Embodiment 2:
Display methods, as shown in Fig. 2, methods described are imaged the embodiments of the invention provide one kind
Comprise the following steps：
201st, control lens movement n times are shot, and obtain N images.
When implementing, image display device control lens motor drives the lens since the initial value of the focal range, the mobile default step-length, and automatic start shutter is shot after the completion of movement every time, obtains N images.Due to shooting every time all to that should have a focal length, therefore to that should have on different focusings, i.e., every image, most clearly region is different to the N images obtained.The default step-length is N/mono- of the focal range of camera, and the N is the integer more than 1.
202nd, the N corresponding N groups view data of image are stored in corresponding image file.
It is that described image coding is compressed into view data to preserve image under normal circumstances, is then stored in again in corresponding image file.The preservation form of image has JPEG (Jo int Pho t ograph i c Exper t s Group, Joint Photographic Experts Group）, TI FF (Tagged Image F i l e Forma t, TIF）Deng.Example, the image display device carries out JPEG codings to the N images, N group view data is obtained, wherein every image should all have one group of view data.The a view data can be also stored in image file by the image display device.
When the N groups view data is saved in corresponding image file by the image display device, offset of the every group of view data in described image file can be also recorded at the end of described image file, example, the respective offset of N groups view data can be recorded with 8 bytes.If corresponding that group of view data of first image is stored in the original position of described image file by the image display device, then offset of the N-1 groups view data in described image file in addition to corresponding that group of view data of first image can be have recorded at the end of described image file；If corresponding that group of view data of first image is not stored in the original position of described image file by the image display device, then offset of the N groups view data in described image file will be recorded at the end of described image file.Storage form can be with as shown in figure 3, wherein, in the corresponding one group of data of every image of storage, with SO I, (S tar Of Image, image starts）Mark starts, and with E0 I, (End Of Image, image terminates）Mark terminates.
Alternatively, the image display device can also write multifocal photo id symbol in the header of corresponding that group of view data of first image.If screening-mode is set to the shooting step described in the present embodiment 201 in production by the image display device, then each scene that camera is shot is to that should have N images.If the image display device had both supported the screening-mode described in step 201, the screening-mode of general only one of which focusing is supported again, multifocal photo id symbol is write so in the header of corresponding that group of view data of first image, in order to sentence
Whether the photo that breaks is for the captured multifocal photo out of the method that provides of the present invention.
In addition, after the N corresponding N groups view data of image are stored in image file by the image display device, the corresponding view data of image that user chooses can also be obtained according to the demand of user, so that other equipment can be shared to by described image Data Data by obtaining user.I.e. user can select an image according to the hobby of oneself in the N images, the image display device obtains the corresponding offset of this image according to the operation of user, and view data is obtained in image file according to this offset, so, the view data of the image can be just sent to other equipment by user.Or, the image file on the camera can be transferred on other display equipment, so that user selects image on the other display equipment according to hobby, obtain the corresponding view data of the image and send it to kith and kin.Example, the N images can be shown on computers, when user chooses one according to hobby in the N images, when user clicks on the image, offset of the image in described image file is just obtained inside computer, then described image file is accessed according to the offset, it is possible to obtain the corresponding view data of the image, it is possible to give other kith and kin by described image data forwarding.
2 03, the N group view data in described image file is converted into N number of bitmap file, and preserves N number of bitmap file.
When the N groups view data is converted into N number of bitmap file by the image display device depending on the preserving type to the N groups view data described in step 2 02.If corresponding that group of view data of first image preserves the original position of described image file, and the end of described image file have recorded offset of the 1 group of view data of N- in described image file in addition to corresponding that group of view data of first image, then the image display device reads first group of view data in the original position of described image file, and the offset in the end position of described image file reads each comfortable described image file of 1 group of view data of remaining N-, then corresponding view data is read in described image file according to the corresponding offset of each group view data.Afterwards, the N group view data read is converted into bitmap file by the image display device again.Or, if corresponding that group of view data of first image does not preserve the original position of described image file, and the end of described image file have recorded offset of the N groups view data in described image file.So, the image display device reads each self-corresponding offset of N groups view data at the end of described image file first, then the N groups view data is read in described image file according to respective offset, the N groups view data is converted into bitmap file again afterwards, and is stored in internal memory.
2 04, the corresponding image of any bitmap file in N number of bitmap file is shown.
Generally, the image display device acquiescence shows first in N images.If
The image display device only supports the screening-mode described in step 2 01, multifocal photo id symbol can not be carried in the header of corresponding that group of view data of so first image, at this moment the image display device shows that the corresponding image of any bitmap file can in N number of bitmap file.If the image display device not only supports the screening-mode described in step 2 01 also to support general exposal model, it is accomplished by carrying multifocal photo id symbol in the header of corresponding that group of view data of so first image, at this moment, the image display device acquiescence shows first in N images.
2 05, judge whether the header of the corresponding view data of corresponding first image of image file carries the multifocal photo id symbol.
If carrying, step 2 06 is carried out, if not carrying, the corresponding image of view data is directly displayed.
2 06, the image switching command of user's input is received, described image switching command carries rectangular coordinates value.
Wherein, the rectangular coordinates value represents a region on the image of display.In fact, when user clicks on a region on the image that camera is currently shown, camera internal just generates one and carries user's click on area（User requires the region of display）Rectangular coordinates value image switching command, correspondingly, camera internal can just receive described image switching command.In this manner it is possible to according to the demand display image of user, to improve Consumer's Experience.
Here, image one focusing of correspondence that the image display device is currently shown, that is, have a region to be apparent from.When user clicks on other regions of the image currently shown, an image switching command will be automatically generated inside the image display device, and the rectangular coordinates value that user requires the region of display is carried, so that the image display device is switched over according to the demand of user to image.
2 07, relatively more described N number of bitmap file is worth the definition in corresponding region in the rectangular coordinates, obtains the rectangular coordinates and is worth the maximum bitmap file of corresponding region definition.
Carry out definition of the N bitmap file described in comparison in the corresponding region of the rectangular coordinates value using definition algorithm, with the image that the definition for obtaining the corresponding region of the rectangular coordinates value is maximum.
Example, definition is calculated using the definition algorithm based on gray variance.The definition evaluation of estimate in the region is calculated for the corresponding region of the rectangular coordinates value on each bitmap file, wherein, described=1/MN Z Z
Uj, described M, N are the height and width of a certain pixel, and described/(x, _ y) shouldxAs the coordinate value at sight spot（X, y) corresponding gray value, the ^ is currently the average gray value of the image.Calculating the definition evaluation of estimate of N number of bitmap file
When, just obtain N number of value.Wherein, the corresponding bitmap file definition of maximum value is maximum.As described in step 201, due to having carried out n times shooting using different focal, therefore same region on N images definition be different.The image display device is worth the definition in corresponding region by N more all bitmap file of definition algorithm in the rectangular coordinates, it becomes possible to obtain the bitmap file for being worth the definition maximum in corresponding region in the rectangular coordinates.
208th, the maximum corresponding image of bitmap file of the definition is shown.
At this moment, the corresponding image of bitmap file of the definition maximum shown on the image display device is exactly the maximum image of user's click on area definition.The image display device switches image according to user's request, improves Consumer's Experience.In addition, user can also obtain any in the N image according to hobby.
