Problems solved by technology

[0003] However, in the case of a distance-measuring device capable of measuring distances in a plurality of areas within the shooting screen, if the same method as disclosed in the above-mentioned JP-A No. The error between the theoretical value and the actual distance measurement data caused by the deviation of the optical system or assembly of the device, and if the adjustment is made, the image on the far side of the images set at different distances for adjustment must be enlarged
Therefore, a large space is required in the production plant, and there is a problem that the space utilization rate of the production line deteriorates.
[0004] In addition, if in order to prevent the enlargement of the image, only the adjustment value of the central part of the plurality of distance measurement areas is actually measured, and the adjustment value is used to correct the entire distance measurement area, due to the light received by the distance measurement device Due to the aberration of the lens and the attenuation of the surrounding light, there may be a problem that the distance measurement accuracy in the distance measurement area of ​​​​the surrounding parts will deteriorate.

Abstract

The present invention provided a distance measuring apparatus, adjusting device and adjusting method used for said distance measuring apparatus. In one mode, the adjustment device for a range finder electrically corrects error between logical values and actual measured data, which is caused by variance of a distance measuring optical system of the range finder or assembling. During adjustment, the adjustment device has a plurality adjustment charts installed at different distances to the range finder and obtains an adjustment value for correcting error of tilt and an adjustment value for correcting offset on the basis of distance measurement data obtained by measuring distances to a plurality of adjustment charts with respect to a distance measurement area in the center part and uses an adjustment value for correcting tilt error of the distance measurement area in the center part as an adjustment value for correcting error of tilt and obtains an adjustment value for correcting offset on the basis of distance measurement data obtained by measuring the distance to a shorter-distance chart out of two charts used to obtain the adjustment value for correcting tilt error in the distance measurement area in the center part with respect to a distance measurement area in the peripheral part.

Description

field of invention [0001] The present invention relates to a distance measuring device, an adjustment device and an adjustment method for the distance measuring device, and relates to an adjustment technique of a so-called multi-point distance measuring device capable of measuring distances in multiple areas within a photographing screen of a camera, for example. Background technique [0002] So far, in order to electrically correct the error between the theoretical value and the actual distance measurement data caused by the deviation of the optical system or assembly of the distance measuring device, as disclosed in the Japanese Patent Laid-Open No. 63-198818, it can be based on two It is known to obtain the adjustment value such as the coefficient of the correction error by using the distance data detected at different subject distances. [0003] However, in the case of a distance-measuring device capable of measuring distances in a plurality of areas within the shooting ...
