RECONFIGURABLE PARALLEL IMAGE DETAIL ENHANCING METHOD AND APPARATUS

WIPO Patent Application WO/2018/126484

A1

The present invention relates to a reconfigurable parallel image detail enhancing method, comprising: parameter pre-loading, data buffering, horizontal and vertical filtering, coring filtering, overshoot suppression, amplitude suppression and cached data updating. The present invention further relates to a reconfigurable parallel image detail enhancing apparatus, comprising a local memory, a memory access control unit, a general buffer, a parallel arithmetic logic unit (ALU), a state machine and a parallel multiply-accumulator (MAC). The present invention enhances an image detail signal, so that a textured area is more clear, and improves the data usage efficiency of same, reduces the data interaction between an operational component and a peripheral memory, lowers the memory access bandwidth pressure, and can achieve the repeated utilization of hardware resources.
