To verify the effect of Turbo Luminance function, we measured the contrast response time in 3 different settings:
i. the normal setting (Fig.2)
ii. only the brightness is maximized (Fig.3)
iii. Turbo Luminance function is ON (Fig.4)
In the normal setting, the DICOM GSDF curve is nearly flawlessly reproduced, while in the setting where only the brightness is maximized, the deviation gradually become larger as the brightness increases. In other words, it deviates from the DICOM GSDF curve, resulting in deterioration of gamma characteristics.
On the other hand, when Turbo Luminance function is ON, the DICOM GSDF curve is maintained as same as in the normal setting and the brightness is maximized.
