Embodiment
Referring to Fig. 1, is the block diagram of device for filming image of the present invention.Device for filming image 1 of the present invention as shown in Figure 1, it comprises a filming image module 10, and stores module 11 and a process module 12.It is metal-oxide-semiconductor element (ComplementaryMetal-Oxide-Semiconductor that filming image module 10 at least contains photo-sensitive cell such as complementation, or charge coupled cell (Charge-Coupled-Device, CCD), camera lens and mirror group etc. CMOS); Store module 11 and can be embedded memory body, circumscribed memory card or its combination; Process module 12 is for being electrically connected filming image module 10 and storing module 11, and it can be central processing unit (Central Processing Unit, CPU) or microprocessor (Micro-Processing Unit, MPU).In preferred embodiments more of the present invention, device for filming image 1 can be (Digital Video Camera) such as digital camera (Digital Camera) or digital cameras.
Wherein, filming image module 10 takes multiple temporary image 20, and is stored in storage module 11.One of them of process module 12 setting temporary image 20 is a base image 21, and each temporary image 20 is divided into multiple temporary image block 200, and base image 21 is divided into multiple base image block 210.Process module 12 more judges whether each temporary image block 200 is less than a threshold value 30 with the difference of corresponding base image block 210.When difference between one of them with corresponding base image block 210 of one of them of temporary image block 200 is less than threshold value 30, namely process module 12 carries out image lamination with this temporary image block 200 with corresponding base image block 210, and then corresponding generation one image output 22.Wherein, threshold value 30 at least contains one first threshold value 300 and one second threshold value 301.
In some preferred embodiments, each base image block 210 is more carried out geometric alignment with each temporary image block 200 by process module 12 accordingly, and corresponding calculating one first error amount 31, when the first error amount 31 is less than the first threshold value 300, process module 12 i.e. image lamination base image block 210 and temporary image block 200 accordingly.In addition, in other better embodiment, process module 12 more can utilize stratum's distribution map (histogram) of each base image block 210 and each temporary image block 200, judge whether one second error amount 32 between each base image block 210 and each temporary image block 200 is less than one second threshold value 301, when the second error amount 32 is less than the second threshold value 301, process module 12 i.e. image lamination base image block 210 and temporary image block 200 accordingly.And when one of them and base image block 210 of temporary image block 200 one of them between difference be more than or equal to threshold value time, namely process module 12 carries out luminance compensation to image output 22 in the position corresponding to base image block 210 with digital gain (digital gain) or interpolation method (temporal interpolation).
In some cases, when the situation of the temporary image captured by filming image module 10 is not good, difference between now all temporary image blocks 200 and base image block 210 is all more than or equal to threshold value, then process the brightness that namely module 12 improves base image 21, and beautify to form image output 22 to base image 21.On the implementation, image output 22 is preferably and is stored in storage module 11 with an archives form, and temporary image 20 is stored in storage module 11 with a material form.In addition, image output 22 is preferably and is available for users to viewing, and temporary image 20 cannot allow user watch.
Referring to Fig. 2, is the first embodiment schematic diagram of device for filming image of the present invention.As shown in Figure 2, filming image module 10 have taken three temporary image first continuously, and process module 12 or user and have selected wherein image 23 based on, therefore all the other two are and next will carry out the temporary image 24,25 of geometric alignment with block of cells with base image 23.From in figure, the presentation content of temporary image 25 is too large compared with the disparity of base image 23, its possible reason is that hand shakes the blurring caused, or due to the noise of the too low generation of ambient light illumination too many so that align in the process of geometric alignment out of condition.In the present embodiment, temporary image 25 is for after user's hand shakes, and the situation of the oriented lower vertical displacement of camera produces, so that the sun of top is cut off half, the lake water of below has many images to be taken into.Base image 23, temporary image 24,25 are then divided into multiple block of cells (as shown in broken lines) by process module 12, and carry out block geometric alignment with the pattern of block to block.
