Imaging Element Parallel Processing for Preview and Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices face challenges in generating preview images in real time, especially when handling high-definition large-capacity images or multiple images simultaneously, leading to increased processing loads and potential interruptions in image display.
Innovation Solution
The proposed imaging element includes a pixel unit, a generation processing unit that generates a lower-resolution image from a high-resolution image, and an output processing unit that identifiably outputs both images, allowing for parallel processing and reduced load on the output destination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-definition large-capacity images are recorded, then image quality is improved, but processing load increases and preview image generation is interrupted
Solution Approach 1:
The patent divides the image processing into two separate processing paths: one for high-definition recording images and another for preview images. The imaging element simultaneously generates both full-resolution images for recording and down-sampled preview images, allowing parallel processing without interference. This segmentation resolves the contradiction by enabling both high image quality recording and real-time preview generation to occur simultaneously through dedicated processing channels.
2Productivity
If multiple images are continuously recorded, then recording capacity is improved, but processing load increases and real-time display is interrupted
Solution Approach 1:
The imaging element performs preliminary down-sampling to generate preview images at the point of image capture, before the images reach the output destination for recording. By pre-processing and generating preview images in real-time during the imaging process, the system eliminates the need for post-capture processing, thereby preventing display interruptions and maintaining continuous real-time preview capability even when multiple high-definition images are being continuously recorded.
3Adaptability or versatility
If zoom images and preview images are generated and displayed simultaneously, then functionality is improved, but processing load increases and display is interrupted
Solution Approach 1:
The patent implements separate processing paths for different image types: full-resolution images for recording, down-sampled preview images for display, and cropped zoom images. Each image type is processed through its dedicated channel with appropriate processing applied at the imaging element level. This segmentation allows simultaneous generation of multiple image types without processing conflicts, maintaining both functional versatility and real-time generation capability.
Solution Approach 2:
The imaging element performs preliminary processing to generate preview images and zoom images directly at the point of capture, before output to the destination device. By pre-generating these processed images during the imaging process itself, the system reduces the processing burden on the output destination and enables simultaneous display of multiple image types without interruptions.
