Abstract:
An image forming apparatus comprising:a detector for detecting a size of a single unit of image data, wherein said unit of image data has a vertical component and a horizontal component that is representative of a frame size of an image to be formed from said unit of image data;a first image processor for emphasizing a contrast of said unit of image data so as to adjust an image to be formed from said unit of image data;a second image processor for emphasizing an edge of the unit of image data so as to adjust an image to be formed from said unit of image data; anda determination unit having a memory means, for storing at least one predetermined image frame size, and a comparator for comparing at least one of the vertical component and the horizontal component of said unit of image data with a thus stored predetermined image frame size;wherein the determination unit causes said first image processor to utilize a process of contrast emphasis in order to adjust the image to be formed from said unit of image data when at least one of the vertical component and the horizontal component of said unit of image data is smaller than a comparable aspect(s) of the thus compared predetermined image frame size; andwherein the determination unit causes said second image processor to utilize a process of edge emphasis in order to adjust the image to be formed from said unit of image data when at least one of the vertical component and the horizontal component of said unit of image data is larger than a comparable aspect(s) of the thus compared predetermined image frame size.
