The user by on the remote controller/following key adjusts the parameter value that black level extends, MCU adjusts effect that the black level in the professional test image extends simultaneously and send display module to show adjusted professional test image simultaneously.When the user transfers parameter value when big, can see that the contrast of adjacent GTG is strengthened, promptly black seems more black, the level of dark part and expressive force are abundant more and strong in this sampled images; When the user turned parameter down, the contrast of adjacent GTG weakened, and it is comparatively soft that image seems.
Specifically, MCU can send corresponding order to black level and extend process chip after the adjustment instruction of receiving remote controller.This chip has relevant register, and after the parameter of revising register, the effect that black level extends will change, thereby shows on screen.Adjust for the ease of the user, the parameter value of this moment also can be presented on the screen, and changes along with user's control.
(3) withdraw from test pattern: when the user has adjusted to satisfied effect, confirm this adjustment result, preserve adjusted parameter, and withdraw from image quality and adjust state.
After the user withdrawed from image quality adjustment state, television image occurred, and had adopted new parameter this moment.Adjusted parameter can be kept in the memory device of system, when needs refresh the chip register parameter, and for example start, MCU can take out the parameter after the user adjusts affirmation from memory device, and is transferred in the register of chip.The debug results that can guarantee the user so just can be embodied in the television image always,
In concrete the application, more than one of the parameter that corresponding image quality is adjusted, all need the professional test image as a reference as definition, black level extension, noise reduction mode, the isoparametric adjustment of flesh correction, it under the ideal situation the corresponding specific professional test image of a parameter, when the user adjusted certain specific parameter, MCU called the specific professional test image of this parameter correspondence.
It also can be the adjustment that a professional test image is applicable to a plurality of parameters, or the adjustment of a parameter needs with reference to a plurality of professional test images, specific design can be considered actual conditions, adjusts the easy while with the user and can reach desirable adjustment effect again and be as the criterion.
Adjustment a parameter needs with reference under the situation of a plurality of professional test images, can use special-purpose menu to show the title of professional test image, the user is by changing the professional test picture material to the selection of menu item, and the interface of this menu and mode of operation can be identical with the style of other menu of system.
Can also increase help information in addition in menu, in real time how guides user carries out next step operation, and provides the technological guidance that how to be only optimum state etc.
