Abstract:
An image processing apparatus comprising:compression means for compressing pixel data of a character image block at one of a plurality of predetermined compression ratios; character recognition means for performing character recognition of pixel data obtained by said compression means; compression ratio selection means for selecting one of a plurality of predetermined compression ratios based on a predetermined threshold value and recognition result from said character recognition means; and transmission means for transmitting, to an external device, pixel data obtained by compressing the pixel data of the character image block by said compression means at the compression ratio selected by said compression ratio selection means, wherein the predetermined threshold value represents a minimum compression ratio such that, when an image represented by the pixel data of the character image block is reconstructed by the external device based on the pixel data transmitted by said transmission means, the image can be recognized as a character by a user.
