High-Resolution Still Image Transmission via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing technologies are limited in transmitting and displaying still images with resolutions higher than full HD, as HDMI cables can only support full HD resolution, preventing the transmission of higher resolution still images and requiring scaling of both still and moving images, which affects the display quality.
Innovation Solution
An image processing apparatus comprising a receiver and a display device that divides high-resolution still images into lower resolution components for transmission, while maintaining the higher resolution for display, using a multiprocessor to generate divisional still images and positional information for accurate placement on the display, and a scaling processor to convert moving images to higher resolutions, allowing for the display of still images with resolutions higher than full HD.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If HDMI cable is used for transmission, then compatibility and ease of operation are improved, but the resolution is limited to full HD
Solution Approach 1:
The high-resolution still image is divided into multiple divisional still images with lower resolution that can be transmitted through the HDMI cable. This segmentation allows the image to be broken down into transmittable units while preserving the original high-resolution data for later reconstruction on the display device.
Solution Approach 2:
The patent introduces a temporal dimension to the transmission process. Instead of transmitting the entire high-resolution image at once, it transmits divisional images sequentially over time, with positional information indicating where each divisional image should be placed. This allows high-resolution display through standard HDMI infrastructure.
2Adaptability or versatility
If scaling is performed on still image, then transmission through HDMI cable is enabled, but display quality deteriorates
Solution Approach 1:
Instead of scaling the entire still image, the patent segments it into divisional still images that match the HDMI transmission resolution. This avoids quality loss from scaling while enabling transmission through standard interfaces.
Solution Approach 2:
The still image is pre-processed by dividing it into multiple lower-resolution divisional images before transmission. This preliminary segmentation prepares the image for HDMI transmission without quality loss, and the original high-resolution data is preserved for reconstruction at the display device.
3Manufacturing precision
If high-resolution still image is transmitted, then display quality is improved, but transmission compatibility is reduced
Solution Approach 1:
The high-resolution still image is divided into multiple divisional still images with resolution suitable for HDMI transmission. This segmentation maintains transmission compatibility while preserving the ability to reconstruct the original high-resolution image on the display device using positional information.
4Adaptability or versatility
If still image is divided into multiple images, then transmission through HDMI cable is enabled, but device complexity increases
Solution Approach 1:
The image processing apparatus performs multiple functions: it divides the still image into divisional images, generates positional information, transmits both via HDMI, and reconstructs the original high-resolution image on the display device. This multi-functionality is achieved within a unified system architecture that manages complexity through integrated processing.

AI summary
According to one embodiment, an image processing apparatus includes a receiver, a display device, and a transmission module. The receiver includes a video receiver, a video processor, a graphics processor, and a multiprocessor. The video processor converts the video signal received by the video receiver to a moving image with a first resolution. The graphics processor outputs a still image with a second resolution higher than the first resolution according to an instruction. The multiprocessor divides the still image into divisional still images with the first resolution. The display device includes a display module, a scaling processor, a restoration processor, and a blend processor. The scaling processor scales the moving image with the first resolution. The restoration processor restores the divisional still images to the original still image. The blend processor displays the moving image and the still image with the second resolution on the display module.
