Description

Ranging type digital camera
[technical field]
The present invention relates to a kind of ranging type digital camera, refer to a kind of ranging type digital camera of tool laser ranging function especially.
[background technology]
The general digital camera that uses all has the function of automatic focusing, so-called automatic focusing is meant from pressing shutter key and opens in a flash to shutter, automatically measure the distance of camera lens and reference object, and regulate the focal position of camera lens in view of the above, the feasible image definition of shooting.But this pattern must obtain the image data in a plurality of focal positions when taking, and prolongs the shutter problem of release time thereby exist.
At present, industry has a kind of interlock ranging type digital camera of release, it mainly is to adopt the optical design auxiliary focusing, concrete operation principle is the refracting telescope that two changeable angles are installed at two stiff ends of digital camera, when rotating the focusing ring (promptly changing the focus point of camera lens) of camera lens, this amount of exercise can pass on the distance measuring equipment by the range finding arm, and drives the refracting telescope be positioned at two stiff ends and rotate.When refracting telescope turns to some angles, the object of focusing will be overlapping by two images (these two images are that the refraction by two refracting telescopes forms) is an image, utilize the range finding structure of this optical ranging system, can be so that when two images overlapped fully, camera lens be finished the focusing to this subject simultaneously.That is to say that camera has been finished the action of focusing in range finding.The detailed open source information of relevant this interlock ranging type digital camera can be consulted the Japan Patent spy and open 2002-303917 number and 2003-295260 number.
Above-mentioned interlock ranging type digital camera is for the digital camera that adopts autofocus system, and its focusing speed ratio is very fast.But, in the use of this interlock ranging type digital camera, also have many shortcomings, for example, because the interlock ranging type digital camera adopts is the parameter that two " observation stations " with certain distance are used as triangulation, and be positioned at the coincidence that refracting telescope that this two " observation station " locate is realized two same image by rotation, but it is to rely on the observation of human eye to realize fully that image overlaps, thereby very easily the sense organ difference because of human eye produces error of focusing, and make that the distance that calculates at this moment can be inaccurate yet, especially when closely focusing, (for example observe when surveying at the moment the object about 30cm because of having intrinsic parallax when choosing, closing left eye earlier sees, close right eye then and see, some difference is understood in the position of twice object before and after it will be appreciated that), thus make image can't overlap at all.In addition,, therefore when changing camera lens,, also need to change the view-finder line that does not have on the camera, use inconvenience thereby cause in order to obtain to find a view more accurately because of this camera needs corresponding view-finder line.In addition owing to do not have camera lens among the employed camera lens group of interlock ranging type digital camera than long-focus, even and change than long focal length lens, also need to change different view-finder lines, shooting therefore is not suitable for looking in the distance.
In addition, building in the measurement, all needing to understand the distance of peripheral scenery and some buildings usually, can also cooperate image simultaneously and not write down accurate range data for filmed image but there is any easy equipment at present.
