Embodiment
For further setting forth the present invention, reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, the method of digital magnified image and its embodiment of the method for operation of graphical user interface, method, step, feature and effect thereof to proposing according to the present invention, be described in detail as follows.
Relevant aforementioned and other technology contents of the present invention, Characteristic can be known and present in the following detailed description coordinating with reference to graphic preferred embodiment.By the explanation of embodiment, when can be to reach technological means and the effect that predetermined object takes to be able to more deeply and concrete understanding to the present invention, yet appended graphic being only to provide with reference to the use with explanation be not used for the present invention to be limited.
The flow chart of Fig. 2 shows the method for operation of numeral amplification (zoom in) image method of the embodiment of the present invention and the graphical user interface (GUI) of shooting (imaging) device.Camera head in the present embodiment is digital camera, but not as limit.
First, in step 21, detect at least one object, for example people's face or non-face general object.If detecting people face can be used general human face recognition (face detection) technology; If detect non-face general object, the object image that will detect can be stored in digital camera in advance, then with general image identification technology, carry out the detecting of object.
Then, in step 22, user presses the shutter release button of digital camera to capture the image that comprises above-mentioned detecting object, and position and the size of this detecting object are recorded in digital camera.In the present embodiment, the author that the position of detecting object and size are stored in exchangeable image file format (exchangeable image file format, Exif) shelves explains (MakerNote) field, but not as limit.Above-mentioned exchangeable image file format Dang You JEIDA Japan Electronic Industry Development Association (Japan Electronic Industries development Association, JEIDA) works out.
In step 23, the image capturing is for example shown in, on the screen (liquid crystal display) of digital camera, and the object being detected is labeled (mark) out, the dotted line frame in the illustrated square 31 of Fig. 3 for example, but also can use other marking modes, for example, allow the brightness of detecting object be greater compared with the brightness of other non-detection area.
In step 24, user sends and chooses signal to digital camera by choosing control button (or other input modes), to choose detecting object, or chooses in the middle of a plurality of detecting objects.
Then,, in step 25, user sends amplifying signal to digital camera by amplifying control button (or other input modes), to choose the amplification of object.As shown in Figure 4, digital camera can, according to the position of amplifying signal and object 41, determine one and comprise the partial image 43 of choosing object in whole pick-up image 42.In details of the words, in one embodiment, according to the position of record, obtain a corner location (for example 41A) of object 41, and a corner location 42A of corresponding screen (for example whole pick-up image 42).In the middle of the line of object corner location 41A and screen corner location 42A, choose a some position (for example 43A), by the some position 43A that chooses and according to the size of record, the partial image 43 of irising out is as a ratio (scaled) region.Finally, in step 26, irised out partial image 43 is filled up and is shown in whole screen, make by this object be exaggerated and be shown in screen, as illustrated in Fig. 3 square 32.Above-mentioned steps 25 and 26 can repeat to implement with magnified image again, as illustrated in Fig. 3 square 33.
In another embodiment, in step 25, according to record position and size to obtain four corner location 41A-41D of object 41, wherein each corner location corresponds to a corner location 42A-42D of screen 42, thereby obtains four groups of position pairings (pair), that is (41A, 42A), (41B, 42B), (41C, 42C), (41D, 42D).For each group position pairing, in the middle of the line of object 41 corner location and screen 42 corner location, choose a some position.By four groups of positions, match four selected some positions, the partial image 43 of irising out is as a ratio (scaled) region.Finally, in step 26, irised out partial image 43 is filled up and is shown in whole screen, make by this object be exaggerated and be shown in screen.
According to above-described digital magnified image method, can allow user carry out rapidly browsing and amplifying of object (for example people's face), one is used example as shown in Figure 5.First, screen shows the sign (for example dotted line frame) of original pick-up image (square 51) and detecting object.In this example, total two articles is detected Bing and marks.Then,, when user chooses after the object on the right, digital camera, according to abovementioned steps 25 and 26 disclosed methods, automatically amplifies selected object and makes its middle position that is roughly positioned at screen, as shown in square 52.User can further carry out image zoom, obtains the object image (as shown in square 53) of larger enlargement ratio, can certainly carry out dwindling of image.If switching, user selects another detecting object (for example object on the left side), digital camera will automatically switch and move to this object according to the position of this object, and according to abovementioned steps 25 and 26 disclosed methods, automatically selected object amplified and make its middle position that is roughly positioned at screen, as shown in square 54.User can further carry out image zoom, obtains the object image (as shown in square 55) of larger enlargement ratio, can certainly carry out dwindling of image.
According to an embodiment, for the ease of user, for the position configuration of current show image and whole pick-up image, can there is the understanding of a summary, therefore on the screen of digital camera, more additionally demonstrate: the current region of the shown image of screen and the relative position relation of original whole pick-up image.As shown in Figure 5, for example, after object is exaggerated (square 52), in the screen upper left corner, demonstrate the relative position relation of current imagery zone 61 and original pick-up image 62.For example, after object further amplifies (square 53), in the screen upper left corner, upgrade the relative position relation that demonstrates current imagery zone 61 and original pick-up image 62.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be not depart from technical solution of the present invention content, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
