摘要: 本实用新型涉及一种图像实时直方图统计装置,该装置包括视频解码单元,接收原始图像信号进行滤波、放大及数字化处理,生成视频数据;可编程逻辑门阵列,接收视频解码单元输出的视频数据,对视频数据进行直方图统计;程序存储器,用于存储可编程逻辑门阵列的应用程序;时钟管理单元,为可编程逻辑门阵列以及视频解码单元提供所需要的时钟;复位管理单元,为可编程逻辑门阵列提供复位信号;电源管理单元,为可编程逻辑门阵列及各单元提供所需电源。本实用新型利用可编程逻辑门阵列实时地实现直方图统计,为后续其他图像处理算法提供良好基础,具有快速性、集成度高、低成本等特点。
英文摘要: The utility model relates to an image real-time histogram statistic apparatus, which comprises a video decoding unit, a programmable logic gate array, a program storage unit, a clock management unit, a return management unit and a power-supply management unit, wherein, the video decoding unit receives an original image signal to be filtered, amplified and digitalized to generate a video data the programmable logic gate array receives the video data which is outputted by the video decoding unit and performs the histogram statistics to the video data the program storage unit is used for storing an exercise program of the programmable logic gate array the clock management unit supplies the required clock to the programmable logic gate array and the video decoding unit the return management unit supplies a return signal to the programmable logic gate array the power-supply management unit supplies power to the programmable logic gate array and each unit. The programmable logic gate array can be used to realize the real-time histogram statistics, thereby supplying a favorable foundation for the following processing algorithm of other images. The image real-time histogram statistic apparatus has the advantages of rapidness, high integration, low cost, and the like.
