Camera Image Cropping Using Face Detection and Automatic Crop Marks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera devices and portable terminals require additional image editing programs for cropping photos, which can lead to inconvenient manual cropping and may result in cutting off desired subjects, especially when multiple people are in the photo.
Innovation Solution
An apparatus and method that recognizes face areas in images and sets a crop mark to include all faces, allowing for automatic cropping centered on individuals, even when multiple people are in the photo, using a control unit with face recognition capabilities and a display unit for visual feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a default crop area is used in camera devices, then the cropping operation is simple and quick, but the face may be cut off or the crop area does not adapt to multiple persons
Solution Approach 1:
The system performs face detection and recognition before the cropping operation to identify all face areas in the image. Based on these pre-identified face areas, the control unit automatically determines and sets an appropriate crop area that includes all detected faces, eliminating the need for manual adjustment while ensuring accuracy.
Solution Approach 2:
The camera device automatically performs face detection, recognition, and crop area determination without requiring user intervention. The system serves itself by autonomously identifying faces and setting the crop area, combining the simplicity of automatic operation with the precision of face-aware cropping.
2Manufacturing precision
If manual cropping using image editing programs is performed, then the crop area can be precisely controlled, but the process requires additional software and manual effort
Solution Approach 1:
The patent combines face detection, face recognition, and cropping functions into a single integrated system within the camera device. By merging these functions, the device achieves precise face-centered cropping without requiring external image editing programs, thereby maintaining precision while reducing overall system complexity.
Solution Approach 2:
The camera device is enhanced with multi-functionality by incorporating face detection and recognition capabilities alongside the existing cropping function. This universal approach allows the device to automatically adapt the crop area based on detected faces, providing precise cropping without requiring separate image editing software.
3Adaptability or versatility
If the crop area is enlarged to include all persons in a group photo, then all faces are included in the crop, but the desired focus on individual faces is lost
Solution Approach 1:
The system segments the crop area determination process by first detecting and identifying individual face areas, then determining a crop area that includes all detected faces. This segmentation allows the system to adapt to different scenarios (single person vs. multiple persons) while maintaining face centering accuracy through calculated crop regions based on detected face positions.

AI summary
A method of cropping an image in an apparatus having a camera includes displaying an image, identifying a face area in the image if a crop mode is selected, setting and displaying a crop mark including the identified face area, and displaying a crop image by cropping an image in the crop mark if a crop execution is requested.
