Imaging Apparatus Anamorphic Lens Aspect Ratio Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Anamorphic lenses compress images horizontally, making it difficult to accurately recognize subjects and perform processing tasks like face recognition, exposure evaluation, and white balance setting, due to issues with image quality and aspect ratio deviation during enlargement.
Innovation Solution
An imaging apparatus with a transformation unit that changes the aspect ratio of image data, allowing for accurate processing and output to display devices or recording media without distortion, using a processor to execute programs for image correction, recognition, and evaluation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an anamorphic lens is used to compress and capture a subject, then a widescreen image with aspect ratio 2.4:1 can be obtained, but it becomes difficult to accurately recognize the subject and perform processing such as face recognition, detection, and evaluation
Solution Approach 1:
The patent divides the image processing into two separate pathways: one pathway restores the horizontally compressed image for display on the finder to enable accurate subject recognition, while another pathway maintains the original compressed image for recording. This segmentation allows each pathway to serve its specific purpose optimally without compromising the other.
Solution Approach 2:
The patent applies parameter changes by horizontally enlarging the restored image by a specific ratio (e.g., 2.4x) to convert it from the compressed anamorphic format to a normal aspect ratio format suitable for recognition processing. This parameter transformation enables accurate subject recognition while preserving the original compressed image for widescreen recording.
2Measurement precision
If the horizontally compressed image is restored for display on the finder, then subject recognition is improved, but the original compressed image is needed for accurate recognition-system processing, detection-system processing and evaluation-system processing
Solution Approach 1:
The patent creates separate processing pathways for different purposes: one pathway restores and enlarges the image for finder display to aid subject recognition, while another pathway preserves the original compressed image for recording and processing. This segmentation eliminates the need to choose between recognition accuracy and processing accuracy.
Solution Approach 2:
The patent creates a restored and enlarged copy of the compressed image for display purposes, while the original compressed image remains intact for recording and processing. This copying approach allows both the restored and original images to coexist and serve their respective functions without interference.
3Measurement precision
If image data is restored to normal aspect ratio before recording, then subject recognition is improved, but image quality degrades and aspect ratio deviation occurs due to lens dispersion errors
Solution Approach 1:
The patent segments the image data handling into two distinct pathways: one pathway restores and enlarges the image for display on the finder where recognition accuracy is prioritized, while another pathway maintains the original compressed image data for recording where image quality and aspect ratio precision are preserved. This segmentation prevents quality degradation in the recorded image.
Solution Approach 2:
The patent performs the restoration and enlargement operation preliminarily only for display purposes before recording, rather than permanently altering the original image data. This preliminary action allows recognition-optimized display while preserving the original quality for recording.

AI summary
An object is to provide an imaging apparatus which can output image data whose aspect ratio or the like has not been changed, and can perform processing for setting parameters for imaging control, on the basis of image data whose aspect ratio or the like has been changed. This imaging apparatus is provided with a transformation unit that transforms image data based on an output signal of an imaging element, a processing unit that performs processing for obtaining a value to be used for a parameter for imaging control, on the basis of the image data transformed by the transformation unit, and an output unit that can output the image data based on the output signal of the imaging element to an output destination.
