Image generation method and device of signal generator

The invention relates an image generation method and device of a signal generator, the signal generator, computer equipment and a computer storage medium. The method comprises the following steps: acquiring an image generation instruction, wherein the image generation instruction comprises image identification information and image parameter information; searching an image drawing algorithm corresponding to the image identification information from a preset image drawing method according to the image identification information, wherein the image drawing algorithm is used for representing a partition drawing rule and a partition compression rule of the image; drawing various partition images according to the image parameter information and the image drawing algorithm, compressing various partition images, and writing various compressed partition image into the memory. Through above technical scheme disclosed by the invention, the complex image needing to be generated is drawn accordingto the partition drawing
