Embodiment
Below with reference to the embodiment accompanying drawing, describe the invention described above in detail.
Fig. 1 is the mobile communication terminal pie graph of one embodiment of the invention.As shown in the figure, it constitutes identical with general terminal formation substantially.But difference of the present invention is that image processing part 20 is handled the image that obtains from camera section 10, and it is object according to the observation, and by different sharpening algorithm process images, this point is different in action with the general terminal that constitutes.
Promptly, user's operation inputting part 50, enter set magnifying glass menu, after the multiplying power that selection needs maybe will be used the object of magnifying function, control part 30 receives user's selection, start camera section 10, reception is worked by different way from the image processing part 20 of the picture signal of camera section 10 outputs.Above-mentioned image processing part 20 amplifies the image that obtains from above-mentioned camera section 10 with digital form, by sharpening (sharpness) algorithm, becoming more distinct image because of the fuzzy image processing of shooting at close range.This bluring is because the camera lens of mobile communication terminal has certain critical distance, generally speaking, the camera of mobile communication terminal is not supported macroshot, camera when the target object, the misalignment focus, the target object image blur uses magnifying function just in order to remedy this problem.
When the profile of comparison film or object is amplified,, but can also distinguish to a certain extent, but that when being literal or symbol etc. when requiring shrewd object the sharpening algorithm by general coloured image is implacable even have necessarily fuzzy.Therefore, the user passes through menu, divide into photo and document, select the object of observation, when selecting document (literal or symbol etc.), be picture conversion gray scale (gray scale), make it to meet application target, use sharpening algorithm then, thereby can confirm literal or symbol more clearly gray scale.This gray scale sharpening is being that literal such as in white and black book, newspaper, advertisement have outstanding performance when amplifying to the object of observation.Therefore, if the user can utilize volume key (side key) or directionkeys to regulate the sharpening program, can carry out literal interpretation more accurately so.For example, if make the user can regulate brightness (brightness) and contrast (contrast), or can regulate can the above-mentioned two kinds of parameters of disposable adjusting gamma (gamma) value, just can in gray scale, obtain the picture rich in detail of high contrast, make magnifying function realize maximization.
For this reason, above-mentioned image processing part 20 need have and amplify relevant image processing algorithm, the sharpening algorithm of coloured image and the sharpening algorithm of gray level image, and control part 30 is according to user's selection, and selecting to start will be by the algorithm of image processing part 20 enforcements.
It should be noted that under the situation of supporting optical focusing control part also can be operated the camera lens that camera section 10 is used, and carries out optical focusing.
Fig. 2 is the flow chart of the execution magnifying function of one embodiment of the invention.As shown in the figure, the user is by key operation, enter the magnifying glass menu of making separately after, multiplying power is set.Above-mentioned multiplying power utilizes optical focusing and numeral focusing to be provided with, and is used for the degree that regulation is amplified.
Then, the object kind that selection will be implemented to observe, this can select one substantially in photo (colour) and document (gray scales of literal and symbol etc.).Ignore or unselected situation under, acquiescence selects preferably photograph image to handle.Wherein, why wanting alternative, is because when making camera near the object of observation, often exceeds the situation of focus limitation, causes the image blurring of the object of observation, and alternative is for this being carried out adequate compensation.That is, as previously mentioned, when being object,, then can obtaining image quality more clearly, thereby further improve the effect of magnifying function if handle image with the gray scale that is bordering on black and white with the document.When being colour, occurring image blurring is that this reason is known already because focus is inconsistent, can use with its handle algorithm more clearly, implement the compensation operation effectively.Even it should be noted that coloured image has been carried out sharpening, do not compare with the situation of passing through the sharpening processing procedure, also can obtain utmost point enlarged image clearly.
It is noted that the time that is provided with, can select multiplying power as shown in the figure equally earlier, but be not to be defined in this, can in Object Selection, carry out, also can carry out at last for above-mentioned multiplying power setting and Object Selection.
In addition, in gray level image is handled,, then can use magnifying glass more efficiently if make the user regulate gamma value (value that the brightness and contrast is regulated simultaneously) by key operation.
And, according to user's selection, can save as photo or activity video through the output picture of the object of observation of above-mentioned amplification and sharpening, keep accurate object observed and recorded.
When using when of the present invention, a kind of magnifying function not only can be provided, that is, provide to the user that will use magnifying glass and to amplify image quality clearly, and, when amplifying the object of observation when taking, also can effectively be used.Therefore, not merely to the user a little less than the eyesight, for the user of the accurate object of observation of needs, this also is a kind of extremely useful function.
As mentioned above, utilization of the present invention is built-in with the mobile communication terminal of camera and realizes that the method for magnifying glass has following effect, promptly, by add other magnifying glass menu at mobile communication terminal, can actively select the optics that mobile communication terminal had and the numeral focusing function of camera function built-in.In order to obtain more distinct image, the user selects one in photo and document after, utilize the different images Processing Algorithm of decision thus, obtain distinct image and amplification, thereby, just can export enlarged image more clearly to the user only by the change on the simple software, so, need not to carry other magnifying glass, also can use enlarged image clearly at any time, improved user convenience greatly.
Above embodiment only is used to illustrate the present invention, but not is used to limit the present invention.
