This paper describes VHD (very high definition) image media competing in spatial resolution with the familiar film media as a new digital image media concept, and discusses a problem of image acquisition as a key technology for achieving VHD image systems. Towards the development of a VHD image acquisition system, the work presents a new signal-processing based approach using multiple different cameras. The image acquisition approach, processing and integrating multiple images taken simultaneously with multiple different cameras, produces an improved spatial resolution image with sufficiently high signal-to-noise ratio. Theoretical analysis and experimental simulations show clearly the improvement in the high frequencies and details.
