Image Sensor Pixel Selection for Condition-Based Interpolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image-capturing devices struggle to handle image data obtained from areas with different image-capturing conditions uniformly, leading to inconsistencies in processing and analysis.
Innovation Solution
An image-capturing device with an image sensor that allows for setting different image-capturing conditions in various areas, using a selection unit to choose pixels for interpolation based on these conditions, and a generation unit to generate images through interpolation with selected signals, enabling uniform handling of data across varying conditions.

1Manufacturing precision
If different image-capturing conditions are applied to different areas, then image quality for each area is improved, but image data from areas with different conditions cannot be handled uniformly
Solution Approach 1:
The imaging area is divided into multiple regions, each with its own image-capturing conditions. The selection unit segments the task by choosing pixels from specific regions based on the required image-capturing conditions, enabling uniform processing of data from different regions while maintaining region-specific quality optimizations
Solution Approach 2:
Different image-capturing conditions are applied to different areas to optimize local image quality. The selection unit and generation unit then work together to uniformly handle the image data by selecting appropriate pixels from regions with matching conditions, preserving local optimizations while achieving global uniformity
2Device complexity
If pixel selection for interpolation is fixed, then processing is simplified, but image quality cannot be optimized for different image-capturing conditions
Solution Approach 1:
The pixel selection process is made dynamic by having the selection unit adjust its choices based on the image-capturing conditions. This allows the system to optimize image quality for different conditions while maintaining a relatively simple overall processing architecture through the generation unit's interpolation operations

AI summary
An image-capturing device includes: an image sensor that includes an image capturing area where an image of a subject is captured; a setting unit that sets image capturing conditions to be applied to the image-capturing area; a selection unit that selects pixels to be used for interpolation from pixels present in the image-capturing area; and a generation unit that generates an image of the subject captured in the image-capturing area with signals generated through interpolation executed by using signals output from the pixels selected by the selection unit, wherein: the selection unit makes a change in selection of at least some of the pixels to be selected depending upon the image-capturing conditions set by the setting unit.
