Image Pickup Apparatus Crop Area Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In digital cameras, it is difficult to recognize the crop area when grid lines extend beyond it, making it challenging to accurately display and utilize the crop area, especially before shooting.
Innovation Solution
The image pickup apparatus controls a display device to illuminate only the assist lines within the crop area, ensuring both the crop area and assist lines are clearly displayed by selectively illuminating segments for the assist lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If grid lines are displayed to assist composition, then composition guidance is improved, but the crop area becomes difficult to recognize when grid lines extend beyond it
Solution Approach 1:
The display is segmented into multiple regions: crop area display units that show the crop area boundary and grid line display units that show grid lines. By controlling which segments are illuminated based on the crop area settings, the patent enables both crop area and grid lines to be clearly displayed without confusion.
Solution Approach 2:
Different display regions are assigned different functions: the crop area display units specifically indicate the crop area boundary, while grid line display units provide composition guidance. This local differentiation ensures that each display element serves its intended purpose without interfering with others.
2Ease of operation
If the entire grid is displayed for composition assistance, then composition guidance is improved, but visual clarity of the crop area boundary deteriorates
Solution Approach 1:
The display system dynamically adjusts which segments are illuminated based on the crop area settings. When a crop area is set, the control unit selectively illuminates only the relevant grid line segments within the crop area, rather than displaying the entire grid statically. This dynamic adaptation maintains both composition guidance and boundary clarity.
Solution Approach 2:
Instead of displaying the complete grid (excessive action), the patent displays only the necessary portion of the grid that falls within the crop area (partial action). This selective display provides sufficient composition guidance while preventing the crop area boundary from being obscured.
3Ease of operation
If assist lines are displayed beyond the crop area, then composition guidance is improved, but the crop area boundary becomes indistinct
Solution Approach 1:
The display is divided into crop area display units and grid line display units with distinct control. The control unit selectively activates only those grid line segments that fall within the crop area boundaries, preventing assist lines from extending beyond the crop area and maintaining precise boundary definition.
Solution Approach 2:
Different display regions serve different functions: grid line segments within the crop area provide composition guidance, while the crop area boundary itself provides precise measurement reference. By controlling grid lines to remain within the crop area, both functions are preserved without interference.

AI summary
An image pickup apparatus is capable of displaying a crop area and assist lines in a finder. The assist lines are displayed by one or more segments. A processor performs control to illuminate and to stop illuminating the segments, to display the assist lines only within the crop area while displaying the crop area, when displaying both of the crop area and the assist lines. Further, the processor performs control to illuminate and to stop illuminating the segments, not to display a line in proximity to the crop area among the assist lines.
