Image Deformation Exclusion Logic for Multifunction Printers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies for deformation are complex and inefficient, particularly when handling images that extend beyond cropped areas, leading to increased processing loads and memory consumption, especially in multifunctional devices like printers.
Innovation Solution
An image processing device with a candidate area setting unit, exclusion determination unit, and deformation processing unit that selectively targets areas for deformation based on predetermined conditions, such as aspect ratios, size, and orientation, to reduce processing and memory burdens by excluding areas that extend beyond cropped images or overlap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image deformation is performed on all detected faces in the target image, then comprehensive deformation processing is achieved, but processing load and memory consumption increase significantly
Solution Approach 1:
The patent extracts and processes only the necessary portions of the image (candidate areas containing faces) while excluding irrelevant areas. By identifying candidate areas that may extend beyond cropped images and selectively processing only those, the system reduces overall processing load while maintaining comprehensive deformation coverage where needed.
Solution Approach 2:
The patent applies different processing strategies to different regions of the image. Candidate areas are identified based on their potential to extend beyond cropped images, and deformation processing is applied selectively to these specific regions rather than uniformly to the entire image, optimizing the balance between processing coverage and computational load.
2Reliability
If image deformation is performed on candidate areas extending beyond cropped images, then complete deformation processing is achieved, but memory consumption increases due to buffer requirements
Solution Approach 1:
The patent performs preliminary identification of candidate areas before deformation processing. By pre-determining which areas may extend beyond cropped images and excluding them from deformation processing, the system avoids allocating memory buffers for areas that will not be processed, thereby reducing memory consumption while maintaining processing completeness for relevant areas.
3Adaptability or versatility
If all faces in the target image are processed for deformation, then all deformation targets are handled, but processing time increases
Solution Approach 1:
The patent extracts and processes only the necessary portions of the image (candidate areas containing faces) while excluding irrelevant areas. By identifying candidate areas that may extend beyond cropped images and selectively processing only those, the system reduces overall processing time while maintaining comprehensive deformation coverage where needed.

AI summary
An image processing device that executes deformation of an image. A candidate area setting unit sets candidate areas, each of which includes a specific image, on a target image used as a target for a deformation process. An exclusion determination unit, when there is a candidate area that partially extends off a cropped image that is clipped from the target image through predetermined cropping, excludes the candidate area, which at least partially extends off the cropped image, from the target for the deformation process. A deformation processing unit performs deformation of an image on the candidate areas other than the excluded candidate areas.
