Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
Consult Fig. 1, Fig. 1 is that the present invention utilizes motor continuous moving to generate the schematic flow sheet of method first execution mode of same scenery different focal.The step of the method comprises:
S101: in the focus process of shooting, according to data or the current data continuous moving focusing motor obtained of preset focusing parameter list, and in the different motor shift positions of focusing parameter list or the current data defined obtained, corresponding different photo is obtained to same reference object until complete and focus and take, preserve photo, focusing parameter list and the current packet obtained contain the different motor mobile position datas of corresponding different focal.
The focus process of shooting alleged here, refer to a focus process of capture apparatus such as camera terminal, in this time focus process, instruction that first capture apparatus accepts " focusing ", such as common " focusing " instruction of partly pressing " focusing " button and triggering, then capture apparatus controls the focusing motor running of camera lens or fuselage according to " focusing " instruction, and the focal length that eyeglass in camera lens is formed changes, until capture apparatus obtains enough this processes of imaging clearly.In prior art this time in focus process, although the photo-sensitive cell of capture apparatus is obtaining photo always, but before not focusing successfully, these photos got all are given up, until focus successfully, just the photo reservation of the successful that time of focus, that is only have the photo under successfully obtained focal length of focusing just can be considered to universal significance " is taken pictures ", and the photo that before focusing successfully, photo-sensitive cell obtains all is given up, the photo that these are given up for user is invisible.
In embodiment of the present invention, the data of the preset focusing parameter list of camera terminal, manually will debug according to the performance of terminal focusing motor time preset.The step number of motor movement is set at random by user during debugging, by display screen observation effect, when obtaining satisfied effect, preserves the motor this time arranged and move step number.Repeatedly debug, preserve multiple motor and move step number and generate focusing parameter list.In the focus process of terminal taking, the focusing parameter list preset can be called.Also or camera terminal in daily shooting process, use at most when user takes pictures by terminal or obtain image the most clearly focal position data be kept in the system of terminal, for the present invention, this i.e. aforesaid " the current data obtained ".But when considering that user takes pictures, usually the focal length of each object in scene can not be obtained one by one, and parameter list of focusing is through specialty and measures and obtain, therefore suggestion uses focusing parameter list, will obtain the mobile location information of focusing motor in the present embodiment from focusing parameter list.
Focusing motor, according to the data mobile in focusing parameter list, when arriving the focal position of focusing parameter list setting, takes corresponding photo, and the photo namely under photo-sensitive cell reservation this focal position corresponding, does not give up.Until the different motor shift positions of all corresponding different focal of focusing motor traversal after take, comprising focus retains the photo of focus lock successfully, stop taking and moving, by all photos preservations photographed.
In a concrete application, user carries the motor sensor performance of camera according to photographer, such as the step number of focusing parameter list focusing motor movement is set to be 170,190,208,228,260,312,392,508,582 these 9 numerical value.Quantity of taking pictures will to move the quantity of step number identical with focusing motor in focusing parameter list.Current is shooting 9 photos, corresponds respectively to different preset motors and moves step number.After having taken, 9 photos obtained are preserved.
S102: find each same designated area image the most clearly in all photos, by the number record in the corresponding region in photo of image the most clearly, to generate the list recorded and number corresponding to each apparent region.
All photos of shooting gained are contrasted, often will open photo during contrast and specify multiple region all in an identical manner, give different numbering to all photo appointed areas.Be numbered 1 as given in S101 the photo preserved, 2 ... 9, often open photo appointed area be numbered A, B ... H, I ...Comprehensive two kinds of numberings, there is the numbering of " numeral-letter " form each appointed area of all photos, and each numbering is not identical.For guaranteeing to obtain image clearly, often opening region that photo specifies can not very little, and the things of the shooting of multiple focal lengths of the parameter list regulation that had better not make to focus in S101 falls in a region, and impact judges.Just compare between all photos of the same area, obtain image and corresponding region numbering thereof the most clearly, generate this numbering of list records.The number of pictures of such as preserving is 9, and during contrast same designated area, the region quantity of contrast can be arbitrary value, in the present embodiment, appointed area is divided into 9.Finally obtain 9 different images the most clearly and 9 numberings, be recorded in clear list.
S103: integrate photo and list.
After comparative analysis completes in S102, the list packing of photo after treatment and generation is preserved, facilitates subsequent treatment.In concrete operations, the analytic process in S102 may need just can carry out subsequent operation by after the format conversion of the photo preserved in S101, does not need to be changed by photo form during preservation again, only need preserve by the form of the converted photo of S102.
Be different from prior art, the present invention takes pictures respectively in focus process in different focal situation, obtains the different photos under different focal, can prevent photographer from missing the best and find a view opportunity; Utilize focusing motor continuous moving, at different focal place, obtain corresponding photo to same reference object, not simple continuous shooting, can capture the interested things of some cameramans in same coverage in shooting process; After obtaining photo, to analyze in the identical appointed area of all photos part the most clearly, the instrument analyzed here is through the algorithm of programming and obtaining, and analytic process is rigorous, but not goes inference analysis with subjectivity; Most picture rich in detail reference numeral is generated list, and leads to packing with photo one and leave assigned address in, conveniently reuse and and subsequent treatment.
