Apparatus and methods are presented for a touch user interface using an image sensor. A method for processing image-based input commands for a user interface includes receiving image frames from a sensor, determining when the sensor enters a cover state, determining, from subsequent image frames, when the sensor enters a de-cover state, analyzing information based upon the subsequent image frames to interpret a user command, and issuing the user command to a user interface. An apparatus having an image-based user interface includes an image sensor, and a processor connected to a memory, where the processor is configured with logic to receive image frames from the image sensor, to determine when the image sensor enters a cover state, determine, from subsequent image frames, when the image sensor enters a de-cover state, to analyze information based upon the subsequent image frames to interpret a user command, and to issue the user command to a user interface.
