英文摘要The invention relates to a device for real-time image statistics with a histogram and a method for implementing the same. The device comprises a video decoding unit, a programmable logic gate array, aprogram storage, a clock management unit, a resetting management unit and a power supply management unit, wherein the video decoding unit receives, filters, amplifies and digitalizes an original image signal to generate video data the programmable logic gate array receives video data output by the video decoding unit and performs the statistics of the video data with the histogram the program storage stores the application programs of the programmable logic gate array the clock management unit provides required clocks for the programmable logic gate array and the video decoding unit the resetting management unit provides a resetting signal for the programmable logic gate array and the power supply management unit provides required power supply for the programmable logic gate array and units. The method comprises that: the video decoding unit receives, filters, amplifies and digitalizes the original image signal to generate the video data and the programmable logic gate array performs the statistics of the video data with the histogram to obtain a result. The device and the method have the advantages of quickness, high integration level, low cost, and the like.
