PROBLEM TO BE SOLVED: To obtain high-accuracy survey drawings by performing the optimum distortion correction. SOLUTION: A camera 100 is provided with a CCD 21 which takes the picture of an object. A survey drawing obtained by means of the CCD 21 is outputted to a record control circuit 72 as picture data composed of digital signals. A system control circuit 50 reads out the distortion correction value corresponding to the stop value at the time of taking the picture and outputs the value to the control circuit 72. The circuit 72 stores the correction value on a memory card 30 together with the picture data. A picture processor draws the survey drawing by reading out the picture data and distortion correction value from the memory card 30. |
