1Area of stationary object
If an image is projected onto multiple surfaces bent at a defined angle to expand the projection area, then the projection area is expanded, but distortion occurs in the projected image due to changes in viewing position
Solution Approach 1:
The system dynamically adjusts pixel values based on detected viewing position changes. The processor continuously receives control signals from the remote control device indicating viewing position, and updates the pixel values of the image to be projected in real-time, transforming the static projection system into a dynamic one that adapts to changing viewing conditions.
Solution Approach 2:
The system changes the parameters of the projected image (pixel values) in response to viewing position changes. By modifying the pixel values according to the detected viewing position, the system compensates for geometric distortion and maintains image accuracy across different viewing angles and positions.
2Manufacturing precision
If the projector outputs an image corrected for one viewing position, then the image is accurate at that position, but distortion occurs when viewed from other positions
Solution Approach 1:
The system implements a feedback mechanism where the remote control device detects the actual viewing position and sends control signals back to the projector. The processor uses this feedback information to continuously adjust and update the pixel values, creating a closed-loop system that maintains image accuracy across multiple viewing positions.
Solution Approach 2:
The projection system transitions from a static corrected image to a dynamic adaptive image that changes in real-time based on viewing position feedback. The processor continuously updates pixel values in response to control signals, enabling the system to adapt to different viewing positions while maintaining image accuracy.

AI summary
The disclosure relates to an image projection device and method that corrects an image to be projected onto multiple surfaces forming a defined angle considering a viewing position. The image projection device may output an image to be projected onto a projection area including an image display area where an image is to be substantially displayed in a projection surface including at least two surfaces bent at a defined angle with respect to a corner. The image projection device may receive a control signal for changing a view point of viewing the projection area from a remote control device and update pixel values of the image to be projected, corresponding to projection points of the projection area in response to the control signal.
