Coordinate Conversion for Dual-Optical Camera Remote Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to adequately address the issue of displaying and processing live view images from digital cameras equipped with dual optical systems, leading to incorrect positional relationships between images, which complicates remote camera control.
Innovation Solution
A processing apparatus that includes a communication unit to communicate with an imaging apparatus, a control unit to display the third image on a display unit, and a setting unit to set and convert the position of a target region for image processing based on the display format, ensuring accurate image processing and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an image captured by a digital camera with dual optical systems is displayed using conventional single-lens display methods, then the display process is simple, but the positional relationship between the two images becomes incorrect
Solution Approach 1:
The patent applies preliminary action by performing coordinate conversion of the target region position before transmitting control commands to the camera. The external terminal converts the position coordinates from the display coordinate system to the camera sensor coordinate system in advance, ensuring that the positional relationship is correctly maintained when the images are captured and displayed
Solution Approach 2:
The patent uses an intermediary approach by introducing a coordinate conversion process as a mediator between the display system and the camera control system. The control unit acts as an intermediary that translates positions between the two different coordinate systems, allowing the simple display method to work correctly with dual optical systems
2Productivity
If image processing is performed on a dual optical system image without position conversion, then the processing is straightforward, but the processed region does not correspond to the intended area in the displayed image
Solution Approach 1:
The patent applies preliminary action by pre-converting the target region position coordinates before initiating image processing. The external terminal calculates and converts the position coordinates in advance based on the display format and transmits the converted coordinates to the camera, ensuring that the subsequent image processing operates on the correct region without losing target region correspondence
3Ease of operation
If the camera control is performed without considering the dual optical system parallax, then the control operation is simple, but the captured images do not match the user's intended composition
Solution Approach 1:
The patent uses an intermediary approach by introducing a coordinate conversion process as a mediator between the display system and the camera control system. The control unit acts as an intermediary that translates positions between the two different coordinate systems, allowing the simple display method to work correctly with dual optical systems

AI summary
An information processing apparatus includes a communication unit configured to communicate with a camera configured to capture a third image which is one image in which left and right images are arranged, and a control unit configured to display the third image on a display unit and set a position of an enlarged range to which enlargement processing is to be applied by the camera in the third image displayed on the display unit, and the control unit converts the set position of the enlarged range based on a display format in which the third image is displayed on the display unit, and outputs an instruction to the camera.
