To provide an image processing apparatus and method, and a program that appropriately perform processing of compressing an image without impairing visibility of characters included in the image.SOLUTION: An image forming apparatus 10 applied with an image processing apparatus comprises: an image input unit that reads an image of a document; a character detection unit that performs at least first character recognition processing or first character edge detection processing on the image to detect rectangles of the characters; a character size estimation unit that estimates the character size of the characters based on the detected rectangles of the characters; and an image processing unit that determines the compressibility from the estimated character size, and performs processing of outputting the image compressed based on the compressibility.SELECTED DRAWING: Figure 2 【課題】画像に含まれる文字の視認性を損なわないよう、適切に画像を圧縮する処理を行う画像処理装置、方法及びプログラムを提供する。【解決手段】画像処理装置を適用した画像形成装置１０は、原稿の画像を読み取る画像入力部と、画像に対して、少なくとも第１の文字認識処理又は第１の文字エッジ検知処理を行うことで、文字の矩形を検出する文字検出部と、検出した文字の矩形に基づき当該文字の文字サイズを推定する推文字サイズ推定部と、推定した文字サイズから圧縮率を決定し、当該圧縮率に基づき圧縮した画像を出力する処理を行う画像処理部と、を備える。【選択図】図２