Consult Fig. 2 and Fig. 3, Fig. 2 is that the present invention utilizes motor continuous moving to generate the schematic flow sheet of the second execution mode of the method for same scenery different focal, and Fig. 3 is that the present invention utilizes motor continuous moving to generate the schematic diagram that in method second execution mode of same scenery different focal, photo is split in the same manner.The concrete steps of this photographic method comprise:
S201: in the focus process of shooting, sends to focusing motor controller, to control focusing motor continuous moving at focusing motor controller the mobile step count information of focusing motor in focusing parameter list or the current data obtained.
In the process of shooting focusing, camera terminal obtains the information that focusing motor moves step number from the data that preset focusing parameter list or take before obtains, and during preset focusing parameter list, operation is identical with the operation in first embodiment of the invention.Focusing motor is moved step count information and send to focusing motor controller, usually send in the mode of SendCommand order.Focusing motor controller receives this SendCommand order, moves step count information, control focusing motor continuous moving by Icotl mode according to focusing motor in order.Ioctl is the hardware controlling method of a kind of standard of linux, can control focusing motor accurately and move.
S202: focusing motor gives up the image that camera lens obtains when the focusing position that non-focusing parameter list or the current data obtained specify.
Focusing motor controller, in focusing motor moving process, can send message to continuous shooting controller, and the photo taken when not arriving the focusing position that focusing parameter list or the current data obtained specify in focusing motor given up by continuous shooting controller.Because do not arrive focusing parameter list or the current data obtained specify focusing position time, the photo obtained is that the present invention institute is unwanted, and when certain frequency shooting pressed by continuous shooting controller, the quantity of this kind of photo can be very huge, committed memory, main is affect subsequent terminal to distinguish the photo that the focal length of focusing parameter list setting is corresponding.Focusing motor enters S203 after arriving the focal position of specifying.
S203: the different motor shift positions arriving focusing parameter list or the current data regulation obtained obtain corresponding different original photo to same reference object.
Focusing motor arrives the motor shift position of each regulation, and the camera lens of continuous shooting controller obtains the photo of relevant position, and photo-sensitive cell retains the photo under this focal position corresponding, does not give up.Then focusing motor moves to next preset focal position, if the preset focal position of focusing motor is not still covered, returns step S201, otherwise enters S204.
S204: what original photo was converted to the first photo form turns form photo, and the luminance parameter produced when turning form is as photo parameter.
What original photo converted the first photo form to turns form photo, and the first photo form can be yv12 form, and the photo of yv12 form is compared with original photo, and luminance signal remains unchanged, and carrier chrominance signal reduces by half.The data of luminance parameter can be extracted preservation by the photo simultaneously converting the first photo form to, and luminance parameter refers to the luminance signal data of image, is often designated as Y data, and these data are photo parameters is follow-up important evidence of carrying out when image comparison is analyzed.
S205: by the first photo form turn that form photo is converted to the second photo form turn form photo, that preserves the second photo form turns form photo and luminance parameter.
Second photo form can be Jpeg form, the photo of Jepg form has superiority in image procossing, and the range of application supervening the first form photo of luminance parameter during conversion is little, and need specific picture instrument just can open, be unfavorable for preservation and the preview of photo.
S206: each photo is divided into multiple region with partitioning scheme of the same race, and sequentially numbers for regional.
By the identical partitioning algorithm segmentation of all photos, be only by the picture segmentation of photo herein, the not image segmentation algorithm of digital image processing field.Partitioning scheme is made by oneself, but need ensure that the shape having split rear all photo the same areas is identical.Give all zone numbers after having split, the mode of numbering is identical with the numbering in execution mode in the present invention first.As shown in Figure 3, in the particular embodiment, S205 obtains 9 Jepg form photos after turning form, and these 9 Jepg form photos are partitioned into 12 zonules with identical partitioning scheme.Be numbered 1 to 9 Jepg form photos, 2 ... 9, give often open 12 zonules that photo is divided into by the serial number shown in Fig. 3 be A, B ... L.Therefore, each region of often opening photo has independently numbers, and if first photo, first zone number is 1-A, the 9th zone number of the 6th photo is 6-I.
S207: each same designated area analyzing all photos according to luminance parameter, and for each same designated area, in all photos, to filter out in same designated area the region of most picture rich in detail, record the numbering in the region of most picture rich in detail to generate the list recorded and number corresponding to each apparent region.
Analyzing will with reference to the luminance parameter of aforementioned preservation when contrasting.In the present invention, luminance parameter is Y data, is one of condition judging image definition.According to luminance parameter Y parameter, comparative analysis obtains appointed area image the most clearly, and number record corresponding for this region is kept in a newly-generated clear list.As in the L region, the 12nd region of 9 Jepg form photos, the L region through contrast discovery the 8th photo is the most clear, is just kept in the clear list of generation by the numbering 8-L in the L region of the 8th photo.12 numberings can be preserved in the final clear list of present embodiment.
S208: integrate photo and clear list.
What preserve is final turn in form photo and S207 through Jepg form after format conversion the clear list generated herein, the two file be saved as certain special format is positioned in the file system of terminal, is applied accordingly carry out follow-up work by camera terminal.
Said method, terminal inner mutual, by the transmission of instruction, finally obtaining the photo of different focal and record the list of most clear area numbering, is subsequent operation, as the application such as to take pictures of rear focusing and full focal length provides Data support.
