The invention provides an image collecting control device and method. In practical instrument image collecting, the device drives an image collector located at the tail end of the device to change a collecting position by controlling a fixing support to move, and therefore instrument images of multiple instruments can be collected in sequence through one image collector, and the image collecting cost is lowered. A DSP is used for controlling the image collector to conduct image collecting, an ARM processor is used for achieving man-machine interaction, a servo power mechanism is controlled to adjust the moving track of the fixing support, and therefore the collecting position of the image collector is adjusted. It is clear that the control mode with the ARM and the DSP is adopted so that the image collecting control device can meet the practical requirements for the high code density, the high storage device utilization rate, the high control capability and the like.
