MAVIS: mobile acquisition and VISualization: hands on

With the advancement of mobile technologies cameras on mobile devices have improved to the point where the quality of their output is sometimes comparable to that obtained from a professional video camera. Moreover mobile cameras are being used more and more frequently in professional production environments. However, tools that allow professional users to access and display the accurate information they need to control the technical quality of their filming and make informed decisions about the scenes they are filming is missing on mobile platforms. In this paper the Mobile Acquisition and VISualisation (MAVIS) app is presented, see figure 1. By exploiting the capabilities of modern mobile GPUs, MAVIS integrates the functionalities of a vectorscope, waveform monitor, false colouring and focus peaking monitors together with all the standard functionalities of a video recording app into a single tool. With the extra information that MAVIS displays, the user is able to make informed decisions about how to light and shoot the scene. This enables high quality videos to be obtained from the mobile camera, which can be used alongside outputs of more professional cameras.
