Below use Fig. 2 that distance measuring equipment 101a and view finder 101b are described.
Above-mentioned distance measuring equipment 101a incides the image of subject 1 on linear sensor 3a, the 3b respectively by a pair of sensitive lens 2a, 2b.The subject view data of this linear sensor 3a, 3b output is carried out the predetermined processing of integration and mould/number conversion etc., and be input to arithmetic control circuit 4.In this arithmetic control circuit 4,, obtain ranging data according to well-known range of triangle principle, and object distance is carried out computing according to this ranging data according to the phase differential of subject view data of a pair of above-mentioned linear sensor 3a, 3b output.According to the object distance of obtaining, drive the photography of can focusing automatically of this camera by the focusing of carrying out photographic lens.
And the view finder 101b of this camera is made up of view finder visual field frame 5 that is provided with target label quarter and eyepiece 6 etc.
In the computing of above-mentioned object distance,, be necessary each camera is adjusted for to because the error that the deviation of the size of the component parts of distance measuring equipment and assembling causes is proofreaied and correct.
When the phase differential that utilizes the subject view data that is detected by a pair of linear sensor carries out range of triangle, there is proportionate relationship shown in Figure 3 between the inverse of ranging data and object distance (1/ distance).The adjusting gear of Fig. 1 passes through closely configuration distance L 1, L2 and ranging data AFD1, the AFD2 of side card 102, remote side card 103, obtain the gradient and the intercept of the straight line of Fig. 3 at each camera, be used for when reality is photographed, obtaining the computing of object distance from the ranging data computing.
The gradient of above-mentioned straight line and intercept are used as the range finding adjusted value and are stored in the interior not volatile memory of camera.
In addition, in the present embodiment,, use above-mentioned remote side card 103, so that simultaneously the view finder visual field of camera and the deviation in the range finding visual field are adjusted by threadlike graph 114 (with reference to Fig. 5 (a)) is projected on the remote card 103.That is to say, be used for the card that the deviation between the visual field is adjusted to the view finder visual field and range finding, and the card (be meant and be used to obtain the remote with card 103 of above-mentioned range finding adjusted value) that is used for the deviation beyond this deviation adjustment is adjusted is shared here.
And the AFD1 among Fig. 3 shows the ranging data when closely side card 102 is found range, and AFD2 shows the ranging data when remote side card 103 found range.
Below the visual field deviation between the visual field is adjusted to the view finder visual field and range finding method describe.
That catch and to be presented at the vertical direction mark 116a (with reference to Fig. 6) of the target label in the view finder visual field on the monitor 110 consistent with figure 113 with the target alignment of the remote side card 103 shown in Fig. 5 (a) for the CCD camera 109 that uses Fig. 1, use to drive platform 100 and make camera 101 and 109 the two motions in the horizontal together of CCD camera.Afterwards, by perverse some instrument 104 of laser threadlike graph 114 is projected on the adjustment homing position in the range finding visual field.And in Fig. 5 (a), symbol 114 is illustrated in the view finder visual field of camera 101 and range finding when the visual field deviation between the visual field is adjusted, by the threadlike graph of perverse some instrument of laser 104 projections.And, the view finder visual field of the symbol 115 expression cameras 101 among Fig. 6, symbol 116a represents the vertical direction mark in the target label.
The reason that the adjustment homing position in the above-mentioned range finding visual field departs from figure 113 from target alignment is owing to the parallax of having considered between distance measuring equipment 101a and the view finder 101b.
