中文摘要 | 漫談影像電子電路的發展歷程。簡單的介紹類比影像到數位化處理的Image Pipeline,並以數位像機為例,敘述Image Pipeline每一級相關的演算法與實現的硬體,包含我們所提出的以統計方式切入處理的解馬賽克裝置與運用類哈爾特徵的影像辨識加速處理。接著,我們概述幾種一般常用的影像處理的硬體實現方式,包括特殊應用整合電路(ASIC),通用處理器(GPP),數位訊號處理器(DSP),和特殊應用數位訊號處理器(AS-DSP),並提出平行算數區塊(PAB)的想法來達到可程式化硬體的實現,以期保有高效價比和可程式化的彈性。 |
英文摘要 | The history of image electric circuit is introduced in this article, from analog to digital image processing. We use the example of DSC (Digital Still Camera) to describe each element in image pipeline and the relevant algorithm or implementing hardware. Additionally, we apply a statistic de-mosaicking device and speed up the pattern recognitions with Haar-like features. Beside this, we introduce general kinds of hardware implementation in image processing, like ASIC (Application Specific Integral Circuit), GPP (General Purpose Processor), DSP (Digital Signal Processor) and AS-DSP (Application Specific-Digital Signal Processor). Also, we apply a new idea of PAB (Parallel Arithmetic Block) to program the hardware, so that we can keep not only the high performance in cost ratio but also the flexibility of programmable hardware. |
