Contemporary coverage described the move as a “bypass” of MIPI because MIPI’s camera-interface work had not yet produced a result. Nokia, however, called SMIA complementary to MIPI’s effort. SMIA covered more than a data link: it also addressed module mechanics, electrical and functional interfaces, software, reliability, and characterization.
What was SMIA?
SMIA stands for Standard Mobile Imaging Architecture. Nokia and STMicroelectronics announced it as a common specification intended to make mobile camera modules easier to design and source from multiple suppliers. The announcement said the specification was offered free to the mobile imaging industry. A contemporaneous report said the companies held key patents and other intellectual property while intending to open the specification to developers; the available accounts do not establish its present-day licensing or maintenance status.
The standard treated the camera module as a broader component, not merely a serial connection between an image sensor and a host. Its described coverage included electrical, mechanical, and functional interfaces, along with optical performance, characterization, reliability, and software. A contemporary report organized the material into six chapters: electrical, functional, mechanical, characterization, reliability, and software.
What the specification covered
- Electrical: physical layer, voltage levels, pin count, timing, electromagnetic interference, and output image format.
- Mechanical: socketable module design and module-size outlines.
- Functional and image data: module behavior and output in Raw Bayer Data, which could be reconstructed by a host processor or a separate image processor.
- Characterization, optics, and reliability: provisions for describing and assessing module performance and reliability.
- Software: a camera-module software model and reference driver architecture.
The 2004 description left vendors choices including optics, optical performance, resolution, and internal structure. EE Times reported three SMIA 1.0 module outlines—6.5 × 6.5 mm, 8.5 × 8.5 mm, and 9.5 × 9.5 mm—with two height options for each. Those are historical format details, not evidence that the same sizes remain commonly available.

Why did Nokia and ST “bypass” MIPI?
“Bypass” was the contemporary press framing of a parallel initiative, not the name of a formal dispute or proof that SMIA and MIPI were incompatible. Nokia and ST were reported to be MIPI founding members. They said they pursued SMIA on an accelerated schedule because they saw an immediate need for a camera-module standard while MIPI’s broader camera and display interface work was still under way.
In the 2004 EE Times account, Nokia’s Janne Haavisto, director of Camera Entity at Nokia Technology Platforms, described MIPI’s work as “a long-term, on-going activity” that had produced “no outcome yet.” He characterized SMIA as complementary to MIPI’s work. ST marketing director Philippe Quinio said, “We need to make a choice on a camera interface now for higher resolution camera phones coming out in 2005.” These statements explain the timing as the companies presented it; they do not establish that SMIA became a MIPI specification.

- 【Compliance And Safety】FCC/CE/UKCA certified, RoHS & REACH-SVHC compliant, tested by accredited labs.
The companies’ stated practical aim was to reduce duplicated interface and module-design work and make multiple sourcing easier. Haavisto said the standard would enable multiple sourcing of camera modules and help buyers “compare apples to apples.” These were launch-era goals, not measured evidence of later adoption or market impact.
What did SMIA’s camera interface use?
SMIA’s high-speed serial link was based on Compact Camera Port 2 (CCP2). In 2004, EE Times reported a maximum bandwidth of up to 650 Mbit/s for CCP2 and cited up to 208 Mbit/s for a then-current CCP1 example. Both figures describe the historical interfaces as reported at that time; neither is a current MIPI CSI-2 performance figure.

- 【Wide Range of Applications】: It can be applied to face recognition, license plate recognition, drone aerial photography, high-definition cameras, QR code gates, robot vision and many other industry products
- 【Strong Compatibility】: Supports WinXP/Win7/Win8/Win10/Linux/MAC/Android and more. Support OTG UVC USB interface, drive-free, plug and use
- 【Stable Performance】 The USB Camera Module is equipped with a high‑definition photosensitive chip ov9732 for stable performance and clearer images
- 【Adjustable Focal Length】100-degree field of view, larger viewing range, more open field of view, can be adjusted by rotating the lens shooting focus
- 【Package Included】: 3 X 100 Degrees OV9732 Camera Module, 3 X 2m USB Cable
That distinction matters because SMIA’s scope extended beyond the serial link. Its module geometry and software provisions were part of the broader architecture, while CCP2 described the link used to carry image data.
How does SMIA differ from MIPI CSI-2?
MIPI’s current Camera Working Group page says the group was formed in 2004 to develop and maintain camera-interface specifications, and describes the group as active. MIPI characterizes CSI-2 as widely used in the mobile industry. Its CSI-2 page describes an image-sensor-to-application-processor interface, names D-PHY, C-PHY, and A-PHY as physical layers, and lists CSI-2 v4.2 (December 2025) as current.

| Aspect | SMIA | MIPI CSI-2 |
|---|---|---|
| Scope | A 2004 mobile camera-module architecture covering electrical, mechanical, functional, software, characterization, optical-performance, and reliability aspects. | MIPI describes CSI-2 as a high-speed image-sensor-to-application-processor interface. |
| Link or physical-layer context | The 2004 description used CCP2 for the high-speed serial link. | MIPI’s CSI-2 page lists D-PHY, C-PHY, and A-PHY. |
| Mechanical module definition | The 2004 SMIA description included socketable design and specified module outlines. | The cited MIPI CSI-2 description does not establish an equivalent module-geometry specification. |
| Software provisions | The contemporary account described a module software model and reference driver architecture. | Not stated in the cited CSI-2 page. |
| Current status cited here | Current maintenance, licensing, and compliant-module availability are not established by the cited historical sources. | MIPI identifies CSI-2 v4.2, dated December 2025, as current and says the Camera Working Group remains active. |
These descriptions show why SMIA should not be treated as simply an earlier name for CSI-2. They address different scopes in the cited material: SMIA described a whole camera module, while CSI-2 is described as a camera data interface. The available sources do not establish a one-to-one equivalence or a direct compatibility path.

Not on the basis of the SMIA name alone. The cited sources do not establish that a particular legacy Nokia module will work with a current MIPI board, nor do they provide a specific module pinout. Compatibility depends on the exact module and host, including their connector and pinout, electrical requirements, data protocol, and host support.
Before attempting a connection, obtain documentation for both the specific camera module and the board. Confirm each of those requirements against the documentation; a shared camera-standard label is not enough to establish compatibility.
