Abstract
The present invention is technology of maintaining the instantaneous changing information, including wink, hand vibration, expression, etc. while taking still image with a camera. The present invention consists of following three processes: the first capture process of still images in, before and after any instant; the second process of measuring the similarity of the three images, distinguishing some frames capable of being discarded before encoding and determining resolution and encoding target area based on the frames to be encoded; and the third process of encoding the previous distinguished frames and areas of the three said images.
Description
Technical field
The present invention relates to a kind of technology of preserving the image information of rest image before and after taking constantly when the camera rest image simultaneously, is a kind of camera stationary pictures catching method that can generate the image file of moment property change informations such as nictation of including the rest image moment, hand swing, expression shape change.
Background technology
Fig. 1 is the block diagram that utilizes the camera stationary pictures acquisition equipment of conventional art.As shown in the figure, it is that unit preserves required frame memory (12), the image signal encoding by above-mentioned frame memory (12) output is processed into the required image encoder of established form (13) formation with the frame by the required camera of photographic subjects subject (11), the picture signal of utilizing above-mentioned camera (11) to take, 2 its effects of explanation with reference to the accompanying drawings.
When the user utilizes camera (11) (TO) takes subject as shown in Figure 2 at any time, press soon behind the door, the picture signal that take this moment is stored in the frame memory (12) temporarily, and image encoder (13) is processed into established form and output to the image signal encoding from frame memory (12) output.
Therefore, the user plays and passes through the as above image file of treatment step output, after showing in display device, if find nictation or hand swing etc., needs in case of necessity to take again.
In this camera stationary pictures catching method that utilizes conventional art,, therefore there is the defective that at all can't discern the subtle change of moment owing to only handle 1 a frame rest image signal and the output of taking at any time.
Summary of the invention
For this reason, the purpose of this invention is to provide a kind of camera stationary pictures catching method, when preserving the respective stationary image information, moment property change informations such as the nictation of preservation rest image moment, hand swing, expression shape change.
Camera stationary pictures catching method of the present invention is made of following three steps: first step be captured in simultaneously any time (TO) catch shooting rest image and with this be constantly benchmark before this, after this constantly (TB), image (TF); Second step measure above-mentioned 3 moment (TB, TO, the similar degree between the image of TF) catching, the frame that differentiation need not be encoded and just can be given up is at frame decision resolution and the coded object zone that will encode; Third step is to (TB, TO carry out encoding process to frame and the zone as above distinguished in picture frame TF) in above-mentioned 3 moment.

Embodiment
Fig. 3 is a camera block diagram of using still image capturing method of the present invention.As shown in the figure, it by the required camera of photographic subjects subject (31), the 1 frame rest image signal of taking at any time and before this/after this picture signal of frame be processed into set form and be that unit preserves required frame memory (32), the image signal encoding by above-mentioned frame memory (32) output is processed into the required image encoder of established form (33) constitutes with the frame, the of the present invention effect of 4 to 8 detailed descriptions with this kind structure with reference to the accompanying drawings.
When the user utilizes camera (11) (TO) takes subject as shown in Figure 2 at any time, press soon behind the door, the picture signal that take this moment is stored in frame memory (12) temporarily, and image encoder (13) is processed into established form and output to the image signal encoding from frame memory (12) output.The user utilizes camera (31) when taking subject at any time, press soon behind the door, as shown in Figure 4, with TO is benchmark constantly, take before this (TB), (TF) totally 3 frames after this, the picture signal that catch this moment is formatted into an image file as shown in Figure 5, is stored in frame memory (32) temporarily.
In above-mentioned Fig. 4, before this (TB), after this moment of (TF) is the value that can be regulated by the user.In above-mentioned 3 moment (TB), (TO), when (TF) bit stream of the image of Pai Sheing is saved in frame memory (32), preserve TO bit stream constantly earlier, and then preserve TB, TF bit stream constantly, so just can keep compatibility with the captured image file of common image taking method.
And, multiple handle can be arranged in above-mentioned 3 moment (TB), (TO), (TF) image of Pai Sheing is saved in the method for frame memory (32).For example, for the image of taking constantly at TO, can use rest image compress mode (in the frame of example: JPEG, MPEG (Intra-frame)), for the image of taking constantly at TB, TF, can use mode based on the frame-to-frame correlation in rest image compress mode or the mobile compression of images mode.
In addition, Fig. 6 a to 6c is other embodiment at above-mentioned Fig. 4, has promptly shown handle in above-mentioned 3 moment (TB), and (TO), (TF) image of Pai Sheing is stored in the method for frame memory (32).
The example of Fig. 6 a is to preserve with the resolution (resolution) that is different from the image of taking constantly at TO at the image that TB/TF takes constantly.
Fig. 6 b is a part that is only limited to the image of taking constantly at TO at the image that TB/TF takes constantly and preserves.In this case, as when wanting to be presented at all images that TB or TF take constantly, then the image of taking constantly at TO as end picture, be superimposed upon image that TB or TF take constantly thereon and show and get final product.
Fig. 6 c is a part that only limits to the image taken constantly at TO at the image that TB/TF takes constantly and preserves, and simultaneously, preserves with different resolution.
In Fig. 4 and Fig. 6, Δ B, Δ F are the time values that is provided with for the moment property subtle change that detects TO rest image constantly, are traditionally arranged to be less value, have very high correlativity between TB, TO, TF image constantly.Therefore, as the similar degree measurement result, when the similar degree of TB, TO, TF image constantly is very big, simply can ignore particular frame.For example, as the similar degree measurement result, when the similar degree value of TB, TO image constantly is very big, then do not need to preserve TB image information constantly.
As a result, according to similar degree measured value and user's hobby, with a kind of method in the rest image store method of above-mentioned Fig. 4, Fig. 6 a-6c preserve above-mentioned a series of catch image after, by image encoder (33) encoding process become established form and output.
Fig. 7 is the formative example of the image bitstream of taking constantly at above-mentioned TB, TO, TF.
As the above-mentioned detailed description of doing, the present invention can be the 1 frame rest image signal of taking at any time and before this, after this picture signal of frame is processed into set form and output simultaneously, so has the effect of moment property variations such as the nictation that can confirm the rest image moment, hand swing, expression shape change.
