Abstract
An image processing device includes a bit length determiner configured to determine a bit length which indicates a number of at least one bit from among all bits of image data, an upper bit extractor configured to extract, from the image data, at least one upper bit corresponding to the bit length, and a noise processing unit configured to perform noise reduction processing for a target pixel using the at least one upper bit of the image data.

An image processing device comprising:
- a bit length determiner configured to determine a bit length which indicates a number of at least one bit from among all bits of image data;
- an upper bit extractor configured to extract, from the image data, at least one upper bit corresponding to the bit length;
- and
- a noise processing unit configured to perform noise reduction processing for a target pixel using the at least one upper bit of the image data.
1 more element
An image processing device comprising:
- a bit length determiner configured to determine a bit length, which indicates a number of at least one bit from among all bits of image data, based on characteristic information of an image sensing device which generated the image data or characteristic information of the image data;
- and
- a noise processing unit configured to perform noise reduction processing for a target pixel using at least one upper bit corresponding to the bit length, the at least one upper bit being extracted from the image data.
