Degree, desired light colour carry out numerical value and make the difference, and respectively obtain contrast difference, colour difference, the above are difference results.
The above difference is compared by step 205 with desired threshold, judge these differences whether among threshold value, if
Then follow the steps 206, it is no to then follow the steps 207.
Desired threshold includes at least: reasonable contrast degree difference threshold value, ideal chromatic aberation threshold value, desired color temperature difference threshold value.
Step 206 is adjusted difference, so that it within threshold range, is adjusted result.Step is executed later
207。
Specifically, being boundary with natural number 0 compared with contrast difference is made the difference with reasonable contrast degree difference threshold value further progress
Limit contrast numerical value is turned up, if contrast difference lower than result is made the difference less than 0 if reasonable contrast degree difference threshold value conversely, doing
Poor result can be greater than 0, then turn down contrast numerical value.Similarly chromatic aberation and colour temperature are adjusted.
Step 207, according to angle calcu-lation result and adjustment as a result, the virtual image to output couples, obtain coupling image.
Step 208, presentation device are projected image is coupled.
Presentation device sends coupling image, inside this device after optical path reflects, coupling image is sent to reflection and is situated between

8. device according to claim 7, which is characterized in that the optocoupler seaming element, comprising:
Light data comparing unit, the light data and ideal light data for parsing the light resolver carry out
Compare the scheme of being adjusted；
Angle-unit, what Adjusted Option and the data processing equipment for being obtained according to the light data comparing unit obtained
Angle calcu-lation result is adjusted to image to be projected.
9. device according to claim 8, which is characterized in that the light data comparing unit is specifically used for:
Respectively to the contrast, colour and reasonable contrast degree, colour is made the difference, and obtains contrast difference, colour difference；
The contrast difference, respectively with reasonable contrast degree difference threshold value, ideal chromatic aberation threshold value is compared, obtains colour difference
The Adjusted Option；
Specifically, needing for the contrast to be turned up, instead if the contrast difference is lower than the reasonable contrast degree difference threshold value
Turn down, fall in it in default contrast threshold, the colour difference handled in the same way, is obtained
The Adjusted Option.
10. device according to claim 9, which is characterized in that the optocoupler seaming element, comprising:
Light adjusts coupling unit, and the Adjusted Option for being obtained according to the light data comparing unit is to the figure to be projected
The contrast of picture, colour are adjusted, and the angle calcu-lation for being also used to be obtained according to the angle-unit is as a result, described in coupling
Optical path image to be projected obtains coupling image；
Output unit, for sending the coupling image to the presentation device.
