Novel projected image horizontal correction device

The utility model discloses a novel projected image horizontal correction device, its characterized in that: correcting unit in be equipped with the CCD camera and gather and to send into flush bonding processor behind the projection picture and handle, flush bonding processor judges that the DMD chip that drives on the DLP circuit board through motor -drive circuit drive rotary stepper motors rotates behind projected image's the horizontal angle. Owing to adopt foretell structure, the utility model discloses need not carry out the function that regular calibration just can the completion level be corrected at the in -process that uses, along with the increase of live time, the precision of level correction can not receive any influence yet moreover. 本实用新型公开了种新型的投影图像水平校正装置，其特征在于：所述的校正装置内设有CCD摄像头采集投影画面后送入嵌入式处理器进行处理，嵌入式处理器判断投影图像的水平角度后通过电机驱动电路驱动旋转步进电机带动DLP电路板上的DMD芯片转动。由于采用上述的结构，本实用新型在使用的过程中不需要进行定期的校准就可以完成水平矫正的功能，而且随着使用时间的增加，水平矫正的精度也不会受到任何影响。
