Abstract
The invention provides a method for reducing an image storage space, which solves the problem of need of a monitoring system for a large storage space for storing an image signal in the prior art. An image processing method comprises the following steps of: (a) acquiring an image signal through a camera; (b) buffering the image signal and outputting a data signal; (c) compressing the data signal and extracting image data of a GIF (Graphic Interchange Format) or JPG (Joint Picture Group) format; (d) comparing the latest image data with the image data, which is updated previously, in a register, extracting the image data of the JPG format and updating the register if a comparison result exceeds a range, and extracting the image data of the GIF format and updating the register if the comparison result does not exceed the range; and (e) storing the updated image data in the register in a memory.
Description
Technical field
The present invention relates to image processing field.
Background technology
Existing household monitoring system needs jumbo memory space to come the memory image signal, because picture signal is too many, needs regularly deletion, has caused great inconvenience.
Summary of the invention
The present invention proposes a kind of reduction image storage space method, solved that supervisory control system needs large memory space to come the problem of memory image signal in the prior art.
Technical scheme of the present invention is achieved in that
A kind of image processing method may further comprise the steps: step (a), obtain picture signal by camera; Step (b) cushions described picture signal outputting data signals; Step (c) is compressed described data-signal, extracts the view data of GIF or JPG form; Step (d), up-to-date view data is compared with the last view data of upgrading in the register, if comparative result has exceeded scope, extract the view data of JPG form, and renewal register, if comparative result does not go beyond the scope, extract the view data of GIF form, and upgrade register; Step (e) is saved in the view data in the register that upgrades in the memory.
Alternatively, the described step that up-to-date view data is compared with the last view data of upgrading in the register is specially: every Fixed Time Interval, up-to-date view data is compared with the last view data of upgrading in the register, finish this compare operation.
Alternatively, described Fixed Time Interval is 0.1 second.
The invention has the beneficial effects as follows: do not have in the discrepant situation at the image that obtains, the image that hangs down pixel is stored in the memory, reduced memory space.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is a kind of flow chart that reduces the image storage space method of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
As shown in Figure 1, a kind of image processing method of the present invention may further comprise the steps: step (a), obtain picture signal by camera; Step (b) cushions described picture signal outputting data signals; Step (c) is compressed described data-signal, extracts the view data of GIF or JPG form; Step (d), up-to-date view data is compared with the last view data of upgrading in the register, if comparative result has exceeded scope, extract the view data of JPG form, and renewal register, if comparative result does not go beyond the scope, extract the view data of GIF form, and upgrade register; Step (e) is saved in the view data in the register that upgrades in the memory.
Alternatively, the step that up-to-date view data is compared with the last view data of upgrading in the register is specially: every Fixed Time Interval, up-to-date view data is compared with the last view data of upgrading in the register, finish this compare operation, for example Fixed Time Interval is 0.1 second.
The invention has the beneficial effects as follows: do not have in the discrepant situation at the image that obtains, the image that hangs down pixel is stored in the memory, reduced memory space.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (3)
