The invention discloses an image processing circuit, comprising a control circuit and a multiscale decomposition circuit. The multiscale decomposition circuit is used for carrying out multiscale decomposition on image data and obtaining a plurality of pieces of sub-band data in parallel. The control circuit is used for controlling the multiscale decomposition circuit to carry out many times of multiscale decomposition iteratively. The process of carrying out many times of multiscale decomposition iteratively indicates that at least part of the plurality of pieces of sub-band data output at the former time is taken as input of the multiscale decomposition carried out at the latter time. According to the image processing circuit, both the occupied resource quantity for processing multiscale images and the efficiency of processing the multiscale images are taken into consideration. 种图像处理电路，包括：控制电路和多尺度分解电路；其中：所述多尺度分解电路，适于对图像数据进行多尺度分解，并行得到多个子带数据；所述控制电路，适于控制所述多尺度分解电路迭代地进行多次多尺度分解，所述迭代地进行多次多尺度分解是指：将前次输出的多个子带数据中的至少部分作
