Abstract
An object of the invention is to designate an image compressing system every tile. To achieve this object, an image input device is constructed by an image scanner, a film scanner, an electronic camera, etc. Image data inputted by the image input device are stored to an image memory. A discriminating circuit reads the image data from the image memory and discriminates area information of the read image every tile. A converting circuit converts the image stored to the image memory to a flashpix image on the basis of the area information discriminated by the discriminating circuit.
Claims24
An image processor comprising:
- an input device adapted to input an input image;
- a controller adapted to cause a memory to store the input image;
- a discriminator adapted to discriminate area information of the image stored in the memory by determining, for an area of the image, a type of image included within the area, and by determining a larger area including that area and having the same image type;
- and
- a converter adapted to convert the input image to a particular format on the basis of discriminating results obtained by said discriminator,
- wherein said discriminator determines a type for compression of the area by determining the larger area when a plurality of image types exist within the area, and to determine the larger area, without changing the image data, a size of the area is discriminated directly.
An image processing method comprising the steps of:
- a control step, of causing a memory to store an input image;
- a discriminating step, of discriminating area information of the image stored in the memory, by determining, for an area of the image, a type of image included in the area, and by determining a larger area including that area and having the same image type;
- and
- a converting step, of converting the input image to a particular format on the basis of discriminating results obtained in the discriminating step,
- wherein the discriminating step includes determining a type for compression of the area by determining the larger area when a plurality of image types exist within the area, and to determine the larger area, without changing the image data, a size of the area is discriminated directly.
A computer-readable memory medium storing a program for executing the steps comprising:
- a control step, of causing a memory to store an input image;
- a discriminating step, of discriminating area information of the image stored in the memory;
- and
- a converting step, of converting the input image to a particular format on the basis of discriminating results obtained in the discriminating step,
- wherein the discriminating step includes determining a type for compression of the area by determining the larger area when a plurality of image types exist within the area, and to determine the larger area, without changing the image data, a size of the area is discriminated directly.
