Solution Overview
Problem
High-resolution image capture in digital cameras leads to increased data processing time, affecting the speed of image output, analysis, and processing, as the amount of data to be processed and displayed on the camera's display unit increases.
Innovation Solution
An information processing device and method that processes and outputs image data with different densities, utilizing a frame memory to temporarily store high-resolution image signals and output low-resolution images first for preview, allowing for parallel processing and reduced transfer volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of pixels in the image sensor is increased to capture high-resolution images, then the resolution of captured images is improved, but the amount of data to be processed increases, causing processing time to increase
Solution Approach 1:
The patent segments the image data into two types: first data at lower resolution and second data at higher resolution. The image sensor outputs first data from all pixels and second data from selected pixels, allowing the processor to handle different resolution levels separately and reduce overall processing time while maintaining high-resolution capability when needed.
Solution Approach 2:
The patent applies local quality by providing different data densities to different processing needs. The image sensor outputs first data with lower data density for general processing and second data with higher data density for high-resolution requirements, allowing quality to be optimized locally for different purposes rather than uniformly across all processing tasks.
2Measurement precision
If high-resolution images are captured to improve image quality, then the detail and clarity of images is improved, but the time required for image output and processing increases
Solution Approach 1:
The patent segments image processing into two parallel paths: one for first data (lower resolution) and one for second data (higher resolution). This segmentation allows the system to maintain high image quality through second data while improving productivity by processing first data more quickly for immediate output needs.
Solution Approach 2:
The patent performs preliminary action by outputting first data at lower resolution before completing second data processing. The image sensor outputs first data from all pixels first, allowing quick preview and preliminary processing, then outputs second data from selected pixels for high-resolution requirements, thereby improving overall image output speed while maintaining quality optionality.
3Measurement precision
If all pixel data is processed to maintain high resolution, then image detail is preserved, but the data transfer volume and processing load increase
Solution Approach 1:
The patent segments data processing by outputting first data from all pixels for basic processing and second data from selected pixels for high-resolution needs. This segmentation reduces the processing load by avoiding unnecessary processing of all high-resolution data when only lower-resolution output is required, while preserving image detail capability when needed.
Solution Approach 2:
The patent applies partial action by outputting second data from only selected pixels rather than all pixels, when high resolution is not required. This partial processing approach reduces device complexity and processing load while maintaining the capability to provide high-resolution images when necessary, avoiding excessive processing of all pixel data.
