Your photo is out of focus.  We cannot say for sure what you may be dealing with.  However, it is possible that the brown areas may be due to late season issues such as uneven ripening.
Cool temperatures in late summer and early fall combined with diminishing daylight may prevent fruits from ripening fully. This is often observed in tomato and pepper crops. Cool weather will also cause blotchiness and odd colored patterns on fruits. See more on our website http://extension.umd.edu/growit/uneven-ripening-vegetables                                   mh
