From a Bare CMOS Sensor to a Complete (Smart) Camera
Vision is one of the most powerful – and complex – sensing capabilities in robotics. Cameras enable navigation, object detection, inspection and interaction, but they also introduce significant technical challenges around image quality, latency, lighting robustness and processing.
At the architectural level, teams must decide whether to build a vision solution from a raw CMOS sensor and custom image signal processing (ISP), or to rely on complete camera modules or smart cameras provided by specialised manufacturers.
This decision has a direct impact on image quality, development effort and time-to-market.

The Core Dilemma: Speed, Quality, or Both?
Deciding whether to build a custom vision solution from the ground up or to purchase a complete camera system is a critical step in developing advanced robotics. The choice impacts everything from image quality and system flexibility to development time and overall project cost.

Questions Teams Should Ask Before Choosing
- What image quality and performance specifications are truly required?
- Under which lighting and environmental conditions must the camera operate?
- Do we have in-house expertise to tune and validate an ISP pipeline?
- Are we willing to invest in optical and image-processing lab infrastructure?
- Are suitable COTS camera solutions already available?
- How much customisation is realistically required?
- How critical is time-to-market for the project?
