As shown in Figure 9, the present invention further illustrates and how to see through one of N image source of aforementioned image acquisition method acquisitionPart or total data, and be applied to an image capture unit. One embodiment of the method comprises the following step.
Step S910: read the acquisition of K group and set, every group of acquisition set a corresponding code and put in order, and often this code is arrangedOrder is made up of multiple code, and the plurality of code represents respectively this N image source, and often this code packages contains M A carry digitUnit, wherein the M power of A is not less than N, and this N, K, M and A are positive integer. For example, refer to Fig. 8 and table 1, according to Fig. 8'sThe pixel format arrangement mode of image output 820, step 910 can read accordingly two groups of acquisitions as shown in table 1 and setSet1 and Set2, the wherein corresponding code of the Set1 0_1_0_1_0_1 that puts in order, and corresponding another code of Set2 1_0_ that puts in order1_0_1_0, each code puts in order and is made up of code 0 and code 1, and code 0 and code 1 represent respectively image source 812With image source 814, and each code packages is containing a binary bit bit.
Step S920: the code that reads every group of acquisition setting puts in order, and sequentially capture every that this code puts in orderThe data in the image source of this code representative. For instance, refer to Fig. 8 and table 1, when wanting pick-up image source 812,814Data when forming a V horizontal scanning line (wherein V is as positive integer), the code that step S920 can read Set1 puts in order0_1_0_1_0_1, and inferior pixel in pick-up image source 812,814 in turn sequentially, capturing after 6 inferior pixels stepS920 puts in order and again captures according to this code, altogether capturing number of times is W time, and wherein W is relevant to image output 820The width width of this V horizontal scanning line (or say), this image output 820 is the image data institute structures that captured by this stepBecome, be used for exporting to directly or after treatment the display of rear end, and in this example, the number of codes that this code puts in orderThe product that (that is 6) corresponding number of pixels (that is 2) is multiplied by total acquisition number of times W can be equal to or less than this image output 820Width, for example, in the time that the width of this image output 820 is 800 pixels, the product that above-mentioned number of pixels 2 is multiplied by W equals800, now W is 400, that is step S920 altogether puts in order and carried out the acquisition of 400 times according to this code, captures 2 at every turnIndividual pixel (or 6 pixels), so that the data that captured are formed to this V horizontal scanning line, if but number of pixels is multiplied by taking advantage of of WThe long-pending width that cannot just equal image output 820, this product can be less than the width of this image output 820, or rather,This product adds that a remainder number just can equal the width of this image output 820, and now step S920 is in the acquisition that completes W timeAfter, can put in order and capture the pixel (or inferior pixel of three times of these remainder numbers) that equals this remainder number, mat according to this code againThis completes the data acquisition of this V horizontal scanning line; And putting in order after data acquisition according to the code of Set1, stepS920 puts in order and carries out follow-up data acquisition according to the code of Set2 in the same manner again, to form (V+1) horizontal sweepLine, just can set according to all acquisitions the data of the continuous horizontal scan line with different pixels arrangement mode by that analogyAcquisition. Furthermore,, for completing the data acquisition of horizontal scanning line as above, step S920 can comprise the following stepS922 and S924.
Step S922: in read the Group X acquisition of this K group acquisition in setting set (for example acquisition set Set1 orSet2, this X is the positive integer that is not more than K) code while putting in order, the number of the multiple codes that put in order according to this codeCount, to produce a count results.
Step S924: capture often this code institute that code that the acquisition of this Group X sets puts in order according to this count resultsThe data in the image source of representative reach W time, and the related definition of this W and explanation are as aforementioned. In more detail, if this image output820 width is 800 pixels, and the number of codes that this code puts in order is 6 pixels (equaling 2 pixels), stepS924 can be in the time that this count results be 6 or 6 multiple, again captures often should that code that the acquisition of this Group X sets puts in orderThe data in the image source of code representative, and the number of times that is 6 in this count results adds up to 2 pictures of 400(800 pixel ÷Element) when inferior or when this count results equals 6 × 400=2400, stop the action that this captures again, now step S924 completesThe data acquisition of one horizontal scanning line.
The width that note that above-mentioned image output 820 can be the width of viewable pictures or the width of complete picture, this skillArt field has knows that the knowledgeable can suitably apply the present invention according to announcement of the present invention and enforcement demand conventionally.
From the above, because the horizontal scanning line number of image output has a different pixels arrangement mode more than aforementioned conventionallyThe number (that is this acquisition set number K) of continuous horizontal scan line, therefore, in order to obtain all water of this image outputThe data of scan lines, it is not shown that the present embodiment can further comprise the following step S930 ~ S940().
Step S930: temporary this K group acquisition is set, by this without repeated execution of steps S910. Step S940: make stepThe execution number of times of S920 reaches H time, and wherein this H is relevant to the height of an image output, or rather, and the number K that acquisition is setThe product that is multiplied by total execution number of times H of step S920 can be equal to or less than the height of this image output. For example, refer to figure8 with the example shown in table 1, in this example, acquisition is set the number K of (Set1, Set2) and is equaled 2, supposes this image output 820Be highly 600 scan lines, the product that the number 2 that acquisition is set is multiplied by execution number of times H should equal 600, therefore H is 300, alsoBe that step S940 makes the execution number of times of step S920 reach altogether 300 times, all have the data of two horizontal scanning lines to be captured at every turn,Complete by this data acquisition of all horizontal scanning lines of this image output 820, but, if being multiplied by, holds the number K that acquisition is setThe product that places is counted H cannot just equal the height of this image output 820, and this product can be less than the height of this image output 820Degree, or rather, this product adds that a remainder number just can equal the height of this image output 820, now step S940 existsThe execution number of times of step S920 is reached after H time, and the order that can set according to this one or more acquisition again performs step S920 and reachesThe number of times of this remainder number, completes the data acquisition of all horizontal scanning lines of this image output 820 by this. Note that this is defeatedThe height that goes out image 820 can be the height of viewable pictures or the height of complete picture.
Separately note that under the prerequisite of setting in not temporary this K group acquisition, above-mentioned steps S930 and S940 can be by the following stepsReplace (not shown): step S950: the execution number of times of step S910 and S920 is reached H time respectively, wherein the related definition of this HAnd explanation is as aforementioned.
