Image Pickup Device Object Selection via Directional Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image pickup devices require multiple operation components and modes to select and change objects in moving images, making them cumbersome and prone to increased device size, especially when objects are moving and changing places.
Innovation Solution
An image pickup device with a detecting unit, storing unit, operation accepting unit, counting unit, and cancelling unit that allows for selecting and changing a single object using a single operation component, facilitating operations and preventing device size increase by comparing operation counts with detected object numbers.

Engineering Contradiction Analysis
1Ease of operation
If a directional operation component is assigned to a different function at regular image capturing time to select the object, then the function of the directional operation component is changed to select the object, but mode specifically designed to select the object should be prepared which increases the number of operations
Solution Approach 1:
The directional operation component is designed to perform multiple functions: it serves as a general directional control during regular image capturing and automatically switches to object selection mode when multiple objects are detected. This multi-functionality eliminates the need for separate selection modes and reduces the number of operations required.
Solution Approach 2:
The function of the directional operation component dynamically changes based on the detection result. When multiple objects are detected, the component automatically switches to object selection function without requiring manual mode switching, making the system adaptive to the current situation and reducing operational complexity.
2Ease of operation
If the component specifically designed to select the object is prepared, then the object selection function is provided, but the main body of the device is increased in size
Solution Approach 1:
Instead of adding a dedicated object selection component, the patent reuses the existing directional operation component for object selection when multiple objects are detected. This approach provides the object selection function without increasing device size, as no additional hardware components are required.
Solution Approach 2:
The directional operation component serves itself by automatically switching to object selection mode when multiple objects are detected, eliminating the need for separate dedicated components. The existing component adapts its function based on the situation, providing object selection capability without additional hardware.
3Ease of operation
If a single operation component is used to change object at still image reproducing time, then the object change operation is simplified, but it has been difficult to change the object at the image capturing time and/or the moving image reproducing time when objects are always moving and changing places
Solution Approach 1:
The system dynamically adapts the object selection behavior based on the type of image data. For still images, it uses sequential selection. For moving images with moving objects, it automatically switches to a mode that tracks and selects objects based on their current positions, making the system versatile across different scenarios.
Solution Approach 2:
The system performs preliminary detection of multiple objects before the selection operation. When multiple objects are detected in advance, the system prepares the selection interface and automatically switches the directional component to selection mode, enabling smooth object change operations even when objects are moving.

AI summary
If a subject change button of a device is pressed after a face image is detected from moving image data and the number of identified face images is counted, the value of the operation count becomes +1 so that a single face image can be selected. Then, a face image for selection is changed in sequence at the press of the subject change button. If the operation count number exceeds the identified face number of the time, it is determined that a round of the face selection is completed, so that the counted operation number is cleared, the face selection is cancelled, and the device is put on standby.
