The application provides a partitioned DLP micromirror control method and system based on pixel content recognition, and relates to the technical field of DLP display. The method first receives and pre-processes an external video stream signal, extracts brightness data, and completes frame buffer updating and alignment; then determines the brightness threshold of the invalid area dynamically through an adaptive threshold brightness recognition algorithm, and marks the candidate invalid pixels; subsequently screens out static invalid pixels by using an adjacent frame difference static judgment algorithm; divides the static invalid area and demarcates the boundary coordinates through a region connectivity analysis algorithm; finally, matches the driving sub-circuit module number based on the boundary coordinates, constructs a partition control instruction, and issues it after verification and packaging. The application realizes the differential driving of the DLP micromirror partition, can completely eliminate the driving power consumption of the invalid area, improves the power consumption optimization effect, does not lose the display quality, responds in real time, has strong compatibility, and is suitable for compact DLP devices such as vehicle machines.
