1. A processing apparatus comprising:
a first storage unit for storing first array data that is based on output values of a plurality of pixels arranged in an array;
a second storage unit having second array data stored therein to be used for correction of the output values from the plurality of pixels;
a correction unit including a calculation unit configured to correct an output value of at least one pixel of the plurality of pixels based on the first array data and the second array data;
a flaw extraction unit configured to extract an output value and a position of a flaw pixel from the first array data; and
an array generation unit configured to generate third array data based on the second array data and the output value and the position of the flaw pixel,
wherein the second array data is generated based on a pattern of a flaw pixel in an optical black (OB) region of the plurality of pixels.
