When video receiver 220 sees through networking 230 and connects with image capture unit 210, the user can on video receiver 220, watch by image capture unit 210 acquisitions to raw video.And in the time of video receiver 220 beginning pick-up images, change block judgment means 211 promptly obtained image to be divided into a plurality of units block, and calculate and write down the average RGB value of each unit block respectively.
With the mega pixel video camera is example, its resolution is 1280*1024dpi (Dot per inch), if the size of the unit block of cutting is 32*32dpi, then always to meet together and form 40*32=1280 unit block, the average RGB value of these unit blocks then can be calculated by following formula:
R
b(x，y)＝Avg(R
p(32*x+i，32*y+j)，i＝0...31，j＝0...31)
G
b(x，y)＝Avg(G
p(32*x+i，32*y+j)，i＝0...31，j＝0...31)
B
b(x，y)＝Avg(B
p(32*x+i，32*y+j)，i＝0...31，j＝0...31)
Then, change block judgment means 211 and promptly can when the one section Preset Time in every interval (for example 0.2 second), obtain an image, according to the average RGB value that calculates each unit block with quadrat method, and the average RGB value of corresponding unit block in the average RGB value of each unit block in the back pick-up image and last the pick-up image subtracted each other, and obtain a R difference, a G difference and a B difference respectively.
Change 211 of block judgment means this moment can be with this R difference, G difference and B difference, compare with default R permission, G permission and B permission respectively, when if wherein any R difference, G difference and B difference are greater than this R permission, G permission and B permission, then this unit block of decidable changes, and is a variation unit block and demarcate this unit block.
By that analogy, whether change image and original image that block judgment means 211 can judge behind the one section Preset Time in every interval variant, if judge variant, and in pick-up image, there be n unit block (n is the positive integer more than or equal to 1) to be denoted as when changing the unit block, 212 of area image output devices can determine a target image zone to contain all variation unit's blocks, and see through networking 230 and the image in this target image zone is transferred to video receiver 220 with a default resolution show, so-called default resolution is meant: the resolution of the display screens of video receiver 220, or 230 the transmission frequency ranges that can support in networking.
Fig. 3 is the method flow diagram according to the automatic adjustment of image variation monitoring image that illustrates according to preferred embodiment of the present invention.Please refer to Fig. 3, present embodiment is to utilize the image capture unit pick-up image, and is sent to video receiver with a default resolution, and can adjust monitoring image automatically.Wherein, above-mentioned video receiver can include a display unit and a tape deck, and above-mentioned default resolution can be set for this reason the resolution of display unit or the resolution that can support according to the network bandwidth that is sent to video receiver decides, do not limit its scope, the user can look actual needs, adjusts this default resolution.
At first, image capture unit can be divided into the image that is captured a plurality of units blocks (step S310), and then calculates the image variation of each unit block respectively, and calibrates a plurality of variation units blocks (step S320).Wherein, demarcate the step that changes the unit block and calculate the average RGB value of each unit block in regular turn for elder generation respectively, then when the one section Preset Time in every interval, the difference that compares the average RGB value of each unit block in former and later two pick-up images, and obtain a R difference respectively, a G difference and a B difference, and then with this R difference, G difference and B difference, respectively with a default R permission, a G permission and a B permission are relatively, when arbitrary group of R difference, G difference and B difference are greater than the R permission, when G permission and B permission, then demarcating this unit block is a variation unit block.
All unit blocks all through relatively reach demarcate finish after, then image capture unit can select a target image zone to contain variation unit's block (step S330) of all demarcation.Below enumerate several different execution modes, the method for the mark imagery zone decision that makes eye bright makes everybody can have further for the present invention and understands:
First kind of execution mode, be when selecting this target image zone, more can be, and the capable a plurality of units block that is arranged in delegation in this target image zone that can be included in of this no change with the capable deletion of a no change in the target image zone, but do not comprise variation unit's block of any one demarcation.
Second kind of execution mode, then can be when selecting this target image zone, with the no change row deletion in the target image zone, and these no change row can be included in a plurality of units block that is arranged in row in this target image zone, but do not comprise variation unit's block of any one demarcation.
