Digital Signal Processor Face Image Skin Condition Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital image processors lack the capability to effectively measure and improve the skin condition of detected faces in images, particularly in live view images, leading to unsatisfactory image quality due to rough skin features like freckles and wrinkles.
Innovation Solution
A digital signal processor is integrated into the digital image processor to perform face recognition, measure skin condition, and correct rough skin portions by adjusting brightness levels based on measured skin conditions, allowing for real-time correction and user-controlled image enhancement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If face recognition and skin condition measurement are added to the digital image processor, then image quality is improved, but device complexity increases
Solution Approach 1:
The patent combines face recognition, skin condition measurement, and skin correction functions into a single integrated digital image processor. The controller coordinates these multiple functions within one device, merging what could have been separate systems into a unified processor that handles all tasks sequentially or simultaneously.
Solution Approach 2:
The digital image processor is designed as a multi-functional device that performs not only basic image capture but also face recognition, skin condition measurement, skin correction, and image capture. This universal device replaces what would traditionally require multiple separate tools or post-processing steps.
2Ease of operation
If skin condition correction is performed in real-time on live view images, then user satisfaction is improved, but processing time increases
Solution Approach 1:
The controller performs skin condition measurement and correction calculations on the live view image before the user actually captures the photo. This preliminary processing allows the system to prepare the corrected image in advance, so when the user presses the shutter button, the corrected image is already ready or can be quickly finalized.
Solution Approach 2:
The system dynamically adjusts the correction level based on user input and skin condition measurement results. The controller can modify correction intensity, apply different correction algorithms, or adjust processing priorities in real-time based on the specific skin conditions detected and user preferences, optimizing processing efficiency for each case.
