Smartphone user interfaces for a RAW camera peripheral

摘要

Improved user interfaces are provided to simplify adjustments to the acquisition settings of a camera peripheral from an attached smartphone device. In one embodiment a 'live view' image stream is provided by the peripheral and displayed on the smartphone display with a range of touch controls for adjusting acquisition settings on the peripheral. As these are adjusted the user may observe the practical effects of the adjustments on the 'live view' image. The user may optionally select a range of post-processing filters implemented on the smartphone and observe the effect of such filters. In another embodiment a full-screen 'live view' is provided on the smartphone and a single, multi-component, control widget is overlaid on the 'live view'. This component incorporates one or more concentric rings with rotary sliders that can be used to adjust a range of settings for acquisition parameters dependent on the acquisition mode selected for the camera peripheral. User feedback is provided via a central circular region that changes color responsive to the 'goodness' of the selected acquisition settings. This central region also provides control means to actuate an image acquisition or to commence a video recording. Figure 10
