Abstract
An image scanning apparatus includes a scanning unit configured to scan an original document and generate a scanned image, a storage unit configured to store the generated scanned image, an image processor including a plurality of image processing modules, the plurality of image processing modules separately including a plurality of buffers configured to store the scanned image of block units, and configured to read the generated scanned image in preset block units and perform image processing on the scanned image read in block units sequentially using the plurality of image processing modules, and a controller configured to store the image-processed scanned image in the storage unit.
Claims22
An image scanning apparatus, comprising:
- a scanning unit configured to scan an original document and generate a scanned image;
- a storage unit configured to store the generated scanned image;
- an image processor including a plurality of image processing modules, the plurality of image processing modules separately including a plurality of buffers configured to store the scanned image of block units, and configured to read the generated scanned image in preset block units and perform image processing on the scanned image read in block units sequentially using the plurality of image processing modules;
- and
- a controller configured to store the image-processed scanned image in the storage unit.
An image compensation method of an image scanning apparatus, the method comprising:
- scanning an original document to generate a scanned image;
- storing the generated scanned image;
- reading the generated scanned image in preset block units;
- performing image processing on the scanned image read in block units sequentially using a plurality of image processing modules separately including a plurality of buffers configured to store the scanned image of block units;
- and
- storing the image-processed scanned image.
An image scanning apparatus, comprising:
- a scanning unit configured to scan an original document and generate a scanned image;
- a storage unit configured to store the generated scanned image;
- and
- an image processor including a plurality of image processing modules connected to a plurality of buffers to store data processed in the corresponding image processing modules, and configured to read the generated scanned image in the block units and sequentially perform image processing on the scanned image read in block units using the plurality of image processing modules, the image processing including a skew compensation and at least one of Gamma correction and color correction, and segmentation.
