Image Processing Apparatus Recording Size Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In digital cameras, the selection of recording sizes can be confusing due to differences in the angle of view caused by varying lenses, leading to inconsistent pixel counts across different recording sizes, particularly when the smallest recording size (S2 size) may not always be the smallest, which can perplex users.
Innovation Solution
An image processing apparatus and method that allows users to select from multiple recording sizes (first, second, and third sizes) based on two modes, where the first mode includes all sizes and the second mode excludes the second size, ensuring pixel count consistency and user clarity by determining pixel reduction ratios and setting thresholds for available sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the S2 size is set as the smallest recording size independent of image sensor pixels, then web material compatibility is improved, but the S2 size may become larger than M size and S1 size when image circle is small, causing user confusion
Solution Approach 1:
The patent applies dynamics by making the available recording size options change based on the shooting mode. In normal shooting mode, all sizes including S2 are available, but in cropped shooting mode, only L size and S2 size are available. This dynamic adjustment of available options based on conditions resolves the contradiction by adapting the system to different shooting scenarios.
Solution Approach 2:
The patent changes the parameter of available recording size options based on the shooting mode. When cropped shooting is detected, the system restricts available sizes to only L and S2, effectively removing M and S1 from the options. This parameter change ensures that S2 remains the smallest selectable size in cropped mode, preventing user confusion while maintaining web material compatibility.
2Object-affected harmful factors
If cropped shooting is used to match image circle size, then peripheral darkness is eliminated, but the number of effective pixels decreases, causing L size, M size, and S1 size to become smaller
Solution Approach 1:
The patent extracts the S2 size option from the dependency on effective pixel count. While L size, M size, and S1 size are calculated based on the reduced effective pixels after cropping, S2 size maintains its fixed pixel dimensions (2400×1600) independent of the cropping operation. This extraction allows the system to eliminate peripheral darkness through cropping while maintaining a consistent smallest size option for web materials.

AI summary
An image processing apparatus comprises a processor capable of setting a first mode of outputting image data corresponding to a first region of an image sensor including a plurality of pixels, and a second mode of outputting image data corresponding to a second region that is smaller than the first region, and selecting one of a plurality of sizes at least including first, second and third sizes as an output size for image data. The second size is based on the first size, and if the first mode is set, the first, second and third sizes are included as choices of size from which the processor selects, and if the second mode is set, the first and third sizes, excluding the second size, are included as the choices of size.