Carrying out the process of geometric alignment, such as with temporary image block 240,250 geometric alignment base image block 230, namely process module 12 calculates the geometric transformation parameter of its each temporary image block 240,250 when aliging base image block 230, and process module 12 more produces the first error amount 31 according to each geometric transformation parameter, and compare with the first threshold value 300, if image difference is excessive each other, just correctly cannot align, and then cause error excessive.From in figure, the first error amount 31 that temporary image block 250 produces at geometric alignment base image block 230, due to the Geometry edge difference too large (sun is cut off half) of its image, therefore the first error amount 31 just can more than the first threshold value 300.Now process module 12 and namely assert that this temporary image block 250 is larger with the geometry gap of corresponding base image block 230, image lamination program after not being suitable for, therefore processes module 12 and just temporary image block 250 and base image block 230 can not be carried out image lamination; Contrary, the first error amount 31 that temporary image block 240 produces at geometric alignment base image block 230, because the Geometry edge difference of its image is little, therefore the first error amount 31 just can lower than the first threshold value 300.Now process module 12 and namely assert that this temporary image block 250 is less with the geometry gap of corresponding base image block 230, image lamination program after being applicable to, therefore processes module 12 and just temporary image block 240 and base image block 230 can be carried out image lamination.And one by one carry out block comparison, superimposed after, process module 12 namely create image output 22; But this image output 22 is in the position of base image block 230 owing to having lacked the superimposed of temporary image block 250, and therefore its brightness is not enough.Namely, in the present embodiment, the position of the corresponding base image block 230 of original image output 22 should have the brightness of three opening and closing one-tenth, but now had a temporary image block 250 not have superimposedly to enter, thus the position of the corresponding base image block 230 of image output 22 now after image lamination just only remaining 2/3 brightness.And in order to address this problem, process module 12 is namely with digital gain (digital gain) method, the brightness of the position of corresponding for image output base image block 230 is directly improved 1/3, to reach original user default image brilliance when light-metering.In addition, process module 12 also can interpolation method (temporal interpolation), with the brightness of base image block 230 and temporary image block 240 for benchmark, infer the brightness value of temporary image block 250, and carry out brightness correction according to the position of this brightness value to the corresponding base image block 230 of image output.But should understand person with usual knowledge in their respective areas of the present invention, revise the method for image output brightness and be not only confined to above-mentioned two kinds, these two kinds of methods are only for example and not limitation, chat bright in advance at this.But, under some situation, except base image, when the situation of the temporary image captured by all filming image modules 10 is not good, that is the difference between all temporary image blocks and base image block is all more than or equal to threshold value, then these temporary image then neither can be used to carry out image lamination.Now, namely process module 12 improves the brightness (with digital gain method etc.) of base image, then beautifies to be formed to base image and export this image output.
Referring to Fig. 3, is the second embodiment schematic diagram of device for filming image of the present invention.As shown in Figure 3, first filming image module 10 have taken three temporary image, and process module 12 or user and have selected wherein image 23 based on, therefore all the other two are and next will carry out analyzing with stratum's distribution map (histogram) temporary image 24,25 of presentation content difference with base image 23.From in figure, the presentation content of temporary image 25 is too large compared with the difference of base image 24, because user is in time taking pictures, pedestrian 3 is had to swarm within the scope of the filming image of filming image module 10, so that temporary image 25 is too many in stratum's distribution map 2300 difference of stratum's distribution map 2500 of temporary image block 250 color base image block 230 color corresponding with base image 23, it is different for representing presentation content.Now, process module 12 namely assert the presentation content of temporary image block 250 and comparatively base image block 230 gap is larger, image lamination program after not being suitable for, therefore processes module 12 and namely temporary image block 250 is not carried out image lamination with corresponding base image block 230; Contrary, the presentation content of temporary image 24 is little compared with the difference of base image 24, therefore very nearly the same at stratum's distribution map 2300 of stratum's distribution map 2400 of temporary image block 240 color base image block 230 color corresponding with base image 23 in temporary image 24, it is intimate identical for representing presentation content.Now, process module 12 namely assert the presentation content of temporary image block 240 and comparatively base image block 230 gap is little, image lamination program after being applicable to, therefore processes module 12 and carries out image lamination by temporary image block 240 with corresponding base image block 230.And one by one carry out block comparison, superimposed after, process module 12 namely create image output, and process module 12 also further can carry out luminance compensation according to above-mentioned luminance compensation method to image output, just repeat no more at this.
But, should understand person with usual knowledge in their respective areas of the present invention, judge that the method for each temporary image and base image difference is also not only confined to the independent enforcement of above-mentioned two kinds, also can be its combination, and these two kinds of methods are only for example and not limitation, chat bright in advance at this.
Moreover, control module 12 pairs of temporary image or the segmentation of base image are also not limited to the segmentation of whole image, also can be split in a scope near focusing, or user selects the region of being interested in split on device for filming image, again or in the automatic detecting image of device for filming image independently object (as image after human face recognition the human face region that defines) and to split for object.The present invention does not limit the mode of segmentation temporary image or base image, and user so can be made to have the larger degree of freedom can select the level (namely subregion is superimposed or region-wide superimposed) of its desired image effect exported.
