Image Driving Device Partial Frame Processing Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing methods fail to effectively reduce drive time and power consumption, often adversely affecting host electronic devices.
Innovation Solution
An image driving device that determines whether an input image is still or moving, processing accordingly by comparing representative values of consecutive frames and adjusting the number of frames processed and stored, with a memory that refreshes based on the image type, optimizing power usage and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If all frames of the input image are image-processed, then the completeness of image processing is improved, but the power consumption and drive time increase
Solution Approach 1:
The patent applies partial action by processing only a subset of frames rather than all frames. The determining unit identifies still images by comparing consecutive frames, and when a still image is detected, the image processing unit processes only one or several selected frames instead of all frames, thereby reducing power consumption while maintaining adequate processing completeness
Solution Approach 2:
The patent implements dynamic adjustment of processing strategy based on image type detection. The system transitions between two operational modes: full frame processing for moving images and partial frame processing for still images. This dynamic adaptation allows the system to optimize power consumption according to the actual content being processed
2Manufacturing precision
If all frames of the input image are image-processed, then the completeness of image processing is improved, but the drive time increases
Solution Approach 1:
The patent reduces drive time by applying partial action - processing only necessary frames. The determining unit detects still images through frame comparison, and the image processing unit accordingly processes only one or several frames instead of all frames, directly reducing the time required for image processing operations
Solution Approach 2:
The system dynamically adjusts processing duration based on image type. For still images, processing is completed in less time by handling fewer frames, while moving images receive full processing. This dynamic time management resolves the contradiction between processing completeness and drive time
3Measurement precision
If consecutive frames are continuously compared to determine image type, then the accuracy of image type detection is improved, but the power consumption increases
Solution Approach 1:
The patent uses partial comparison action to balance detection accuracy and power consumption. The determining unit compares representative values (such as check sums or data sums) of consecutive frames to detect still images. Once a still image is detected, continuous comparison can be reduced or stopped, maintaining adequate detection accuracy while reducing power consumption

AI summary
An image driving device includes a determining unit, and image processing unit, and a memory. The determining unit determines whether an input image is a moving image or a still image, and may be synchronized with an internal clock different from an external clock. The image processing unit may image-process at least one frame but less than all frames of the input image when the input image is determined to be a still image. The image processing unit may output the at least one image-processed frame as first image data, and the memory may store the first image data.
