Example Embodiment
[0022] Specific implementation mode one, combination Figure 1 to Figure 3 Explaining this embodiment, the control method of DMD in high dynamic range imaging includes the restriction on the light emphasis control weight and the restriction on the duration of each bit in the binary value of the DMD light emphasis control weight within a frame time;
[0023] Just emphasize the constraints of the control weight:
[0024] In the high dynamic light enhancement system, the dimming of a saturated pixel only needs to adjust its element value to the sensitive response zone of the image detector itself, generally the critical saturation value of the image detector and 1 / 2 critical saturation Between the values, this is a wide interval, and the upper limit and lower limit of the interval have a double relationship. Therefore, the step of light emphasis control weight can adopt a double relationship, and the light emphasis control weight can be set to several fixed values. Set the minimum li...
