In addition, from (the x that represents to obtain by EF processing unit 107 and WB processing unit 109, y) numerical value of the forecasting accuracy of Zhi indoor or outdoors, and (x, y) near the state of indoor or outdoors the value, comprehensively judge whether change the judgement that is used for indoor or outdoors shown in Figure 3 threshold value (x, y), change if be judged as, then update stored in the database in the memory storage 113.
Below with the operational processes of the photographic equipment among process description second embodiment of Fig. 9 A, 9B.
In step S601, obtain the brightness value X of subject with AE processing unit 104.And, in the processing of the iSAPS unit 105 of step S603, the highest object distance Y0 of frequency in the brightness value corresponding with this brightness value X that tries to achieve is retrieved in iSAPS unit 105 from database 113, and then obtain object distance Y0 around, frequency values surpass certain threshold value the object distance scope (Y1, Y2).
In step S602, the highest object distance Y0 and object distance scope (Y1, value Y2) of frequency that 106 acceptance of AF processing unit are tried to achieve from iSAPS unit 105.And, will (Y1, Y2) the driving scope of Dui Ying amasthenic lens be set at sweep limit, carries out focusing operation with the object distance scope.In the example of Fig. 3, step S1～S4 is the object distance scope corresponding with sweep limit.
In step S604,, then enter step S610 if focusing operation is finished.In addition, do not aim at the focal position, then enter step S605 if in above-mentioned sweep limit, reach.
In step S605, confirm the variation of focus level of the amasthenic lens of each position, based on the degree of this variation, judgement should aim at the position of focus than (Y1, Y2) near unlimited distally still near nearside.The position is in the infinity side if be judged as in focus, then enters step S606, will the object distance scope corresponding with sweep limit be decided to be that (Y2 ∞), begins focusing operation once more.And, in step S608,, then enter step S610 if focusing operation is finished, if also do not reach in focus, then enter step S612.
On the other hand, in step S607, the position is in nearest side if be judged as in focus, then will the object distance scope corresponding with sweep limit be decided to be (0, Y1), carry out focusing operation once more.And, in step S609,, then enter step S610 if focusing operation is finished, if do not reach in focus, then enter step S612.
In step S610, obtain the object distance Y corresponding with the position in focus of amasthenic lens.And, in step S611,, then object distance Y that obtains and the brightness value X that obtains in step S601 are outputed in the iSAPS unit 105, more the data of new database 113 if learning functionality SW14 is an opening.
In addition, in the processing of the aligning focal position that in step S612, does not reach, make that the position is corresponding with the object distance Y=Y0 that obtains in focus in step S602, drive amasthenic lens.
Then, in step S613, judge that from brightness value X and the range information Y that tries to achieve subject is in indoor or outdoor.As judging material, use the threshold value that stores into from iSAPS unit 105 database 113 (x, y).
In step S614, if subject brightness value X is equal to or less than x and object distance Y is equal to or less than y, then be judged as indoor photography, enter step S615.On the other hand, if not so, just enter step S616.
In step S615, S616, judge whether flashlamp is luminous, if luminous, the indoor luminous and actual luminous quantity that then enters step S617 respectively determines that the pre-luminous and actual luminous quantity of outdoor use of processing or step S618 is definite.In addition, luminous if flashlamp does not have, the indoor AWB that then enters step S625 respectively handles or the AWB of the outdoor use of step S626 handles.
In step S617, S616, at first according to outdoor and indoor difference, the test luminous quantity of the luminous quantity when being identified for setting actual exposure.The test luminous quantity be set at indoor less, outdoor many.Use with this test is luminous and carry out brightness value that photometry obtains simultaneously and the computing of the external light intensity value that the photometry before luminous obtains with test, determine actual luminous quantity.
After determining actual luminous quantity, in step S619, S620, whether the prediction of the indoor or outdoors that determining step S614 carries out is genuine correct.This judgement is the luminous quantity of predicting with the object distance that for example obtains based on the external light intensity value that obtains with the photometry of test before luminous with range finding, and with the brightness value of following the luminous photometry of carrying out of test to obtain with judge with the error of testing the actual luminous quantity that external light intensity value that luminous preceding photometry obtains tries to achieve.
As judged result,, then enter the indoor AWB processing of step S625 or the outdoor AWB of step S626 and handle if judge that indoor or outdoors is judged as correctly.On the other hand, as judged result, if being out of one's reckoning of indoor or outdoors then enters step S621 or step S622 respectively.At this, the numerical value that adopts the incorrect degree of result of representing the judgement indoor or outdoors is as the margin of error.For example be as described above, test the luminous quantity of luminous time prediction and the error of actual luminous quantity.
