Mask Image Positioning in Image Pickup Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image pickup systems require complex coordinate system management for mask positioning, making it difficult for clients to set and manage mask images across multiple cameras with different coordinate systems, leading to complicated processing and inefficient mask placement.
Innovation Solution
An image pickup apparatus with a transmitting unit for designating image pickup direction and a setting unit for determining mask position based on received designations, allowing for the superimposition of mask images within the image pickup range, independent of camera coordinate systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a coordinate system shared by camera and client is used for mask position identification, then the mask processing function can be implemented, but the client needs to replace mask position information with coordinate values in the shared coordinate system and transmit them to the camera, making the processing in the client complicated
Solution Approach 1:
Instead of having the client convert mask positions to camera coordinate system, the invention inverts the approach by having the camera transmit its coordinate system information to the client. The client then uses this information to calculate mask positions directly in the camera's coordinate system, reversing who performs the coordinate transformation and simplifying client processing.
Solution Approach 2:
The invention introduces coordinate system information as an intermediary element between the camera and client. This intermediary data allows the client to accurately determine mask positions in the camera's coordinate system without complex manual conversion, facilitating seamless mask processing across different coordinate systems.
2Adaptability or versatility
If mask position information is designated in a coordinate system shared by multiple cameras, then mask setting can be configured for multiple cameras, but the client needs to designate coordinate position of mask image in accordance with the coordinate system of each camera individually, making processing complicated
Solution Approach 1:
The invention makes the mask position designation process universal across multiple cameras by having each camera transmit its coordinate system information to the client. The client can then use a unified approach to calculate mask positions for any camera using that camera's specific coordinate system information, eliminating the need for individual coordinate system knowledge for each camera.
Solution Approach 2:
Coordinate system information acts as an intermediary that enables universal mask position designation across multiple cameras. By receiving this information from each camera, the client can accurately place masks in any camera's field of view using consistent processing logic, simplifying multi-camera mask configuration.
3Adaptability or versatility
If the camera and client use different coordinate systems, then each camera can maintain its own coordinate system, but the client cannot easily set mask positions across different image pickup directions without complex coordinate transformations
Solution Approach 1:
The invention uses coordinate system information as an intermediary that allows cameras to maintain their independent coordinate systems while enabling the client to perform accurate mask positioning. The client receives coordinate system information from each camera and uses it to calculate appropriate mask positions, eliminating the need for complex manual coordinate transformations.
Solution Approach 2:
Each camera provides its own coordinate system information to the client, enabling self-service for coordinate system management. The client uses this provided information to automatically calculate correct mask positions for each camera's specific coordinate system, eliminating the need for manual coordinate system management and transformations.

AI summary
An image pickup apparatus includes a receiving unit configured to receive a designation of an image pickup direction of an image pickup unit in relation to superimposition of a mask image on an picked-up image; and a setting unit configured to set, when the receiving unit receives the designation of the image pickup direction, a position of superimposition of the mask image in an image pickup range where the image pickup unit can pick up images, on the basis of the designated image pickup direction.
