Image Sensor Live View Display Switching for Parameter Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image sensing apparatuses require users to cancel enlarged live view displays to set photographing parameters like exposure and ISO sensitivity, leading to poor user operability during enlarged image viewing.
Innovation Solution
An image sensing apparatus with a display that switches between enlarged and full-screen views of live images, allowing setting of image sensor parameters without switching to full-screen mode, using a processor to manage these operations based on specific user actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display switches to full screen mode when a setting operation is detected during enlarged display, then the setting operation can be performed, but the enlarged display is interrupted and user operability deteriorates
Solution Approach 1:
The patent applies dynamics by making the display mode adaptive rather than fixed. The display dynamically switches between enlarged display mode and full screen mode based on the type of operation detected. When a setting operation (non-display operation) is detected, the display temporarily switches to full screen mode to enable setting, then returns to enlarged display mode. This dynamic adaptation resolves the contradiction by allowing setting operations without permanently interrupting the enlarged display workflow.
Solution Approach 2:
The patent applies preliminary action by detecting the type of operation in advance and preparing the appropriate display mode accordingly. Before executing a setting operation, the system detects it as a non-display operation and proactively switches to full screen mode, ensuring the setting can be performed without interruption. This preliminary preparation eliminates the need for users to cancel enlarged display first, reducing time loss.
2Ease of operation
If the enlarged display is maintained during setting operations, then user operability improves, but the system cannot properly handle setting inputs
Solution Approach 1:
The patent makes the display mode dynamic based on operation type. When a setting operation is detected, the display switches to full screen mode to provide proper input handling capability, then returns to enlarged display mode after setting is complete. This dynamic switching allows the system to adapt its handling capability to match the current operation requirement while maintaining good user operability throughout.
Solution Approach 2:
The patent applies multi-functionality by making the display serve different functions based on the current operation state. The same display unit provides enlarged view functionality during viewing operations and full screen setting interface functionality during setting operations. This universal approach allows the system to handle different operation types effectively without requiring separate display systems, improving both adaptability and user operability.
3Reliability
If the display remains in enlarged mode during setting operations, then the display continues to show the live view, but setting parameters cannot be properly determined
Solution Approach 1:
The patent applies dynamics by switching the display mode based on the operation being performed. When a setting operation is detected, the display dynamically transitions to full screen mode to ensure reliable setting parameter determination, then returns to enlarged display mode afterward. This dynamic behavior ensures that setting parameters can be properly determined while maintaining good operability throughout the process.
Solution Approach 2:
The patent uses the display mode switch as an intermediary mechanism to bridge between enlarged display mode and setting operation requirements. The full screen mode acts as an intermediary state that enables proper setting parameter determination without permanently leaving the enlarged display workflow. This intermediary approach allows the system to temporarily adopt the necessary display characteristics for reliable setting while maintaining the overall enlarged display context.

AI summary
An image sensing apparatus, comprising: an image sensor to capture an image; a display to display a full screen image and a display controlling unit to switch an image to be displayed by the display between an enlarged image and the full screen image; and a control unit to perform, in accordance with a predetermined operation, a first setting for determining a setting parameter of the image sensor in a first state and a second setting for determining a predetermined range of the live view image in a second state, wherein when the predetermined operation is performed while the display displays the enlarged image, the display controlling unit does not switch the image displayed to the full screen image, and the control unit performs the first setting if the display is in the first state, and performs the second setting if the display is in the second state.
