Specific implementation mode
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
As shown in FIG. 1, FIG. 1 is the present invention to scale signal picture and the first embodiment for the method for scaling register mapping
Flow chart.The method for the scaling signal picture and scaling register mapping that the present embodiment is mentioned, including：
Step S10 receives triggering command；
The present embodiment can be applied in the display equipment of adjustable picture scaling, such as television set, display, notes
This computer, integrated computer etc..The present embodiment is by taking television set as an example, when user needs the picture scaling of adjusting television set
When, the setting menu page of television set is turned on, cursor is switched at the ratio mode option in setting menu, that is, generated tactile
Send instructions, triggering command is sent to the CPU of television set by display module.Television set includes multiple ratio modes, such as including 4:
3、16:9, Auto etc., or including standard, full frame, amplification, stretching, widescreen etc..Current television machine can be only shown in setting menu
Aspect ratio corresponding to ratio mode option, such as current television machine aspect ratio be 16:9, then in only display scale
The mode option 16:9.In addition it is also possible to which all ratio mode options are shown in setting menu page.
Step S20 obtains the number of ratio mode option, scales the digit of register and scales each period in register
Corresponding numerical value；
After obtaining triggering command, CPU executes matching operation on backstage.CPU obtains the total number of ratio mode option, often
One ratio mode option corresponds to a scaling signal picture.Scaling register also current to television set CPU is identified, and obtains
The digit of register must be scaled, such as the digit of 8 scaling registers is 8bit, the digit of 16 scaling registers is 16bit,
The digit of 32 scaling registers is 32bit etc..Matching operation in the present embodiment can when using television set for the first time or
It is carried out after having replaced scaling register every time, therefore triggering command can also generate under the foregoing conditions.In scaling register
Be stored with numerical value, the different periods corresponds to different numerical value, such as 16 scaling registers include 0x0100,0x0200,
Tri- numerical value of 0x0300.
Step S30 judges whether corresponding numerical value of each period is effective according to the number of ratio mode option；
It, need to be to the effective of each numerical value in scaling register in order to avoid scaling signal picture and scaling register mismatch
Property judged, mainly judge whether the number for scaling the numerical value in register has exceeded the ratio mode option of television set
Number illustrates that there are assignment for the scaling register if so, it will cause scaling signal pictures and scaling register value to mismatch
The possibility of mistake shows if carrying out matching using the numerical value in the scaling register at this time, will appear can not find it is matched
The case where scaling signal picture, thus scale any of register numerical value it is invalid when, can to user's display reminding information, or
The numerical value in scaling register is modified automatically by display equipment.
Step S41 is generated when any of corresponding numerical value of each period is invalid according to the number of ratio mode option
Multiple new numerical value with reference format；
Each new numerical value is corresponded to each period and is assigned to scaling register successively by step S42；
When any of scaling register numerical value is invalid, scaling is reset according to the ratio mode option number of television set
Register.For example, ratio mode option includes 4:3、16:9, tri- options of Auto then generate three numerical value according to reference format
Newly-generated numerical value 0x01,0x02,0x03 are assigned to scaling register by 0x01,0x02,0x03 successively, complete resetting scaling
Register.
Step S50 corresponds new numerical value and ratio mode option and scaling signal picture；
Each numerical value in scaling register after resetting is illustrated into picture one by one with each ratio mode option and scaling respectively
It is corresponding, such as 0x01 correspondences 4:3 options, while it is 4 also to correspond to ratio:3 scaling illustrates picture.
Step S60 obtains user's selection when receiving the ratio mode option of user's selection in scaling register
The corresponding new numerical value of ratio mode option, and show the corresponding scaling signal picture of new numerical value.
When user selects some ratio mode option on menu is arranged, such as select 4:3 options, then display are set
The standby option according to user's selection gets corresponding numerical value in scaling register, and finds correspondence according to the numerical value got
Scaling illustrate picture, will scaling signal picture according to preset display time showing on the screen of a display device, such as show
Show 3 seconds, the display effect of selected ratio mode option is checked for user.After the preset display time reaches, display equipment is closed
The scaling signal picture currently shown is closed, avoids display overlong time from influencing user and watches normal TV programme.In addition also may be used
Not scale the display for illustrating picture to control using the preset display time and be automatically closed, but signal picture is scaled in display

Flow chart.The present embodiment includes the steps that embodiment illustrated in fig. 1, further includes after step S30：
Step S70 shifts each number when each period, corresponding numerical value was all effective according to the digit of scaling register
Value, by each numerical value be converted to reference format and include significance bit new numerical value.
In the present embodiment, when scale the numerical value in register it is effective when, it is contemplated that the diversity of register, different registers
Digit it is different, cause the position of the significance bit of numerical value may disunity.Such as the numerical value in 8 scaling registers is 0x01,
Numerical value in 16 scaling registers is 0x0100, and the numerical value in 32 scaling registers is 0x010000,64 scaling deposits
Numerical value in device is 0x01000000, this makes a scaling signal picture needs and multiple values match, is easy error.In order to

Validity judged, mainly judge whether the number for scaling the numerical value in register has exceeded the ratio mode of television set
Option number, also judges whether the numerical value scaled in register is ranked sequentially according to numerical values recited.Scale numerical value in register
Significance bit is typically that the numerical value in fixed bit, such as 8 scaling registers is 0x01, and significance bit is 0~3,16 scalings
Numerical value in register is 0x0100, and significance bit is 8~11.For the ease of sentencing to the numerical value validity for scaling register
It is disconnected, default value range is arranged according to the number of the digit of scaling register and ratio mode option.For example, ratio mode option
Number be 3, then the default value range of 8 scaling registers is set to 0x03, by the preset number of 16 scaling registers
Value range is set as 0x0300；For another example, the number of ratio mode option is 15, then by the default value model of 8 scaling registers
It encloses and is set as 0x0F, set the default value range of 16 scaling registers to 0x0F00.If scaling the number in register
When value has exceeded default value range, then illustrate that the numerical value number for scaling register has exceeded the ratio mode option of television set
Number, although scaling register numerical value number be less than or equal to television set ratio mode option number, may scale
There is assignment mistake in register, then the numerical value for scaling present period in register at this time is invalid, need to be revised to it.
If the numerical value in scaling register is belonged within the scope of default value, judge that the numerical value for scaling present period in register has
Effect.The present embodiment is judged by the validity to numerical value in scaling register, is avoided because the numerical value of scaling register goes out
Mistake causes scaling signal picture to be mismatched with scaling register, is conducive to scaling signal picture and normally switches.
