Solution Overview
Problem
Conventional image processing systems for printing apparatuses face challenges in balancing image quality and processing speed due to inconsistent face detection definitions across devices, leading to suboptimal correction processing when using face information from Exif data, which can result in trade-offs between image quality and speed.
Innovation Solution
An image processing apparatus that acquires image data, detects image features, judges print settings, selects between detection results from an input device and the printing apparatus based on those settings, and performs correction processing to optimize image quality and speed.

Engineering Contradiction Analysis
1Manufacturing precision
If face detection processing is performed inside the printing apparatus using Exif information, then image quality is improved through accurate correction, but processing speed deteriorates due to high computational load
Solution Approach 1:
The face detection processing is performed in advance by the digital camera before printing. The detection results are stored in the Exif information of the image data, so when the printing apparatus receives the image, the face area is already identified and correction can be applied directly without performing new detection processing.
Solution Approach 2:
The face detection function is extracted from the printing apparatus and placed in the digital camera. The printing apparatus only performs the correction processing based on the pre-detected face information, separating the detection task from the correction task to optimize the printing apparatus for its core function.
2Productivity
If face detection is performed using manufacturer-specific Exif information, then processing speed is improved, but image quality deteriorates due to inconsistent face area definitions across manufacturers
Solution Approach 1:
The invention changes the parameter basis for face detection from manufacturer-specific Exif information to standardized detection results performed by the printing apparatus itself. This ensures consistent face area definitions across different manufacturers while still enabling efficient processing through standardized algorithms.
