Abstract
A focus estimating device has an area setting unit which sets an area in which focusing of an image is determined and divides the area into a plurality of blocks, a block selecting unit which selects a block to be used for focus determination, a block focus determination unit which performs focus determination for each block from an edge in each color component of the block selected by the block selecting unit, and a focus determination unit which determines focusing of the area based on the focus determination.
Claims32
A focus estimating device comprising:
- an area setting unit setting an area in which focusing of an image is determined and dividing the area into a plurality of blocks;
- a block selecting unit selecting a block to be used for focus determination:
- a block focus determination unit performing focus determination for each block from an edge in each color component of the block selected by the block selecting unit;
- and
- a focus determination unit determining focusing of the area based on the focus determination.
A focus estimating device comprising:
- an area setting unit setting an area in which focusing of an image is determined and dividing the area into a plurality of blocks;
- a block selecting unit selecting the block including an edge;
- a block focus determination unit performing focus determination for each block from an edge in each color component of the block selected by the block selecting unit;
- and
- a focus determination unit determining focusing of the area based on the focus determination.
