Further, we define an 8 x 8 pixel block as the smallest unit for infrared indication, which has 0 to 64 levels of infrared intensity. When the 64-point switch is completely closed, the transmitted infrared light is 0; the even switches are opened according to the rule that the odd switches are closed, 32 pixel switches are opened, and the 32 pixel switches are closed, so that the transmitted infrared light is half of that of the full-open infrared light; when the 64 switches are all on, the maximum infrared signal output is reached.
The target image is decomposed into a plurality of infrared indication minimum units, so that the target outline and the infrared intensity can be drawn.
