Image Processing Apparatus Frame Rate Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing apparatuses require high-speed operation clocks to acquire full screen data at higher frame rates, leading to increased operational frequency and potential heat generation and EMC property deterioration.
Innovation Solution
An image processing apparatus that adjusts the frame rate based on the imaging range, using a first setting for a predetermined range at a lower frame rate and a second setting for a narrower range at a higher frame rate, allowing for flexible image processing without increasing the operation clock frequency, and includes a deviation calculation for focus adjustment.

Engineering Contradiction Analysis
1Productivity
If the operation clock frequency is increased to acquire full screen data at higher frame rates, then the frame rate is improved, but heat generation and EMC property deterioration occur
Solution Approach 1:
The imaging range is segmented into a first range (full screen) and a second range (narrower region of interest). The imaging means acquires data for the second range at a higher frame rate while maintaining a lower operation clock frequency, thereby achieving high frame rate performance for critical areas without increasing overall system frequency and avoiding heat generation and EMC issues
Solution Approach 2:
Different frame rates are applied to different regions of the imaging range. The second range (narrower range) receives higher frame rate processing while the first range maintains lower frame rate, allowing localized high-performance processing without requiring the entire system to operate at high frequency
2Speed
If the operation clock frequency is increased to process image data at higher frame rates, then the processing speed is improved, but device complexity and heat generation increase
Solution Approach 1:
The imaging means dynamically adjusts the frame rate based on the imaging range and application requirements. By switching between first frame rate (for full screen) and second frame rate (for narrower range), the system achieves variable processing speed without requiring a permanently high-speed operation clock, thereby reducing device complexity
3Productivity
If full screen data is acquired at high frame rate, then the image processing performance is improved, but the process load increases
Solution Approach 1:
The patent extracts and processes only the necessary portion of the image data. By acquiring data for the second range (narrower range) at high frame rate instead of processing the entire full screen data, the system reduces the quantity of data to be processed, thereby lowering process load while maintaining required image processing performance

AI summary
An imaging means acquires an imaged image in a predetermined imaging range for each predetermined frame rate. An image processing means performs image processing on image data of the image captured by the imaging means. A first setting means (S420) sets the imaging means to image a predetermined first range in the imaging range with a predetermined first frame rate. A second setting means (S430) sets the imaging means to image a second range, which is a part of the imaging range imaged by the imaging means and is narrower than the first range, with a second frame rate higher than the first frame rate. A determination means (S420) selects one of the first setting means and the second setting means depending on process contents that the image processing performs.
