At first, in step S101, be used for confirming the processing (AE processing) and the automatic focus (AF processing) of exposure.In exposure confirm to be handled, for example similar with the said aperture mode of priority, the aperture time when obtaining aforementioned suitable exposure with respect to preset aperture value.Particularly; The average luminance of the photometry region of supposing to be measured by photometry sensor 108 shown in Figure 4 402 is identical with the average luminance that the quilt with reflectivity of 18% is taken the photograph body, and aperture time is determined to be and makes the output valve of image sensor 110 equate with preset value.During the automatic focus in step S101, carried out is handled, as during explanation transducer 103, having mentioned, drive focus lens group 201 and make that any of automatic focus indicateing arm 403 to 406 will be by in focus.
Then, in step S102, according to the aperture time that the color chart type correction that is taken is confirmed in step S101.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.According to the color chart type that is taken is stored these corrections in advance in camera control unit 111.The method of confirming the color table graph type can be: for example, when taking, selected or the sea dye graph type by the user.Through suitably adjusting exposure according to above-mentioned color chart type as stated, 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 generating in the color chart image.
In step S103; By lens control unit 206 obtain by encoder 205 confirm to taken the photograph body apart from d, based on the definite focal distance f of the positional information of variable focus lens package 202 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), the diameter of the circle of confusion (circle of confusion) that σ representes to allow, its size with a pixel of image sensor 110 is corresponding.
In step S104, calculate and taken the photograph body size h.When used herein, taken the photograph the size that body size h is meant the color chart that will be taken.In the determining step S106 that carries out after a while, will mention this quilt and take the photograph body size h.When by the color chart size of being taken the photograph body size h and being scheduled to not simultaneously, judging and being taken the photograph body is not color chart.
For example, can calculate through following formula and taken the photograph body 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
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 by transducer 103 and the corresponding output valve in position indicateing arm 403 to 406 in the position of indicateing arm 403 to 406 to the distance of being taken the photograph body.Then, calculate maximum and minimum value poor of the distance of being taken the photograph body, and this difference is appointed as Δ L.
Step S106 takes determining step.This step through based on above-mentioned ultimate range difference Δ L, depth of field o, by take the photograph body size h, to taken the photograph body whether taken the photograph body apart from the d judgement be whether the position of color chart or color chart suitably judges whether to take.
Particularly, if taken the photograph body size h greater than predetermined threshold Tm1 and less than predetermined threshold Tm2, the size of then marking on a map because of the size of being taken the photograph body and predetermined color is different, and therefore, judging and being taken the photograph body is not color chart, and sign (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 because supposition departs from the position that color chart is taken frame 401 as the color chart of being taken the photograph body, therefore, indicates to be 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 confirming among step S101 and the 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 in the color chart screening-mode, can suitably take color chart the time.Likewise, 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 departing from color chart shooting frame 401 as the color chart of being taken the photograph body, because the sensor output value in the prediction automatic focus indicateing arm 403 to 406 is high, therefore, ultimate range difference Δ L becomes greater than predetermined threshold TL.Therefore, it is inappropriate to judge the color chart shooting, show " NG ", and result.
According to this execution mode, judge before that in the color chart shooting of wanting to produce the chromatic characteristic description document can suitably carry out color chart takes, and show judged result, can not take color chart if judge, then forbid shooting.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 through the time, can also suitably set focus according to the definite aperture value of this distance.
In addition, through 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 and improve to utilize precision about the chromatic characteristic description document of the information generating of the color chart image taken.
