Image storage method of the present invention is the electronic installation that is used for various tool memory cell, as image capturing device, image capturing device for example is digital camera (Digital Camera, DC), digital camera (Digital Video, DV), digital videocorder (Digital Video Recorder, DVR) or digital detecting system (Surveillance System).By preestablishing a critical value, when the store status of memory cell reaches critical value, electronic installation promptly automatically dwindles the image resolution ratio of the previous image of storing of memory cell or image is compressed, with the data volume of image in the reduction memory cell, and then increase operational memory space relatively.
First embodiment
The image that image capturing device captured can be stored in the memory cell with different images resolution (Resolution) such as 2048 * 1024,1024 * 768,800 * 600 or 640 * 320.In other words, along with the difference of picture size, image is also inequality in the data volume size of memory cell.In general, if when image is stored in memory cell with 2048 * 1024 image resolution ratio, its shared memory space is about 1-2Mbyte.And if identical image changes when being stored in memory cell with 1024 * 512 image resolution ratio, its shared memory space is about 0.25-0.5Mbyte.
Hence one can see that, and the shared memory space of different image resolution ratios is promptly inequality.For fear of inconvenience and the puzzlement that the deleted image data are brought, the image storage method of present embodiment memory capacity be about to saturated before, automatically change the resolution sizes of image, to increase operational memory capacity.
Please refer to Fig. 2, it shows the flow chart according to the image storage method of first embodiment of the invention.The image storage method of present embodiment comprises the steps: that at first shown in step 210, electronic installation is stored to memory cell with image with first image resolution ratio.For keeping the display quality of image, first image resolution ratio for example preferably advises being set at the optimum resolution of electronic installation.For instance, if the optimum resolution of electronic installation is 2048 * 1024, then first image resolution ratio preferably is set at 2048 * 1024.
Then shown in step 220, electronic installation shows that a parameter setting picture requirement user imports a parameter accordingly according to this image.The user can import a parameter according to own favorable rating to this image, as
Or
Deng.And before the picture size of image was not dwindled, the user can change the parameter size at any time, the picture size size after dwindling with adjustment.
For instance, if the user likes this image very much, the bigger mark of then corresponding input as
On the contrary, if the user thinks that the importance of this image is not high, the less mark of then corresponding input as
Therefore, every image in the electronic installation, the user can both comply with own favorable rating difference, gives different parameter values.
And then shown in step 230, the picture number of storing along with memory cell is many more, and the residue memory capacity of memory cell is few more, and electronic installation will judge whether the store status of memory cell is about near saturated.
At last shown in step 240, when the store status of memory cell during near a critical value, electronic installation automatically is reduced into second image resolution ratio with image by first image resolution ratio according to the parameter that previous user sets, to reduce image shared memory space in memory cell.Critical value is for example for the residue memory capacity of memory cell, residue memory capacity percentage, store data capacity or stored data capacity percentage.For convenience of description, the critical value of following content is that the data capacity of the storage percentage with memory cell is the example explanation.
For instance, if critical value is 90%, and first image resolution ratio of image is 2048 * 1024, and the user is set to the parameter of this image
When the data capacity of the storage percentage of memory cell near 90% the time, electronic installation promptly automatically is reduced into 1024 * 512 according to parameter with the image in the memory cell, make image in memory cell, take up space and be reduced to 1/4th, to have increased operational memory capacity in the memory cell accordingly.
Hence one can see that, when all images in the memory cell all with parameter during minification, its memory capacity of saving will be more considerable.Before for example picture size was dwindled, the data capacity of the storage S of memory cell equaled
N is a positive integer, and R (n) is the data volume of each image.After picture size was dwindled, the data capacity of the storage S ' of memory cell equaled
And C (n) is the minification of each image.Memory cell increases the memory space of (S-S ') promptly after picture size is dwindled accordingly.
The size of the above-mentioned critical value and first image resolution ratio also can be set at the default value (Default Value) of electronic installation except that can being imported by the user, to increase the operational convenience of user.
Please be simultaneously with reference to Fig. 3, Fig. 4 and Fig. 5, Fig. 3 shows the schematic diagram of critical value setting picture.Fig. 4 shows the schematic diagram that first image resolution ratio is set picture.Fig. 5 shows the schematic diagram of parameter setting picture.
If critical value, first image resolution ratio and parameter are when being imported by the user, the user also can see through the mode of selecting except that the input digit size, the size of decision critical value, first image resolution ratio and parameter.
In Fig. 3, the critical value setting picture provides 98%, 95%, 90%, 88%, 85% or 80% 6 option.When the user select 90% and press determine after, critical value promptly is set at 90%.When the store status of memory cell near 90% the time, electronic installation is promptly according to the resolution sizes of parameter change image.
And as among Fig. 4, first image resolution ratio is set picture 2048 * 1024,1024 * 768,800 * 600 or 640 * 320 4 options is provided.When the user select 1024 * 768 and press determine after, first image resolution ratio promptly is set at 2048 * 1024.Image capturing device is promptly stored this image to memory cell with 2048 * 1024 image resolution ratio behind capturing images.
