the two at the most basic level, IMX219 is the lower-resolution option and IMX477 is the higher-resolution option.
The Raspberry Pi Camera Module 2 page states that the Sony IMX219 sensor is 8 megapixels, and the documentation lists a resolution of 3280 × 2464. Raspberry Pi's High Quality Camera documentation states that the Sony IMX477 sensor is 12 megapixels with a resolution of 4056 × 3040. Sony's own IMX477 flyer lists it as 12.3 megapixels.
For OEM buyers, the practical takeaway is straightforward:
- choose IMX219 when an 8MP Camera Module is enough for the application
- consider IMX477 when the project benefits from a 12MP Camera Module with more image detail or more room for cropping and framing during processing
That said, more megapixels do not automatically mean a better final image. Lens quality, ISP tuning, working distance, and lighting still matter.
Sensor size and low-light expectations
A major difference between these two sensors is optical format. The Sony IMX219 is Type 1/4.0, while the Sony IMX477 is Type 1/2.3. Raspberry Pi's High Quality Camera brief explicitly links the IMX477-based camera's 7.9 mm diagonal sensor to better low-light potential.
This is important because many buyers compare IMX219 and IMX477 only by megapixels. In practice, the larger sensor format of Sony IMX477 is one of the main reasons developers choose it. If a project needs more image flexibility, improved low-light expectations, or better use of interchangeable lenses, IMX477 usually has the stronger starting point. If the project is more space-sensitive and does not need that larger optical format, Sony IMX219 can still be a very practical choice.
Lens and module design: one of the biggest real-world differences
This is where the difference between modules becomes especially clear.
In one of the most widely used IMX219 reference products, Raspberry Pi Camera Module 2 is built around a compact camera board. By contrast, Raspberry Pi's High Quality Camera built around IMX477 is specifically designed to accept CS-mount lenses, and with an adapter it can also use C-mount lenses. Raspberry Pi also offers an M12-mount version of the High Quality Camera.
That means the question is not only IMX219 vs IMX477 at the sensor level. It is also about what kind of module ecosystem you want.
- A typical Sony Camera Module based on IMX219 is often smaller and more straightforward.
- A typical Sony Camera Module based on IMX477 is often better suited to projects that need more lens flexibility and more serious optical customization.
For OEM development, that difference can matter more than the megapixel number alone.
Are IMX219 and IMX477 both rolling shutter?
Yes. Public module and sensor references for both families identify them as rolling shutter sensors. Arducam's IMX219 specifications list rolling shutter for IMX219-based modules, and IMX477 reference specifications likewise describe IMX477 as a rolling shutter color sensor.
This matters because some buyers assume IMX477 is a step up in every direction, including shutter type. It is not. If your application specifically needs motion-free capture for industrial measurement or fast-moving targets, the bigger decision may not be IMX219 vs IMX477, but rather whether you need a global shutter sensor instead of either of them.
When IMX219 makes more sense
An IMX219-based module often makes more sense when the project needs:
- a compact 8MP Camera Module
- a simpler embedded camera design
- a familiar CSI/MIPI camera path
- enough resolution for standard robotics, smart devices, or general embedded vision use
This is why Sony IMX219 remains popular in Raspberry Pi and embedded ecosystems. It gives developers an accessible Sony Camera Module option without moving into a larger-format, more optics-heavy design.
When IMX477 makes more sense
An IMX477-based module usually makes more sense when the project needs:
- a 12MP Camera Module
- a larger sensor format
- interchangeable lens options
- more flexibility for image framing, optical tuning, or higher-end embedded imaging
In other words, Sony IMX477 is often the better fit when the camera module is part of a more advanced optical system rather than a basic compact board camera. That is exactly how Raspberry Pi positions its High Quality Camera platform.
Which one is better for OEM projects?
The honest answer is: neither is universally better.
A Sony IMX219 module is often better when the goal is a compact, practical 8MP Camera Module for embedded integration. A Sony IMX477 module is often better when the goal is a larger-format 12MP Camera Module with more lens flexibility and higher image-detail potential.
For OEM buyers, the better selection process is:
- define the resolution target
- define the lens and field-of-view requirements
- define whether the product needs a very compact module or a more flexible optical platform
- then compare IMX219 and IMX477 module designs that fit those constraints
That approach is much more useful than choosing by sensor name alone.
