Embodiment
Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, the method of the digital magnified image that foundation the present invention is proposed and its embodiment of method of operation, method, step, feature and the effect thereof of figure user interface, describe in detail as after.
Relevant aforementioned and other technology contents, characteristics and effect of the present invention can be known to present in the following detailed description that cooperates with reference to graphic preferred embodiment.By the explanation of embodiment, when can being to reach technological means and the effect that predetermined purpose takes to be able to more deeply and concrete understanding to the present invention, yet appended graphic only provide with reference to the usefulness of explanation, be not to be used for the present invention is limited.
The flow chart of Fig. 2 shows the method for operation of numeral amplification (zoom in) image method and the figure user interface (GUI) that shooting (imaging) is installed of the embodiment of the invention.Camera head in the present embodiment is a digital camera, but not as limit.
At first, in step 21, detect at least one object, for example people's face or non-face general object.If detecting people face then can use general human face recognition (face detection) technology; If detect non-face general object, then the object image that will detect can be stored in advance in the digital camera, carry out the detecting of object again with general image identification technology.
Then, in step 22, the shutter release button that the user pushes digital camera comprises the image of above-mentioned detecting object with acquisition, and the position and the size of this detecting object then are recorded in the digital camera.In the present embodiment, detecting position of object and size are stored in exchangeable image file format (exchangeable image file format, Exif) author of shelves explain (MakerNote) field, but not as limit.(Japan Elect ronic Industries development Association JEIDA) works out above-mentioned exchangeable image file format shelves by JEIDA Japan Electronic Industry Development Association.
In step 23, institute's picked image is shown on the screen (for example LCD) of digital camera, and the object that is detected is labeled (mark) and comes out, the frame of broken lines 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 than the brightness of other non-detection area.
In step 24, the user sends and chooses signal and give digital camera by choosing control button (or other input modes), to choose the detecting object, perhaps chooses in the middle of a plurality of detecting objects.
Then, in step 25, the user sends amplifying signal to digital camera, to choose the amplification of object by amplifying control button (or other input modes).As shown in Figure 4, digital camera can determine one and comprise the partial image 43 of choosing object according to the position of amplifying signal and object 41 in whole pick-up image 42.Detailed it, in one embodiment, obtain the corner location (for example 41A) of object 41 and a corner location 42A of corresponding screen (a for example whole pick-up image 42) thereof according to the position of record.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 of being irised out 43 is promptly as a ratio (scaled) zone.At last,, the partial image of being irised out 43 filled up be shown in whole screen, make object be exaggerated by this and be shown in screen, as illustrated in Fig. 3 square 32 in step 26.Above-mentioned steps 25 and 26 can repeat to implement with magnified image once more, as illustrated in Fig. 3 square 33.
In another embodiment, in step 25, according to the record the 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).At 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 selected some positions of pairing, four groups of positions, the partial image of being irised out 43 is promptly as a ratio (scaled) zone.At last,, the partial image of being irised out 43 filled up be shown in whole screen, make object be exaggerated by this and be shown in screen in step 26.
According to above-described digital magnified image method, can allow the user carry out browsing of object (for example people's face) apace and amplify, one is used example as shown in Figure 5.At first, screen shows the sign (for example frame of broken lines) of original pick-up image (square 51) and detecting object.In this example, total two articles is detected Bing and is marked.Then, choose the object on the right as the user after, digital camera is promptly according to abovementioned steps 25 and 26 disclosed methods, automatically selected object amplified and makes its middle position that roughly is positioned at screen, shown in square 52.The user can further carry out image and amplify, and obtains the object image (shown in square 53) of bigger enlargement ratio, can certainly carry out dwindling of image.If switching, the user selects another detecting object (for example object on the left side), then digital camera will automatically switch according to the position of this object and move to this object, and according to abovementioned steps 25 and 26 disclosed methods, automatically selected object is amplified and make its middle position that roughly is positioned at screen, shown in square 54.The user can further carry out image and amplify, and obtains the object image (shown in square 55) of bigger enlargement ratio, can certainly carry out dwindling of image.
According to an embodiment, for the position configuration of present show image and whole pick-up image one understanding of summarizing can be arranged for the ease of the user, therefore more extra demonstrating on the screen of digital camera: the zone of the shown image of screen and the relative position relation of original whole pick-up image at present.As shown in Figure 5, after object is exaggerated (for example square 52), demonstrate the relative position relation of present imagery zone 61 and original pick-up image 62 in the screen upper left corner.After object further amplifies (for example square 53), go out the relative position relation of present imagery zone 61 and original pick-up image 62 in screen upper left corner update displayed.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, though the present invention discloses as above with preferred embodiment, yet be not in order to limit the present invention, any those skilled in the art, in not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solution of the present invention content, according to technical spirit of the present invention to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
