Full HD (1080p): what it is, how it works and what it does
Standard video resolution of 1920x1080 pixels, commonly recorded at 30 fps in mobile devices.
Definition and Principles
Full HD, also known as 1080p, is a standard video resolution consisting of 1920 pixels in width by 1080 pixels in height. The 'p' suffix indicates progressive scan, meaning each frame is displayed in a single pass, unlike interlaced scanning.
Architecture and Function
In the context of video recording in electronic devices, 1080p resolution is combined with a frame rate (fps) to define motion fluidity. According to the provided evidence, this resolution is frequently associated with a rate of 30 fps. This implies that the image sensor captures 30 complete frames of 1920x1080 pixels per second.
Applications and Scope
Full HD resolution is a widely adopted standard in mobile phone cameras and other consumer devices. Its presence in technical specifications, as seen in sources from smart-gsm.com and 91mobiles.com, indicates the device's capability to record high-definition video. This specification is often presented alongside other features, such as HD recording at 120 fps or Electronic Image Stabilization (EIS).
Limitations and Interpretation
While 1080p offers superior image quality to standard definition (SD), it may not be sufficient for applications requiring ultra-high definition (4K). Interpreting this specification in a product should consider the associated frame rate; for example, 1080p@30fps is the standard for smooth video under normal conditions, while other combinations may prioritize speed over resolution.
