Fig. 1 is the composition structural drawing of a kind of image processing apparatus first embodiment of the present invention;
Fig. 2 is the composition structural drawing of a kind of portable terminal device first embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
With reference to Fig. 1, show the composition structural drawing of a kind of image processing apparatus first embodiment of the present invention.Described image processing apparatus 100 comprises image input block 110, selected cell 120, image zoom unit 130 and at least one object element.For the convenience that technical solution of the present invention is described, below described at least one object element among each embodiment describe with display unit 140 and storage unit 150 these two object elements, it will be appreciated by those skilled in the art that, described at least one object element of the present invention is not limited in described display unit 140 and storage unit 150 these two object elements, for other object element, be applicable to the present invention too.
Described image input block 110 is used to import original image.
Described selected cell 120 is used for selecting one or more object outputs as described image zoom unit 130 of described at least one object element.
In the present embodiment, described selected cell 120 is selected described display units 140 or described storage unit 150 object output as described image zoom unit 130, and what promptly described image zoom unit 130 will be according to described selected cell 120 selected object elements (as display unit 140 or storage unit 150) carries out convergent-divergent to original image.
A described image zoom unit 130, the requirement that is used for the object element selected according to convergent-divergent algorithm and described selected cell 120 is scaled to the original image of described image input block 110 inputs and meets the image that object element that described selected cell 120 selects requires size, and exports scaled images to object element that described selected cell 120 is selected.
The convergent-divergent algorithm that described image zoom unit 130 is adopted is a prior art, and the embodiment of the invention is not described in detail this, gets final product with reference to the associated description of prior art.
If described selected cell 120 has been selected display unit 140, then described image zoom unit 130 requires the convergent-divergent original image according to display unit 140, and exports scaled images to described display unit 140; If described selected cell 120 has been selected storage unit 150, then described image zoom unit 130 requires the convergent-divergent original image according to storage unit 150, and exports scaled images to described storage unit 150.

Being example with preview mode, Photographing Mode, image pickup mode respectively below describes the concrete course of work and the principle of work of portable terminal device 200 of the present invention.
One if preview mode:
Then image zoom unit 130 zooms to the size of the image that display unit 140 will show with original image, and exports scaled images to described display unit 140 and show, so that the user carries out preview.
Two if Photographing Mode:
1, then image zoom unit 130 zooms to original image the size of the image that display unit 140 will show earlier, and exports scaled images to described display unit 140 and show, so that the user carries out preview.
2, after the user triggered the order of taking a picture, then image zoom unit 130 zoomed to original image the size that storage unit 150 is wanted memory image again, and exported scaled images to described storage unit 150 and store.
Three if image pickup mode:
1, then image zoom unit 130 zooms to original image the size of the image that display unit 140 will show earlier, and exports scaled images to described display unit 140 and show, so that the user carries out preview.
2, after the user triggered shooting order, then image zoom unit 130 zoomed to original image the size that storage unit 150 is wanted memory image again, and exported scaled images to described storage unit 150 and store.
Follow repeating step 1 and step 2, the shooting that continues.
The present invention is kept to an image zoom unit with a plurality of image zooms unit, selection by selected cell makes a described image zoom unit satisfy the image zoom that the different target unit requires equally, owing to only adopted an image zoom unit, reduced the design difficulty of chip, reduced the size of chip, save the shared storage space of convergent-divergent algorithm, reduced the manufacturing cost of chip.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
