Abstract
The method includes steps: (1) local magnifying state is setup in software state of interactive interface; (2) through OSD control software, area selection box is drawn up in image plane of TV set; (3) inputting different operation codes through software, user is able to operate and select location of selection box as desired; (4) through software, user confirms the selected location; thus, output image is input to the area so as to complete magnified output of image or to recover the image back to normal frame. In time of magnifying an image, based on interpolation algorithm, area of the selected image can be enlarged to whole screen. In time of exiting the operation, interpolation algorithm does not executed, and integrated image data are written to display register. The invention is widely applicable to each type TV set.
Description
Technical field
The invention belongs to technical field of television sets, more particularly relate to the design of the arbitrary-zone amplifying method of TV images.
Background technology
Traditional television set can not carry out the image-region amplification or can only carry out the amplification of fixed position area image, and this just brings inconvenience to the user.The user may need the arbitrary region of picture is amplified so that can observe local detail sometimes, and the user need search for to determine that the part that needs to amplify is also amplified repeatedly to picture when going back some.Television set in the past then can not satisfy this demand, can not the arbitrary-zone of image be amplified.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned shortcoming and defect, and a kind of arbitrary-zone amplifying method of TV images is provided.It has a regional choice box that can move up and down for user's operation, when the user should the zone choice box move to want the position of amplifying and confirm after, just can be amplified to all over the screen by the image that this is regional.
In order to achieve the above object, the present invention includes following steps:
(1) in the interactive interface application state, local magnifying state is set;
(2) by the OSD Control Software regional choice box that in TV set image, draws;
(3) make the difference of user according to the command code of input, the position of arbitrarily operating mobile choice box by software;
(4) make the user confirm this position by software after, can be with this zone as the input of image output and finish the amplification output of image or return to normal pictures.
Above-mentioned steps (4) according to interpolation algorithm, expands to selected area image full frame when amplifying; Interpolation no longer then when withdrawing from, but complete view data is write display register.
The present invention is provided with local magnifying state in the interactive interface software state machine.After entering this state, according to default location, the regional choice box that draws, and begin to wait for that the user operates.According to the difference of command code of input, regional choice box can move to appointed positions, perhaps moves to the optional position continuously, and perhaps the zone that will select is amplified to full framely, perhaps withdraws to amplify returning to normal pictures.During amplification,, expand to selected area image full frame according to interpolation algorithm.When withdrawing from, interpolation no longer, but complete view data is write display register.
Task of the present invention comes to this and finishes.
The present invention has a regional choice box that can move up and down for user's operation, when the user should the zone choice box move to want the position of amplifying and confirm after, just can be amplified to all over the screen by the image that this is regional.It can satisfy the user arbitrary region of picture is amplified so that can observe the needs of local detail, can be widely used in the various television sets.
Description of drawings
Fig. 1 is a process blocks schematic diagram of the present invention.
Embodiment
Embodiment 1.A kind of arbitrary-zone amplifying method of TV images.It may further comprise the steps:
(1) in the interactive interface application state, local magnifying state is set;
(2) by the OSD Control Software regional choice box that in TV set image, draws;
(3) make the difference of user according to the command code of input, the position of arbitrarily operating mobile choice box by software;
(4) make the user confirm this position by software after, can be with this zone as the input of image output and finish the amplification output of image or return to normal pictures.
Above-mentioned steps (4) according to interpolation algorithm, expands to selected area image full frame when amplifying; Interpolation no longer then when withdrawing from, but complete view data is write display register.
The source code of finishing these operations is as follows:
// enter local enlarging function after, the function of the regional choice box that draws:
Embodiment 1 has a regional choice box that can move up and down for user's operation, when the user should the zone choice box move to want the position of amplifying and confirm after, just can be amplified to all over the screen by the image that this is regional.It can satisfy the user arbitrary region of picture is amplified so that can observe the needs of local detail, can be widely used in the various television sets.
