A frame memory of an image recording apparatus includes a first frame memory for storing image data having a large number of pixels per unit area and a small number of gradations per pixel and a second frame memory for storing image data having a small number of pixels per unit area and a large number of gradations per pixel. Image data representing a character, a graphic figure or similar items requiring a high resolution is stored in the first frame memory, while image data inputted through a scanner or similar device and having a large number of gradations is stored in the second frame memory. In recording an image, the image data stored in the first frame memory is converted to image data having a large number of gradations, and the image data stored in the second frame memory is converted to image data having a high resolution, and recording is effected on the basis of these image data. As a result, images are recorded with high image quality by using a small-capacity frame memory. |

DETAILED DESCRIPTION Accordingly, it is a primary object of the present invention to provide an image recording method capable of reducing the capacity of a frame memory and of recording images with high image quality.
A second object of the present invention is to provide an image recording apparatus capable of reducing the capacity of a frame memory and of recording images with high image quality.
To attain the first object, in accordance with a first aspect of the invention, there is provided an image recording method comprising the steps of: if an image represented by image data can be expressed as an image having a small number of gradations per pixel, storing the image data in first storage means for storing image data having a large number of pixels per unit area and a small number of gradations per pixel, and if the image represented by the image data cannot be expressed as an image having a small number of gradations per pixel, storing the image data in second storage means for storing image data having a small number of pixels per unit area and a large number of gradations per pixel; converting the image data stored in the first storage means to image data having a large number of gradations per pixel, and converting the image data stored in the second storage means to image data having a large number of pixels per unit area; and recording an image on the basis of the converted image data.
In accordance with a second aspect of the invention, there is provided an image recording method comprising the steps of: if an image represented by image data can be expressed as an image having a small number of pixels per unit area, storing the image data in second storage means for storing image data having a small number of pixels per unit area and a large number of gradations per pixel, and if the image represented by the image data cannot be expressed as an image having a small number of pixels per unit area, storing the image data in first storage means for storing image data having a large number of pixels per unit area and a small number of gradations per pixel; converting the image data stored in the first storage means to image data having a large number of gradations per pixel, and converting the image data stored in the second storage means to image data having a large number of pixels per unit area; and recording an image on the basis of the converted image data
