Title: Focus detector
Inventor: KUWATA TOMOYUKI
IPC: G02B7/34
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To maintain the measuring accuracy of a focus detector at a high level by correcting and outputting a focusing state calculated by a focus detection part based on correction data generated by a test part. SOLUTION: A microprocessor 30 reads out a photoelectric conversion signal from a photoelectric conversion element train 28, performs pattern-matching concerning the photoelectric conversion signal and calculates a phase difference concerning a pair of divided images formed on the train 28. The microprocessor 30 calculates coarse defocus amount based on the phase difference. Next, it offset-corrects the coarse defocus amount by an amount equivalent to the correction data stored when a test mode is set, calculates the accurate defocus amount and outputs the corrected defocus amount so as to submit it for focus control on a camera side. In such a case, stable optical characteristic is obtained over a long term by making a correction lens 25 to be made of glass.
