Patent ID: 8687083

Claim:
A reference pixel memory storage space configuration method, used to configure a reference pixel memory storage space of a high resolution digital image capturing apparatus, the reference pixel memory storage space comprising a main storage sub-space and an extra storage sub-space, the reference pixel memory storage space configuration method comprising steps of: (a) calculating a first frame to obtain a plurality of first reconstruction reference pixels; (b) storing the plurality of first reconstruction reference pixels in the main storage sub-space; (c) moving a search range window to search the plurality of first reconstruction reference pixels and calculating a second frame by referencing the plurality of first reconstruction reference pixels covered by the search range window to obtain a plurality of second reconstruction reference pixels, wherein when the search range window is moved from a first region to a second region in the main storage sub-space, the first region becomes an available space; and (d) storing the plurality of second reconstruction reference pixels orderly in the extra storage sub-space and the available space of the main storage sub-space.
