Selective Image Data Reading via Address Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable devices face excessive bandwidth and power consumption when reading entire image data, even for displaying excerpts, due to the need to read entire high-resolution images, which results in wasteful data transfer and energy use.
Innovation Solution
A method and apparatus that set first addresses for a full image and second addresses for a blocking region within the image, allowing the system to bypass reading data from the blocking region by either stopping or jumping over it during the data read process, using a special function register to manage these addresses and control the data processing circuit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the entire image data is read to display an excerpted blocking region, then the complete image data is available for processing, but bandwidth is wasted and power consumption increases
Solution Approach 1:
The patent divides the image data into two segments: the full image data and the blocking region data. By setting first addresses for the full image and second addresses for the blocking region, the system can selectively process only the necessary blocking region portion while excluding unnecessary full image data, thereby reducing power consumption and improving data transfer efficiency
Solution Approach 2:
The patent extracts only the necessary blocking region data from the complete image data by using address setting mechanisms. The data processing circuit is configured to read only the blocking region data corresponding to the second addresses while bypassing the rest of the full image data, thus eliminating wasted bandwidth and reducing power consumption
2Quantity of substance
If the entire image data is read to display an excerpted blocking region, then the complete image data is available for processing, but bandwidth is wasted
Solution Approach 1:
The patent segments the image data into full image data and blocking region data using address settings. By configuring the data processing circuit to operate on segmented data (only blocking region), the system reduces the quantity of data transferred while maintaining productivity
Solution Approach 2:
The patent extracts only the blocking region data from the full image using address-based selection. This extraction mechanism ensures that only the necessary data quantity is transferred, eliminating bandwidth waste while preserving data transfer efficiency
3Speed
If address jumping is implemented to bypass blocking region, then reading speed improves, but address management complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-setting the first and second addresses in a special function register before the reading operation begins. This preliminary address configuration enables the data processing circuit to automatically bypass the blocking region through address jumping without requiring complex real-time address management during execution, thus improving reading speed while keeping address management simple

AI summary
A method of reading data includes setting first addresses defining a full image and second addresses defining a blocking region included in the full image and not reading blocking region data corresponding to the blocking region among image data corresponding to the full image using the first addresses and the second addresses.
