Abstract
The present invention relates to a method and a device for sampling a dynamic image. The present invention uses the character that the dynamic image displays fixed picture numbers per second, and the correlations of the picture numbers and shooting seconds are converted. Users can define sampling frequency itself, and at least one sampling picture is taken out according to the sampling frequency. The sampling picture is converted into a static image according to set output formats, and the static image is stored in an independent file comprising at least one sampling picture; the static image can be directly output to form a picture or can be edited and used by image edition software.
Description
Technical field
The method and apparatus of the relevant a kind of sampling dynamic image of the present invention is particularly about a kind of method and apparatus that is applied to the sampling dynamic image in the digital camera.
Background technology
In recent years because digital development of science and technology, image changes dynamic storage into by the storage of static state, when image is developed into when dynamic by static state, for observing action details and for example player's posture correction of action of comparing mutually in a plurality of dynamic images in the dynamic image, best method promptly is dynamic image to be converted to static image handle, and the method and apparatus that therefore dynamic image is converted to static image just becomes indispensable.Dynamic image is stored in the tape in the past, can only be during details in observing dynamic image by the fast commentaries on classics rewinding of videocorder, broadcast and time-out are observed, not only observe and be difficult for but also dynamic image can't be converted to static image output observing comparison, even dynamic image stores with digital signal now, also File Format difference because of storing, dynamic image need be handled through complicated software and hardware just can be converted to static image output, can't when taking dynamic image be converted to static image observes and stores, even present most digital camera has only broadcast and suspends two kinds of Presentation Functions for dynamic image, there is not the function that other is handled at dynamic image, it has similar dynamic image and is converted to static image merit able one and is detected in a digital camera that olympus was once produced, but it can only produce fixing picture (frame) number and watch on the display screen of digital camera, can't carry out static image output, and when the time that dynamic image carries out is long slightly, the picture interval time is also elongated relatively, and function is still incomplete for the user.Therefore, a kind ofly can set up sampling frequency on their own, and dynamic image can be converted to the method and apparatus of the high efficiency sampling dynamic image of static image output by the user.
Summary of the invention
One of purpose of the present invention is to provide a kind of method and apparatus of sampling dynamic image.
Two of purpose of the present invention, other is to provide a kind of more convenient digital camera to handle the method and apparatus of sampling dynamic image.
For achieving the above object, the present invention proposes a kind of method of sampling dynamic image, this dynamic image is made of in time in regular turn a plurality of continuous pictures, comprise the following steps: the convert number of described picture and the relevance between the shooting second number, this relevance is to show that according to the dynamic image per second characteristic of fixed image number determines; The user sets up sampling frequency on demand on their own, takes out at least one sampling picture according to this predefined sampling frequency from this dynamic image; And the picture of should taking a sample is converted to static image output according to a predefined output format.
The invention allows for a kind of device of sampling dynamic image, this dynamic image is made of in time in regular turn a plurality of continuous pictures, and this device comprises: a buffer, in order to store this dynamic image; One buffer is in order to provide sampling frequency and output format; An and processor, in order to calculate the number of pictures in this dynamic image and to take relevance between second number, the user sets up sampling frequency on demand on their own, from this dynamic image, take out at least one sampling picture according to this sampling frequency, and the picture of should taking a sample is converted to static image according to this output format, and the static image after the conversion is exported.
According to the present invention, a kind of method of sampling dynamic image, utilize the dynamic image per second to show the characteristic of fixed image (frame) number, the number of this picture and the relevance between the shooting second number convert, the user can define sampling frequency (sampling frequency) voluntarily, take out at least one sampling picture according to this sampling frequency, this sampling picture is converted to static image according to the output format of setting, and this static image saved as independent archives and wherein comprises at least one sampling picture, this static image can be directly output as photograph or by video editing software for example PhotoShop edit and use.
According to the present invention, a kind of device of sampling dynamic image comprises a buffer, in order to store dynamic shadow image; One buffer is in order to sampling frequency and the output format that setting is provided; One processor, in order to calculate the number of pictures in this dynamic image and to take relevance between second number, take out at least one sampling picture according to this sampling frequency, this sampling picture is converted to static image according to the output format of this setting, and stores independently archives in order to output or editor this static image; And one second buffer, in order to store this sampling picture and this static image.
Method and apparatus of the present invention has only the display mode of continuous broadcast and time-out for dynamic image in the present digital camera, provides more complete function more obvious when especially action details and a plurality of continuous action picture are observed simultaneously in observing dynamic image.

Embodiment
According to the present invention, the method 10 of one sampling dynamic image as shown in Figure 1, wherein a dynamic image 11 is made up of in regular turn in time as the user a plurality of pictures and is set a sampling frequency, according to this sampling frequency by taking out a plurality of sampling pictures 12 in this dynamic image, these a plurality of sampling pictures are converted to static image output according to the output format of setting, this output format can be 1 * 2,2 * 2,2 * 3 or other form, looking user's demand stipulates voluntarily, when the setting output format is 1 * 2, each static image 13 comprises two sampling pictures, if being set at 2 * 2 each static images 14, output format comprises four sampling pictures, similarly, when output format is set at 2 * 3, each static image 15 comprises six sampling pictures, each static image all save as independent archives and wherein comprise at least one the sampling picture, can be directly output as photograph or by video editing software for example Photoshop edit and use.
Fig. 2 is the device 20 of a sampling dynamic image, comprises a buffer 22 in order to store dynamic image; Sampling frequency and the static image output format of one buffer 24 in order to setting to be provided; One processor 26 is in order to calculate the number of pictures in this dynamic image and to take relevance between second number, the user sets up sampling frequency on demand on their own, take out the sampling picture according to the sampling frequency of this setting, and the picture of will taking a sample is converted to static image according to the output format of setting, and the static image after the conversion is exported.
The device 20 of above-mentioned sampling dynamic image more comprises one second buffer 28 in order to store sampling picture and static image.
Fig. 3 is a dynamically flow process 30 of sampling, at first importing a dynamic image 31 then calculates the number of pictures in this dynamic image and takes relevance 32 between second number, the user sets sampling frequency 33 on demand and takes out sampling picture 34 according to sampling frequency subsequently, this sampling picture is converted to static image 36 according to the output format of setting 35, and this static image 36 can be one or more archives output.
