The invention discloses a method and a device for loading and measuring data of an image processing device, which is characterized in that loading programs are stored in a first address of a flash; during loading and starting, a DSP transfers a loading program module to a memory; a plurality of image processing programs to be loaded are stored in a successive address of the flash; and the DSP switches between the loading programs and the plurality of image processing programs according to received instruction information so as to finish flash data loading, channel testing and other testing tasks. After the image processing device is encapsulated, the invention updates and maintains the programs, enables different image processing programs according to different target types and is convenient in operation and high in reliability.
