IMAGE FORMING APPARATUS, CONTROL METHOD OF IMAGE FORMING APPARATUS, AND STORAGE MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18464319 titled 'IMAGE FORMING APPARATUS, CONTROL METHOD OF IMAGE FORMING APPARATUS, AND STORAGE MEDIUM
Simplified Explanation
The patent application describes a method for generating a halftone image and identifying a failure component in an image forming apparatus based on a comparison between the input image and a scanned image of a printed material.
- Halftone image is generated through halftone processing of the input image.
- Scanned image of printed material is obtained to identify failure component in the image forming apparatus.
- Dot pattern representation is used to generate the halftone image, with different frequencies for test images and other images.
Potential Applications
- Quality control in image forming apparatus.
- Diagnostic tool for identifying failure components in printing equipment.
Problems Solved
- Efficient identification of failure components in image forming apparatus.
- Improved quality control processes in printing technology.
Benefits
- Enhanced maintenance procedures for image forming equipment.
- Increased accuracy in diagnosing issues with printing devices.
Original Abstract Submitted
In the image forming method, a halftone image is generated by performing halftone processing for an input image, a scanned image of a printed material on which on which the halftone image is printed is obtained, and a failure component of an image forming apparatus is identified based on a difference between the scanned image and the input image. In the generation, the halftone image is generated by representing a dot pattern of a halftone portion in a case where the input image is a test image for the failure diagnosis by a dot pattern whose frequency is relatively higher than that of a dot pattern that is applied to the halftone portion in a case where the input image is an image other than the test image.
