Innovation Solution
An electronic device with multiple operating modes, featuring an illumination module, image projection module, and camera module, controlled by a processor that adjusts light color temperature and functionality based on user instructions, including medium color temperature for projection, high color temperature for photography, and low color temperature for reading, while dynamically adjusting brightness to minimize ambient light interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a built-in camera module is used for photographing, then image capturing function is improved, but ambient light interference causes deterioration of image quality
Solution Approach 1:
The patent converts the harmful ambient light into a beneficial illumination source for photography. By using the projected light (which includes ambient light components) to illuminate the photographing subject, the system transforms the interfering ambient light into a useful lighting source, thereby improving image capturing quality while eliminating the need for separate flash or lighting equipment.
Solution Approach 2:
The projected light serves multiple functions simultaneously: it acts as both the projection display medium and the illumination source for the camera module. This multi-functionality allows the same light source to be used for both projecting images and illuminating subjects for photography, resolving the contradiction by making the light source serve dual purposes.
2Adaptability or versatility
If image projection module is used for projection, then projection function is improved, but manual operation requirement causes deterioration of ease of operation
Solution Approach 1:
The system automatically determines whether to enter projection mode or photography mode based on receiving a photographing instruction, without requiring manual switching or configuration by the user. The processor autonomously controls the switching between modes and coordinates the various modules (projection module, camera module, illumination module) based on the received instruction, thereby improving ease of operation while maintaining projection functionality.
Solution Approach 2:
The system performs preliminary configuration and mode switching automatically upon receiving a photographing instruction, before the actual photography operation begins. This preliminary automated setup eliminates the need for manual operation during the critical photography moment, improving ease of operation while preserving full projection capabilities.
3Device complexity
If manual switching between projection and photography modes is required, then device complexity is reduced, but usage scenarios are limited causing deterioration of adaptability
Solution Approach 1:
The system dynamically switches between projection mode and photography mode based on real-time user instructions and operational context. Rather than requiring manual pre-configuration or being limited to fixed modes, the system adapts its operational state dynamically, allowing seamless transitions between different usage scenarios while maintaining relatively simple device architecture.
Solution Approach 2:
The system changes operational parameters (such as the state of the projection module, camera module, and illumination module) based on the received photographing instruction. By dynamically adjusting these parameters and module states, the system expands its usage scenarios and adaptability without significantly increasing device complexity, as it uses the same hardware components in different configurations.

AI summary
An electronic device includes an illumination module, an image projection module, a camera module and at least one processor. The processor, coupled to the illumination module, the image projection module and the camera module, determines that the electronic device executes a first or second operating mode according to an operation instruction of a user. When the first operating mode is executed, the processor enables the illumination module to generate a medium color temperature light, simultaneously enables the image projection module to project a window screen onto a plane, and allows the use to operate the window screen on the plane. When the second operating mode is executed, the processor enables the illumination module to generate a high color temperature light, simultaneously enables the image projection module to project a preset pattern onto the plane, and turns on the camera module to allow the user to take photo or image.
