What is ISO 20954‑1 – Optical systems in digital cameras about ?  
ISO 20954‑1 is the first part of the ISO 20954 series that discusses measurement methods for image stabilization performance of digital cameras. ISO 20954‑1 discusses the measurement methods for image stabilization performance of optical systems.
ISO 20954‑1 defines the measurement method of optical image stabilization performance for still images compensating for handheld blur consisting of two rotational components, yaw, and pitch.
ISO 20954‑1 applies to consumer digital cameras with optical image stabilization for still images. Apparatuses such as camcorders and mobile phones with still image shooting functionality are within the scope of ISO 20954‑1. 
Who is ISO 20954‑1 – Optical systems in digital cameras for ?
ISO 20954‑1 on optical systems in digital cameras is useful for: 
- Manufacturers of digital cameras
- Optical engineers
- Image Quality researchers
Why should you use the ISO 20954‑1 – Optical systems in digital cameras ?
The image stabilization function is important for digital cameras and has become a selling point in marketing materials. Therefore, the measurement methods and its reporting method are then very important to compare the image stabilization performance among cameras based on their brochures.
ISO 20954‑1 is to specify how to measure the optical image stabilization performance of a camera held in the user’s hands. ISO 20954‑1 specifies two waveforms that simulate the important characteristics of how a camera shakes when it is held by hand.
The guidelines of ISO 20954‑1 also help you to:
- Remove the effects of factors other than camera shake from the total image degradation amount
- Enable the calculation of optical image stabilization performance even for cameras incapable of turning off the optical image stabilization function.
Overall, the guidelines of ISO 20954‑1 help you to improve the image stabilization performance of optical systems in your digital cameras, thereby enhancing their quality.
