Number Lmid, such as the first parameter Lmax1 is determined as intermediate parameters.Then, in the first process h1: can under second mode 2,
Second gamma curve according to corresponding to second mode 2 by the parameter of picture from parameter current L3 be adjusted to intermediate parameters (namely
First parameter Lmax1) after, Modes of Parameters is switched into first mode 1.In first process h2: under first mode 1,
First gamma curve according to corresponding to first mode 1 adjusts the parameter of picture from intermediate parameters (namely first parameter Lmax1)
It saves to target component L4.
In the present embodiment, the first mode of brightness regulation is carried out, second mode can use the bit number table of predetermined width
Show, for example, 8 bits, 16 are than top grade, can according to minimum brightness in the accuracy requirement of brightness regulation, mode and maximum brightness it
Between luminance difference number of bits is configured.Under same brightness difference, number of bits is bigger, and one numerical value of every change is (such as
" 3 " are adjusted to from " 2 ") its generated brightness change is smaller, and the precision for carrying out brightness regulation is higher.
For example, it is assumed that the brightness of brightness regulation mode is indicated with 8 bits, it can be by minimum corresponding to the mode
Brightness is divided into 256 sections to maximum brightness, and parameter is that " 0 " indicates that the minimum brightness of the mode, parameter are that " 255 " indicate to be somebody's turn to do
The maximum brightness of mode.
By taking Fig. 3 b as an example, it is assumed that in second mode 2: being that parameter at L3 corresponding to it is 240, is in brightness in brightness
The corresponding parameter in the place Lmax1 is 130.In first mode 1: be the corresponding parameter in the place Lmax1 in brightness being 255, bright
It is 200 that degree, which is the corresponding parameter in the place L4,.It determines picture according to the pattern switching instruction received from the second current mould
Formula 2 switches to first mode 1, and when the brightness of picture is adjusted to L4 from L3.In first process h1: can be in second mode 2
Under, the parameter of picture 240 is adjusted to Lmax1 institute corresponding to the L3 by second gamma curve according to corresponding to second mode 2
After corresponding 130, Modes of Parameters is switched into first mode 1.In first process h2:, now will ginseng under first mode 1
Number is adjusted to 255 from 130, and then first gamma curve according to corresponding to first mode 1 is right from Lmax1 institute by the parameter of picture
255 answered are adjusted to parameter 200 corresponding to L4.
