Imaging Apparatus Object Detection Feedback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In imaging scenarios involving multiple cameras, such as a soccer game, it is challenging for photographers to determine if a remote imaging camera is capturing the desired object due to difficulties in recognizing the imaging status, leading to unnecessary image capture and confusion between obstacles blocking the view and autofocus failures.
Innovation Solution
An imaging apparatus with an image sensor, operation member, communicator, and processors that acquire images, detect objects, and select a main object, allowing for communication of instructions between cameras to ensure accurate object capture, including features like phase difference autofocus and object synchronization information transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual focus adjustment is performed by the photographer, then the photographer can control the focus of the remote imaging camera, but the photographer cannot immediately recognize and correct the imaging status of the remote imaging camera while operating the handheld camera
Solution Approach 1:
The patent implements a feedback mechanism where the handheld imaging camera transmits captured images and detection results to the remote imaging camera. This allows the photographer to immediately see what the remote camera captured and correct focus issues without manual intervention, resolving the contradiction between ease of operation and information loss.
Solution Approach 2:
The patent introduces an intermediary communication system between the handheld and remote imaging cameras. The handheld camera acts as a mediator by capturing images and transmitting them to the remote camera, enabling the photographer to monitor and correct imaging status without directly operating the remote camera.
2Productivity
If the photographer operates the handheld camera without seeing the remote camera's imaging status, then the photographer can focus on capturing images, but a large number of unnecessary images are captured by the remote imaging camera
Solution Approach 1:
The patent uses feedback from the handheld camera to control the remote camera's imaging operations. The remote camera receives images from the handheld camera and uses this information to determine whether to capture images itself, thereby avoiding unnecessary captures and improving overall productivity.
Solution Approach 2:
The patent implements preliminary action by having the handheld camera capture and transmit images before the remote camera operates. This allows the system to pre-determine the imaging status and avoid unnecessary captures by the remote camera, reducing waste of resources.
3Loss of information
If the system uses position and direction information of cameras to determine object capture, then the system can identify when images of desired objects are being captured, but it cannot distinguish between obstacles blocking the view and autofocus failures
Solution Approach 1:
The patent uses the handheld camera as an intermediary to obtain direct visual information about the scene. By transmitting captured images from the handheld camera to the remote camera, the system can accurately determine whether the desired object is visible and being captured, distinguishing between obstacles and focus issues that position-based methods cannot resolve.
Solution Approach 2:
The patent uses the handheld camera to create a copy of the scene's visual information. This copy is then transmitted to the remote camera, allowing the system to indirectly observe the scene and make accurate determinations about object capture status without relying on imprecise position and direction data.

AI summary
An apparatus includes an image sensor, an operation member configured to receive an instruction, a communicator configured to communicate with another apparatus, and one or more processors that execute a program stored in a memory to function as an acquisition unit configured to acquire an image, a detection unit configured to detect objects from the image, and a selection unit configured to select at least one of the objects as a main object, wherein, in a case where the selected main object is detected in the another apparatus, the communicator also transmits the instruction issued to the operation member to the another apparatus.
