  • Software based photoflash synchronization of camera equipped portable media device and external lighting apparatus
    Patent number: 7949249
    Abstract: Methods of using software to synchronize the control of a camera on portable media device with the photoflash on an external lighting apparatus. The Camera-Equipped Portable Media Device (CEPMD) utilizes an External Lighting Apparatus (ELA) as a light source to improve the lighting conditions for portable media device photography. Both ELA and CEPMD are controlled by software, which synchronize the photoflash image capture as well as post process the image to further enhance the image quality. Furthermore, in a preferred ELA embodiment, it acts as a protective case for the CEPMD.
