Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display systems experience frame delay due to encoding and decoding processes, which limit the color space of image output and fail to fully utilize the potential of image-capturing elements, resulting in delayed image display and reduced color recognition.
Innovation Solution
A display system that processes and outputs image data in line units, performing image processing on a predetermined number of line images before displaying a frame, eliminating the need for encoding and decoding, and allowing for frame unit processing to reduce delay and enhance color recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If encoding and decoding processes are performed to convert image data into sRGB color space format, then the image data can be displayed on conventional display apparatus, but the processing time increases causing frame delay
Solution Approach 1:
The patent segments the image data processing by handling each line image independently and processes only the necessary portions of the frame. By dividing the frame into multiple line images and processing them sequentially with a line buffer, the system avoids the need to wait for complete frame encoding and decoding, thereby reducing frame delay while maintaining color space compatibility through selective processing.
Solution Approach 2:
The patent implements preliminary action by performing image processing on line images before they are fully captured or while the rest of the frame is still being captured. The line buffer stores intermediate line images, allowing the image processor to begin processing early lines while subsequent lines are being captured, thus reducing the overall processing time and frame delay.
2Manufacturing precision
If image processing is performed on complete frame images, then frame unit processing can be achieved, but the processing time increases further causing additional frame delay
Solution Approach 1:
The patent segments the frame processing into multiple line image units that can be processed independently and in parallel. By using a line buffer to store individual line images, the system can process multiple lines simultaneously or in an overlapping manner, reducing the total processing time while maintaining frame unit processing accuracy through proper synchronization and buffer management.
Solution Approach 2:
The patent ensures continuity of useful action by maintaining a line buffer that continuously stores incoming line images while the image processor continuously processes them. This overlapping of data acquisition, buffering, and processing operations eliminates idle time and ensures that the image processing pipeline operates continuously without waiting for complete frame accumulation, thereby reducing processing time while maintaining accuracy.
3Ease of manufacture
If encoding is performed per frame image, then data can be output in a standardized format, but the frame delay of at least one frame is inevitable
Solution Approach 1:
The patent segments the encoding process by applying encoding to individual line images or small groups of lines rather than waiting for complete frames. The line buffer stores these encoded line images, which can then be assembled into complete frames for display. This segmentation allows encoding to begin immediately on available data, eliminating the mandatory one-frame delay while maintaining standardized output format through consistent encoding application.
4Adaptability or versatility
If the color space is limited to sRGB, then compatibility with display apparatus is ensured, but the potential in color recognition of the image-capturing element is not exploited
Solution Approach 1:
The patent performs color space conversion as a preliminary action during the line image processing stage, converting captured color data to sRGB format before the images are fully captured or displayed. By performing this conversion early on individual line images rather than waiting for complete frames, the system preserves full color information from the image-capturing element while ensuring display compatibility, avoiding the information loss that would occur from limiting the color space at the capture stage.

AI summary
The display system includes a display system including an image-capturing apparatus including an image-capturing element; an image processing apparatus that performs image processing on the image; and a display apparatus including a display device that displays the image resulting from the image processing. The image processing apparatus includes an image processor that performs the image processing on a predetermined number of line images corresponding to a part of a frame image captured by the image-capturing element, sequentially outputs the image to the display apparatus per the predetermined number of line images, and causes the display apparatus to display the frame image; and a storage device that stores the predetermined number of line images until the frame image is completed. The image processor is configured to perform the image processing including frame unit processing on the predetermined number of line images associated with the frame image to be output.
