Abstract
A system for predicting occurrence of a defective image includes an observation distance obtainer which obtains an observation distance of an image to be formed by an image forming apparatus. The system (i) divides image data input to the image forming apparatus as an original of the image into regions of interest having a size determined based on the observation distance, (ii) analyzes a spatial frequency of a gradient distribution of the image with respect to each of the regions of interest, and (iii) calculates a probability of a target density irregularity being conspicuous in the image to be formed by the image forming apparatus based on the image data by using a correlation index between a result of the analysis and an evaluation value of the density irregularity.
