The invention relates to a method and a device for converting a video image format. The method comprises the following steps of: generating a data processing unit in each central processing unit according to the number of central processing units; acquiring real-time YUV data from the outside by using a data acquisition unit and storing the YUV real-time data in a main storage unit; averagely splitting the YUV real-time data in the main storage unit into a corresponding number of equally-divided parts according to the number of generated data processing units; averagely distributing the plurality equally-divided parts of split data to each data processing unit and monitoring the running state of the data processing unit; converting split data in parallel into RGB data by using each data processing unit; and storing the converted RGB data in the main storage unit. Due to the adoption of the method and the device, the processing capability of the central processing unit can be utilized to the maximum extent and video image format converting efficiency is further improved.
