＜color chart photographing process 〉
Fig. 5 is the flow chart of the photographing process of being undertaken by camera control unit 111 in the color chart screening-mode.Be set at mode initialization dish 301 under the state of color chart screening-mode position 301f, when the user partly pressed shutter release 113, this algorithm began.
At first, in step S101, be used for determining the processing (AE processing) and the automatic focus (AF processing) of exposure.In exposure determine to be handled, for example similar with the said aperture mode of priority, the aperture time when obtaining aforementioned suitable exposure with respect to default aperture value.Particularly, the average luminance of supposing the photometry region shown in Figure 4 402 that measured by photometry sensor 108 is identical with the average luminance of the subject with reflectivity of 18%, and aperture time is determined to be and makes the output valve of image sensor 110 equate with preset value.During the automatic focus carried out in step S101 was handled, as having mentioned during explanation transducer 103 like that, driving focus lens group 201 made that any of automatic focus indicateing arm 403 to 406 will be by in focus.
Then, in step S102, the aperture time of in step S101, determining according to the color chart type correction that will be taken.Particularly, under the situation of the average reflectance that is positioned near the colour code the photometry region 402, make the brighter variation of color chart (to prolong aperture time) greater than 18% color chart.On the contrary, under the situation of the average reflectance that is positioned near the colour code the photometry region 402, make the darker variation of color chart (to shorten aperture time) less than 18% color chart.In camera control unit 111, store these corrections in advance according to the color chart type that will be taken.The method of determining the color table graph type can be: for example, when taking, selected or the sea dye graph type by the user.By suitably adjusting exposure according to above-mentioned color chart type as mentioned above, can obtain more suitable color chart image.That is to say, can improve the precision of the chromatic characteristic description document of utilizing a plurality of colour code information generations in the color chart image.
In step S103, by lens control unit 206 obtain by encoder 205 determine to the focal distance f of determining apart from d, based on the positional information of variable focus lens package 202 of subject and based on the definite F number in the aperture of aperture 204, and calculate the depth of field (depth of field) o based on above-mentioned information.For example, can utilize following formula (1) to formula (3) to calculate depth of field o, still, this calculating is not limited thereto.
o＝2σFm
2·····(1)
t＝d/f·····(3)
In formula (1), σ represents the diameter of the circle of confusion (circle of confusion) of allowing, its size with a pixel of image sensor 110 is corresponding.
In step S104, calculate subject size h.When used herein, subject size h is meant the size of the color chart that will be taken.In the determining step S106 that carries out after a while, will mention this subject size h.When subject size h and predetermined color chart size not simultaneously, judging subject is not color chart.
For example, can calculate subject size h, wherein, take the length quilt of the corresponding image sensor 110 of the length on one side of frame 401 with color chart shown in Figure 4 by following formula
h＝|k/m|·····(4)
In step S105, calculate the ultimate range difference Δ L of automatic focus indicateing arm shown in Figure 4 403 to 406 (being designated hereinafter simply as " indicateing arm ").In this step, at first, estimate the distance in the position of indicateing arm 403 to 406 by the corresponding output valve in the position with indicateing arm 403 to 406 of transducer 103 to subject.Then, calculate the poor of the maximum of distance of subject and minimum value, and this difference is appointed as Δ L.
Step S106 takes determining step.This step is by based on above-mentioned ultimate range difference Δ L, depth of field o, subject size h, judge apart from d whether subject is whether the position of color chart or color chart suitably judges whether to take to subject.
Particularly, if subject size h greater than predetermined threshold Tm1 and less than predetermined threshold Tm2, then because the size that the size of subject and predetermined color are marked on a map is different, therefore, judging subject is not color chart, indicates that (flag) is set to FALSE (vacation).If ultimate range difference Δ L is greater than depth of field o, then because can not obtain whole color chart all by in focus image, therefore, sign is set to FALSE.In addition, if ultimate range difference Δ L greater than predetermined threshold TL, then departs from the position that color chart is taken frame 401 because suppose the color chart as subject, therefore, sign is set to FALSE.
If sign is set to FALSE, then handle and advance to step S108, wherein, showing the message " NG " that provides expression can not take color chart to the user on the display unit 407 as a result, and processing finishes.On the other hand, if in determining step S106, sign is set to TRUE (very), then showing the message " OK " that provides expression can take color chart to the user on the display unit 407 as a result, and processing advances to step S110 to carry out photograph processing.
When in step S109, judging shutter release 113, carry out photograph processing step S110 by total head following time.In photograph processing step S110, as previously mentioned, image sensor 110 is based on the exposure exposure of determining in step S101 and S102, and the view data that record obtains in the recording medium in read/write cell 112.
Fig. 6 A is the figure that illustrates when judging the embodiment that view finder shows can suitably take color chart in the color chart screening-mode time.Similarly, Fig. 6 B is the figure that illustrates when judging the embodiment that view finder shows can not suitably take color chart the time.Shown in Fig. 6 B, when the color chart as subject departed from color chart shooting frame 401, because the sensor output value height in the prediction automatic focus indicateing arm 403 to 406, therefore, ultimate range difference Δ L became greater than predetermined threshold TL.Therefore, it is inappropriate to judge the color chart shooting, show " NG ", and result.
According to present embodiment, judged that before the color chart of wanting to produce the chromatic characteristic description document is taken can suitably carry out color chart takes, and show judged result, can not take color chart if judge, then forbid taking.Particularly, utilize the judgement of carrying out based on the distance of a plurality of indicateing arms in coverage to prevent the position deviation of color chart.When by the time, can also suitably set focus according to the definite aperture value of this distance.
In addition, by correction is used for the exposure of light value according to the color chart type, can carries out color chart with suitable exposure and take.Thus, can always carry out the color chart shooting,, also can easily carry out suitable shooting even for the user who does not take the color chart experience with correct color chart position, correct focus and correct visual angle.As a result, can expect precision that improve to utilize the chromatic characteristic description document that the information about the color chart image taken produces.
