The first challenge is that on e-paper platforms, it is difficult to achieve real-time image processing using low-power microcontrollers. The second issue is its time complexity remains high, making it still challenging to implement this algorithm on existing e-paper platforms. To tackle these problems, this thesis proposes a parallelized hardware architecture for halftone image processing on color e-paper, along with a novel pixel search order matrix. This hardware architecture exhibits excellent adaptability and scalability, allowing for flexible expansion or reduction of parallelized modules to meet the equirements of different systems. Furthermore, the proposed hardware architecture has been implemented on a chip platform, and experimental results demonstrate its efficient execution of real-time image processing while maintaining image quality.彩色電子紙直接二元搜尋影片半色調硬體設計影像處理晶片Color electronic paperDirect binary searchVideo halftoningHardware designImage processing chipetd
