Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing pan/tilt camera operation methods are inefficient, requiring multiple touch centering functions to operate the mechanism outside the preview image range, leading to time-consuming and labor-intensive operations.

Innovation Solution

A touch panel interface with designated regions for touch centering, pan angle rotation, and tilt angle rotation instructions, allowing for single-touch operation of the pan/tilt mechanism at desired angles, including intermediate angles and adjustments based on zoom values and touch history.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the touch centering function is used repeatedly to operate the pan/tilt mechanism outside the preview image range, then the imaging unit can be positioned at desired locations, but the operation becomes time-consuming and labor-intensive

Engineering Contradiction:

Improveoperability of pan/tilt mechanismVSAvoidoperation time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The touch panel is divided into multiple functional regions: a central touch centering detection region and surrounding predetermined angle rotation instruction regions. Each region corresponds to specific pan/tilt operations, allowing users to directly touch the desired region to achieve the corresponding operation, eliminating the need for repeated touch centering operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Predetermined pan angle and tilt angle rotation instruction regions are pre-defined on the touch panel around the central detection region. These regions are prepared in advance with specific angular values, enabling users to perform rapid positioning by simply touching the appropriate region without needing to repeatedly execute touch centering operations.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the touch panel is divided into multiple functional regions for different operations, then operation efficiency improves, but the risk of erroneous inputs increases

Engineering Contradiction:

Improveoperation efficiencyVSAvoidinput accuracy

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

Different regions of the touch panel are assigned different functional qualities: the central region handles touch centering operations while surrounding regions handle predetermined angle rotations. This local differentiation allows efficient operation while reducing errors by ensuring each touch location corresponds to a specific, intended function.

AI summary

Provided are an imaging device operation device, an operation method, and a program that can simply and rapidly operate a pan/tilt mechanism such that an imaging unit is located at a desired position. A pan/tilt operation device includes a touch panel in which a touch centering detection region is set, predetermined pan angle rotation instruction regions are set on the left and right sides of the touch centering detection region, and predetermined tilt angle rotation instruction regions are set on the upper and lower sides of the touch centering detection region, a touch centering instruction unit, a predetermined pan angle rotation instruction unit that outputs an instruction to pan a pan/tilt mechanism at a predetermined pan angle, and a predetermined tilt angle rotation instruction unit that outputs an instruction to tilt the pan/tilt mechanism at a predetermined tilt angle.
