| Popis: | With rapid progress of sensors, display devices, and computing engines, image application exists everywhere. High quality, high compression rates of digital image and low computational cost are important factors of consumer electronics. In this paper, we proposed a 4:4:4 lossless JPEG XR encoder design. In JPEG XR encoder, entropy coding is a critical module of encoder. We proposed a well-defined timing schedule of pipeline architecture to speed up the entropy encoding, which is the most computationally intensive part in JPEG XR encoder. This design can be used for the digital photography applications to achieve the low complexity of computation, low storage, and high dynamic range. |
