Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As image resolution increases, conventional image-data-processing devices face challenges in storing and processing high-resolution image data due to increased storage space and processing memory bandwidth requirements, which often exceed the physical dimensions of the device, necessitating larger memory capacity while maintaining existing dimensions.
Innovation Solution
The solution involves an image-data-processing device with an image processing chip that includes a data managing unit, a coding module, and two memories: an internal memory for operational data and an external memory for storing high-resolution image data, connected through a connection unit to allow flexible memory allocation and maintain device dimensions.

Engineering Contradiction Analysis
1Quantity of substance
If additional SRAM is added to increase memory capacity for high-resolution image data, then memory capacity is improved, but device dimensions exceed physical space limits
Solution Approach 1:
The memory system is segmented into two distinct parts: an internal memory (first memory) within the image-data-processing device for operational data, and an external memory (second memory) connected via communication interface for high-resolution image data storage. This segmentation allows the device to access additional storage capacity without increasing its physical footprint, as the external memory is located outside the device's packaged dimensions.
Solution Approach 2:
A communication interface acts as an intermediary between the image-data-processing device and the external memory. This interface enables data transfer between the device's internal memory and the external memory storage, allowing the device to effectively utilize expanded capacity while maintaining its original physical dimensions through coordinated data management.
2Measurement precision
If image resolution increases, then image quality is improved, but storage space and processing memory bandwidth requirements increase
Solution Approach 1:
The storage system is divided into two parts: internal memory for operational data and external memory for high-resolution image data. This segmentation allows the device to handle high-resolution images by storing them in the external memory, thereby meeting the increased storage requirements of high-resolution imaging without compromising the device's compact design.
Solution Approach 2:
The solution moves the storage capacity dimension from within the device's physical footprint to an external dimension. By utilizing external memory connected through the communication interface, the system effectively adds storage capacity in a dimensional space outside the device's packaged dimensions, allowing high-resolution image storage without increasing the device's physical size.

AI summary
An image-data-processing device for processing first image data includes an image processing chip with a first memory and a second memory. The image processing chip further includes a data managing unit and a coding module, wherein the memory space of the second memory is greater than the memory space of the first memory. The data managing unit receives the first image data from an image sensor and transmits the image data to the encoding module, wherein the encoding module generates a second image data based on the first image data received. The data managing unit then selectively stores the second image data in the first memory or the second memory.
