Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing electronic devices struggle with performing specific shooting processes, such as AF and AE, in regions of an image divided by aspect markers that the user does not desire, leading to inefficient image capturing, particularly when different aspect ratios are required for different social media platforms.

Innovation Solution

An electronic device capable of switching between modes to enable or disable specific shooting processes like AF and AE in designated image regions, allowing users to customize processing based on their preferences and image type.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the same division setting is used for both still-image mode and moving-image mode, then the display consistency is improved, but the flexibility to perform particular processing in desired regions is worsened

Engineering Contradiction:

Improvedisplay consistencyVSAvoidprocessing flexibility

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by making the division setting changeable according to shooting mode. The system transitions from a static, fixed division setting to a dynamic one where the division setting can be adjusted based on whether still-image mode or moving-image mode is active, allowing optimal configuration for each mode while maintaining display consistency within each mode.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the division setting parameter according to the shooting mode. By switching between different division settings (first division setting for still-image mode, second division setting for moving-image mode), the system adapts the image processing parameters to match the requirements of each mode, enabling flexible control over where particular processing is performed.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If particular processing is restricted to specific regions in still-image mode, then the shooting efficiency is improved, but the device complexity increases

Engineering Contradiction:

Improveshooting efficiencyVSAvoidcontrol complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the image into multiple regions using division lines, and applies different processing rules to different segments. By dividing the image area and assigning specific processing behaviors to specific segments (e.g., performing particular processing only in certain regions), the system improves shooting efficiency by focusing resources on relevant areas while maintaining manageable complexity through clear regional boundaries.

Inventive Principle:

Principle #1Segmentation

AI summary

An electronic device includes a display control unit that performs control to display, on a display unit, a first assisting line that divides an image into at least a first region and a second region, so as to be superimposed on the image, and a control unit that performs control such that, in a first mode for shooting a first type of image, particular processing relating to shooting is inexecutable in the first region, and the particular processing is executable in the second region, and performs control such that, in a second mode for shooting a second type of image that is different from the first type of image, the particular processing is executable in a region including the first region and the second region.
