De-squeezed Image Processing Using Buffer Memory and Region Enlargement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Anamorphic lenses cause distortion at the left and right ends of captured images, leading to incomplete de-squeezing processes due to time constraints at high frame rates, where the existing methods of cutting off image sides result in reduced processing time and potential failure to generate de-squeezed images within the required time frame.
Innovation Solution
An image processing apparatus that acquires a captured image, records it, and then enlarges a predetermined region horizontally or vertically, allowing for extended processing time by utilizing image data from previous frames, thereby ensuring complete de-squeezing without time constraints, even at high frame rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the entire region of the input image data is used for de-squeeze process, then the manufacturing precision is improved, but the productivity deteriorates due to insufficient processing time at high frame rates
Solution Approach 1:
The patent applies preliminary action by storing the captured image data in a buffer memory before performing the de-squeeze process. This allows the system to prepare the image data in advance, so that when the de-squeeze operation is needed, the data is already available and ready for processing. This resolves the contradiction by enabling full-image de-squeezing (maintaining precision) while the buffer provides the necessary time buffer for processing (maintaining productivity at high frame rates).
Solution Approach 2:
The patent segments the image processing into distinct stages: capturing image data, storing it in buffer memory, and then performing the de-squeeze process. This segmentation allows the system to handle the computationally intensive de-squeeze operation separately from the capturing process, enabling full-resolution de-squeezing without compromising frame rate performance.
2Productivity
If part of the input image data is cut out for de-squeeze process, then the productivity is improved by reducing processing time, but the manufacturing precision deteriorates due to incomplete de-squeezing
Solution Approach 1:
By storing the complete image data in buffer memory before processing, the system performs preliminary action that preserves all image information. This enables the de-squeeze process to work on the entire image rather than cut portions, maintaining precision while the buffer timing allows sufficient processing speed for high frame rates.
3Manufacturing precision
If the de-squeeze process is performed on the entire image, then the manufacturing precision is improved, but the loss of time increases making it impossible to complete processing within the frame time
Solution Approach 1:
The buffer memory stores the captured image data in advance, performing preliminary action that prepares the data for de-squeezing. This timing arrangement ensures that the complete image can be processed with full precision while the buffer provides the necessary time buffer to complete processing within the frame time constraints of high frame rate operation.
Solution Approach 2:
The buffer memory acts as an intermediary between the image capturing and de-squeezing processes. It temporarily holds the complete image data, allowing the de-squeeze operation to access and process the entire image without time pressure, thereby maintaining precision while fitting within the frame time budget.

AI summary
An image processing apparatus includes: an acquisition unit configured to acquire a captured image of 1 frame as an Nth frame image; and a control unit configured to (1) record the Nth frame image in a memory, (2) enlarge an region having a predetermined aspect ratio in a horizontal direction wherein the region is a part of an image of a frame prior to the Nth frame recorded in the memory, and (3) display the enlarged region, within a period in which the Nth frame image is acquired and recorded.
