METHOD OF CALCULATING OVER-DRIVE TARGET

摘要

The present invention provides a method for calculating an over-drive target, which follows a predetermined sequence to perform trials of over-drive target values to identify the R/G/B brightness-response time curve of the over-drive target value that matches target brightness and compares response time of the R/G/B brightness-response time curve that matches the target brightness to identify the over-drive target value, whereby achieves automatic calculation of the over-drive target value of the over-drive chart so as to save human labor, increase efficiency, be better fit to the principle of the over-drive technique, and provide an excellent effect of over driving.

1. A method for calculating an over-drive target, comprising the followings steps:
(1) performing dynamic switching among four frames, which includes a first to a fourth frames, according to a starting grey level and an ending grey level of a selected chart of an over-drive table to be completed; (2) trying an over-drive target value in order to obtain an R/G/B brightness-response time curve of the over-drive target value; (3) subjecting the R/G/B brightness-response time curve obtain in step (2) to a noise reduction and smoothening treatment; (4) taking brightness value of the third frame of step (1) as target brightness and determining if the R/G/B brightness-response time curve obtained with the over-drive target value shows brightness that matches the target brightness and if yes, going to step (5), otherwise repeating steps (2)-(4); (5) if the brightness of the R/G/B brightness-response time curve of the over-drive target value of the trial is first brightness that matches the target brightness, filling the over-drive target value in a corresponding position in the over-drive table to be completed and repeating steps (2)-(4); and if the brightness of the R/G/B brightness-response time curve of the over-drive target value of the trial is not first brightness that matches the target brightness, comparing response time of the R/G/B brightness-response time curve obtained with the over-drive target value to response time of the R/G/B brightness-response time curve obtained with an over-drive target value set in a corresponding position in the over-drive table to be completed and going to step (6); (6) if the response time of the R/G/B brightness-response time curve obtained with the over-drive target value of the trial is less than the response time of the R/G/B brightness-response time curve obtained with the over-drive target value of the corresponding position in the over-drive table to be completed, replacing the over-drive target value of the corresponding position in the over-drive table to be completed with the over-drive target value of the trial and repeating steps (2)-(5); if the response time of the R/G/B brightness-response time curve obtained with the over-drive target value of the trial is greater than the response time of the R/G/B brightness-response time curve obtained with the over-drive target value of the corresponding position in the over-drive table to be completed, setting the over-drive target value of the corresponding position in the over-drive table to be completed to be finally determined over-drive target value and going to step (7); and (7) repeating steps (1)-(6) until calculation of all over-drive target values of the over-drive table.
