Display Control Apparatus Anamorphic Image Resizing Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for displaying images captured using an anamorphic lens face challenges when the recording frame rate increases, leading to potential delays in displaying captured images, which can result in incomplete or delayed image output due to the time required for resizing and processing.
Innovation Solution
A display control apparatus and method that performs desqueeze processing, including first and second desqueeze processing, to efficiently handle image resizing and display, even at higher frame rates, by clipping and scaling image data to maintain image quality and ensure timely display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image resizing and processing is performed to display captured images using an anamorphic lens, then image quality and aspect ratio are improved, but processing time increases causing delays in image output
Solution Approach 1:
The system performs preliminary clipping of the captured image to extract only the necessary portion before resizing. This preliminary action reduces the amount of data that needs to be processed during the resizing operation, thereby decreasing processing time while maintaining image quality for the displayed portion.
Solution Approach 2:
The image processing is divided into two distinct stages: first clipping the image to the required display area, then resizing only the clipped portion. This segmentation allows each process to operate on optimized data sizes, improving overall processing efficiency and reducing total processing time.
2Productivity
If recording frame rate is increased during moving image capturing, then productivity and capture speed are improved, but image display becomes incomplete or delayed due to processing time requirements
Solution Approach 1:
By clipping the image before resizing, the system prepares the data in advance in a format that requires minimal processing for display. This preliminary preparation enables the system to handle higher frame rates by reducing the computational burden per frame, ensuring complete and timely image display even at increased productivity levels.
Solution Approach 2:
The system performs clipping to extract only the necessary display area rather than processing the entire captured image. This partial action approach processes only the essential portion of the image at high frame rates, ensuring reliable display completeness while maintaining high productivity.
3Loss of information
If the entire captured image is resized without clipping, then complete image data is preserved, but processing time increases causing delays
Solution Approach 1:
The system extracts only the necessary display area from the full captured image through clipping before resizing. This extraction eliminates unnecessary data processing while preserving all essential image information required for display, thereby reducing processing time without losing critical image data.
Solution Approach 2:
Instead of resizing the entire captured image, the system performs partial processing by resizing only the clipped display area. This partial action maintains complete image data for the displayed portion while significantly reducing the processing time required.

AI summary
A display control apparatus (100) is capable of acquiring first image data on a subject image formed at different magnifications in horizontal and vertical directions. The display control apparatus (100) performs first resizing comprises applying first processing to obtain second data by clipping a part of the first image data and then generating a display image having a predetermined aspect ratio from the second data in a case where a moving image recording setting satisfies a predetermined condition. The display control apparatus (100) performs second resizing comprising resizing the first image data without applying the first process in a case where the moving image recording setting does not satisfy the predetermined condition.
