Abstract
An image processing circuit reduces binary data of an original image. At least one line buffer stores data of each line of the original image. At least one line buffer stores data of each line of a reduced image. An operation part performs a logical operation based on data of focused pixels of the original image, data of a peripheral pixel of the focused pixels, and data of peripheral pixels of a pixel of the reduced image, the pixel of the reduced image corresponding to the focused pixels.
Claims15
An image processing circuit reducing binary data of an original image, comprising:
- at least one line buffer storing data of each line of the original image;
- at least one line buffer storing data of each line of a reduced image;
- and
- an operation part performing a logical operation based on data of focused pixels of the original image, data of a peripheral pixel of the focused pixels, and data of peripheral pixels of a pixel of the reduced image, the pixel of the reduced image corresponding to the focused pixels.
An image processing circuit reducing binary data of an original image, comprising:
- first line buffer means for storing data of each line of the original image;
- second line buffer means for storing data of each line of a reduced image;
- and
- an operation means for performing a logical operation based on data of focused pixels of the original image, data of a peripheral pixel of the focused pixels, and data of peripheral pixels of a pixel of the reduced image, the pixel of the reduced image corresponding to the focused pixels.
An image processing method of reducing binary data of an original image, comprising the steps of:
- storing data of each line of the original image;
- storing data of each line of a reduced image;
- and
- performing a logical operation based on data of focused pixels of the original image, data of a peripheral pixel of the focused pixels, and data of peripheral pixels of a pixel of the reduced image, the pixel of the reduced image corresponding to the focused pixels.
