In some embodiments, modulating a display pixel refresh rate a predetermined amount relative to a target camera frame rate conveys hidden image data. In further embodiments, a camera module is employed to detect one or more changes in state and/or logic level associated with the pixel refresh rate modulation. The logic levels are then decoded to deduce the hidden image data. In some embodiments, a visually perceptible representation of the hidden image data is then output to a output panel. For example, in one exemplary embodiment the hidden image data includes a pixel value indicative of a color that is to be output to one or more pixel of a camera viewer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Conveyance of hidden image data between output panel and digital camera","description":"One or more system, apparatus, method, and computer readable media is described below for conveyance of hidden image data between a display and a camera.
