The AF sensor module primarily comprises condenser lens 16, mirror 17, aperture mask 18, separator lens 19 and CCD 20. Separator lens 19 is located such that its lengthwise center line M may be parallel to the lengthwise center line N of CCD 20 while it is inclined by micro-angle δ with center line M as the rotational axis. By arranging the lens surface of separator lens 19 and the image pickup surface of CCD 20 such that they are non-parallel to each other, reflected light L1 existing due to the reflection of light between separator lens 19 and CCD 20 is prevented from striking CCD 20 once again so that a reduction in the accuracy of focus detection caused by said reflected light may be prevented.
A detecting device, comprising:
A focus detecting device which detects focus condition of a prescribed optical system, comprising:
A focus detecting device as claimed in claim 6, one of said lens surface and said image pickup surface is inclined with regard to optical axis.
A focus detecting device as claimed in claim 7, wherein said lens surface or said image pickup surface is arranged so that said lens surface or said image pickup surface is inclined pivotally on a line along with a lengthwise direction of said image pickup device.
A camera, comprising:
