Abstract: Provided is an image processing device used for image processing in an image forming device that executes linear image forming in a first direction repeatedly in a second direction orthogonal to the first direction and executes two-dimensional image forming on a recording medium, the image processing device including: a processor configured to: acquire a phase of a member that contributes to image forming by rotating or circulating in the second direction and calculate, for each of different phases, an input/output gradation characteristic indicating a correspondence relationship in density in the same pixels in pre-output image data and post-output image data acquired by scanning of an image formed on the recording medium; calculates correction data to solve a difference between the input/output gradation characteristic in each of the phases and a reference input/output gradation characteristic; and correct the pre-output image data with the correction data of each of the phases.

Abstract: An image inspecting apparatus includes a reader that reads an image on a recording material formed in an image forming apparatus and generates read image data and an image analyzer that performs analysis to determine abnormality for the read image data by using a threshold value and creates an analysis result. The image analyzer makes pixels constituting the read image data a target pixel sequentially and performs determination of abnormality for the target pixel by using the threshold value calculated by using a threshold value calculating method. The threshold value calculating method includes a plurality of threshold value calculating methods, and a first threshold value calculating method is switched to other threshold value calculating method correspondingly to a number of pixels included in a region for calculating a threshold value.

Abstract: An image inspection apparatus includes: an image reader that reads an original image on a recording material based on a print job and generates a read image; and a hardware processor that analyzes the read image acquired from the image reader and performs image inspection, in which the hardware processor: performs predetermined filter processing on the read image and generates a first reference image; acquires background density from the first reference image and sets a threshold based on the background density; compares the read image to the first reference image and generates a first comparison image; and binarizes the first comparison image by using the threshold, detects a part where a specific abnormality has occurred, and outputs a detection result.
