The pending picture is filtered using high pass wave band (such as medium filtering), enhancing is described pending
The high-frequency signal at the edge of picture, remove the noise in the pending picture, reach make it is described pending
The part obscured in picture is apparent from.
Further, the pending picture is sharpened using image sharpening method can be by following
A kind of mode is realized：The edge of the pending picture is extracted using edge extraction techniques, then according to being carried
The profile of pending picture described in the edge compensation taken, increase the edge of the pending figure.
When it is severe that the picture processing system 10, which determines the fog-level of the pending picture, due to
Image can not be corrected, prompt pending picture described in user not correct, and prompt user to clean
The eyeglass of the picture pick-up device 40.
In other embodiments, after the contrast in calculating the pending picture per sub-regions,
The picture processing system 10 obtains the pending figure according to the contrast of calculated every sub-regions
Minimum contrast corresponding to piece, when minimum contrast corresponding to the pending picture is less than the 3rd preset value
When, and minimum contrast corresponding to the pending picture is stored in the storage device 20.Work as place
When managing other pictures, equally when minimum contrast corresponding to other described pictures is less than the 3rd preset value
When, and other described pictures are corresponded into minimum contrast and are stored in the storage device 20.When default
Between in section, when the number of the minimum contrast of the storage device 20 storage is more than predetermined number, prompting
User cleans the eyeglass of the picture pick-up device 40.3rd preset value, predetermined number are empirical value.
Therefore, the present invention according to the fog-level of the pending picture to the pending picture at
Reason, so as to improve the definition of blurred picture, and user can be prompted when picture blur degree is severe
Eyeglass is cleaned, the problem of so as to avoid greasy dirt from causing picture pick-up device image blur, to ensure that user can obtain
Clearly picture, and lift experience of user when using picture pick-up device.
As shown in figure 3, the picture processing system 10 include acquisition module 100, determining module 101,
And processing module 102.Module alleged by the present invention refer to one kind can be processed equipment 30 it is performed and
The series of computation machine program segment of fixing function can be completed, it is stored in storage device 20.In this reality
Apply in example, the function on each module will be described in detail in follow-up embodiment.
The acquisition module 100, for obtaining pending picture.
In the present embodiment, when user is using the picture pick-up device 40 shooting picture, the acquisition module
100 obtain the picture captured by the picture pick-up device 40, using acquired picture as pending picture.
In other embodiments, the acquisition module 100 can also receive the picture of other users transmission, and
Using the picture received as pending picture, or directly read from the storage device 20 pending
Picture.
The determining module 101, for the pending picture segmentation into more sub-regions, to be calculated every
The contrast of sub-regions, and the fuzzy of the pending picture is determined according to the contrast of every sub-regions
Degree.
In the present embodiment, the determining module 101 by the pending picture segmentation into more sub-regions,
The contrast per sub-regions is calculated, the pending picture is determined according to the contrast of every sub-regions
Fog-level.In the present embodiment, the fog-level of the pending picture can include, but are not limited to：
Slightly, moderate, severe.
Further, when the contrast in the pending picture per sub-regions is default all not less than first
During value, the determining module 101 determines that the fog-level of the pending picture is slight, the determination
Module 101 determines that the pending picture is clear picture or slight blurred picture.
When the contrast for having at least one subregion in the pending picture is less than the first preset value and is more than
During the second preset value, the determining module 101 determines that the fog-level of the pending picture is moderate.
When the contrast for the subregion for having predetermined number in the pending picture is not more than the second preset value
When, the determining module 101 determines that the fog-level of the pending picture is severe.The present count
Measure as preset value, self-defined setting can be carried out according to the actual requirements.
First preset value is more than second preset value, and first preset value, described second are preset
Value, the value of predetermined number carry out self-defined setting according to the actual requirements.
