Image Pickup Apparatus Scene-Aware Bracket Shooting Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image pickup apparatuses require cumbersome settings and advanced knowledge to perform bracket shooting effectively, making it difficult for users to select appropriate settings for a specific shooting scene.
Innovation Solution
An image pickup apparatus with a shooting scene determining unit, a selecting unit, and an image processor that automatically selects and performs suitable bracket shooting based on the determined scene, allowing for appropriate parameter adjustments such as exposure, focus, and white balance without requiring advanced user input.

Engineering Contradiction Analysis
1Reliability
If bracket shooting is performed with multiple parameter settings, then the quality and variety of captured images are improved, but the operation complexity and user burden increase
Solution Approach 1:
The image pickup apparatus automatically determines the shooting scene type and selects appropriate bracket shooting parameters without requiring manual user input. The system analyzes the captured image data, identifies the scene category (e.g., landscape, portrait, night scene), and autonomously configures multiple shooting parameters including exposure compensation values, focus positions, and white balance settings, thereby eliminating the need for users to manually set complex bracket shooting parameters while still achieving high-quality results
Solution Approach 2:
The system dynamically adjusts shooting parameters based on the determined scene type. Different scene types trigger different parameter configurations: for example, landscape scenes may use exposure bracketing with values of -1, 0, +1 EV, while portrait scenes may use focus bracketing with different focus distances. This parameter adaptation allows the system to optimize image quality for each specific scene without requiring users to understand or configure the underlying parameter settings
2Measurement precision
If manual parameter settings are required for bracket shooting, then the precision of parameter selection is improved, but the time required for setup and operation increases
Solution Approach 1:
The system pre-configures multiple sets of bracket shooting parameters corresponding to different scene types before actual shooting begins. When a scene is captured, the system quickly identifies the scene type and retrieves the pre-prepared parameter set, eliminating the need for time-consuming manual parameter adjustment. The pre-configured parameter sets include optimized exposure compensation values, focus positions, and white balance settings for various scene categories, enabling rapid deployment
Solution Approach 2:
The system analyzes the captured image data in real-time to determine the shooting scene type and automatically adjusts parameters based on this feedback. The image processing unit evaluates luminance distribution, color temperature, and subject characteristics to identify the scene category, then immediately applies the appropriate bracket shooting parameters. This closed-loop feedback mechanism ensures accurate parameter selection while minimizing setup time, as the system continuously adapts to the actual shooting conditions

AI summary
An image pickup apparatus includes a shooting scene determining unit configured to determine a shooting scene, a selecting unit configured to select a bracket shooting from a plurality of bracket shootings which alter parameters in different ways from each other, based on the shooting scene determined by the shooting scene determining unit, and an image pickup unit configured to perform the bracket shooting selected by the selecting unit, and the selecting unit selects one type of bracket shooting even when the shooting scene determined by the shooting scene determining unit is suitable for at least two types of bracket shootings in the plurality of bracket shootings.
