Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical mirrors are limited by fixed optical properties, leading to aberrations such as distortions and the inability to easily view objects from different angles, requiring multiple mirrors and challenging lighting conditions, which can result in misleading images.
Innovation Solution
A digital mirror system with a built-in image sensor and processor that captures and displays images in true or mirror view modes, allowing users to select lighting and camera angles, and store images for later viewing, using multiple cameras for comprehensive views and adjustable lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional optical mirrors are used, then the structure is simple and easy to manufacture, but the optical properties are fixed and cannot be modified, leading to aberrations and distorted images
Solution Approach 1:
The patent replaces the optical mirror with a digital camera and display system that captures and reproduces the user's image. The camera captures the user's appearance and displays it on a screen, eliminating optical aberrations and distortions inherent in physical mirrors while maintaining the basic function of self-viewing.
Solution Approach 2:
The patent substitutes the mechanical/optical mirror system with an electronic imaging system. Instead of relying on reflective surfaces and optical properties, the system uses a digital camera sensor, image processor, and display to capture and present the user's image, thereby eliminating fixed optical constraints.
2Adaptability or versatility
If multiple optical mirrors are used to view objects from different angles, then comprehensive views are achieved, but the device complexity and space requirements increase
Solution Approach 1:
The patent introduces a movable camera mechanism that can rotate and capture images from multiple angles. Instead of requiring multiple fixed mirrors arranged in specific geometries, a single camera unit moves through angular dimensions to capture comprehensive views that can be displayed sequentially or simultaneously.
Solution Approach 2:
The digital mirror system performs multiple functions with a single device: it captures front views, side views, and back views; provides lighting; displays images; and allows angle adjustment. This multi-functional approach replaces the need for multiple specialized optical mirrors.
3Illumination intensity
If multiple light sources are used to illuminate the object properly, then clear views are achieved, but the device complexity and energy consumption increase
Solution Approach 1:
The patent integrates the lighting function directly into the mirror housing, combining illumination sources with the imaging and display system. This unified approach provides necessary lighting for image capture while consuming less energy than multiple separate lighting systems would require.
Solution Approach 2:
The system automatically activates lighting when the camera or display is in use, eliminating the need for separate manual lighting control. The lighting serves the imaging function directly, providing illumination only when needed for image capture or viewing.
4Measurement precision
If conventional optical mirrors are used, then the structure is simple, but the ability to view true colors and accurate details is compromised due to optical aberrations
Solution Approach 1:
The digital camera captures the user's image with high fidelity, recording true colors and accurate details without the optical distortions that affect physical mirrors. The digital copy preserves the authenticity of the user's appearance while eliminating aberrations inherent in optical reflection systems.
Data Source
AI summary
In one aspect, a method provides a display device. The method senses the presence of the user or scene change within the field of view of the system's image sensor with a built-in image signal processor. The method automatically and concurrently powers on the image sensor. The method lights one or more lights around the display device in response to sense the presence of the user or scene change. The method captures one or more frames of images of a user or scene change with the image sensor. Each frame includes an M by N array of pixel data. The M by N array of pixel data comprises a data structure consisting of a collection of pixel elements enumerated as pixel P11 to pixel Pm1. The method stores the M by N array of pixel data as a frame of data written into a frame buffer memory of the display device.
