Method for optimizing image signal processing

A method and apparatus for optimizing image signal processing, where the image signal processing comprises a plurality of separate sub-tasks performed in a predetermined order, where the method comprises the steps of: defining a first group of sub-tasks, the first group having a starting point and an ending point in the predetermined order, and comprising at least two or more sub-tasks; executing the subtasks according to a predetermined sequence until the starting point of the first group; executing the subtasks of the first group by using a preset first parameter set until the end point of the first group; modifying a predetermined first parameter set; and executing the subtasks of the first group with the modified first set of parameters until the end point of the first group. 一种用于对图像信号处理进行优化的方法和设备，其中，图像信号处理包括以预定顺序执行的多个单独的子任务，其中，该方法包括以下步骤：定义第一组的子任务，第一组具有按照预定顺序的起点和终点，并且包括至少两个或更多个子任务；按照预定顺序执行子任务，直到第一组的起点；用预定的第一参数集执行第一组的子任务，直到第一组的终点；修改预定的第一参数集；以及用修改的第一参数集执行第一组的子任务，直到第一组的终点。
