Tally Lamp Control for Multi-Media Recording State Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording apparatuses cannot accurately distinguish between intended and unintended recording states when recording moving images onto multiple media, leading to confusion for the subject being photographed.
Innovation Solution
A recording apparatus with a control unit that manages a lighting unit to indicate recording states differently for primary and secondary recording media, ensuring the tally lamp status reflects the intended recording state based on user instructions and media selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If recording is performed to multiple recording mediums simultaneously, then recording capacity and backup reliability are improved, but the tally lamp cannot distinguish between intended and unintended recording states
Solution Approach 1:
The patent divides the recording indication into separate components: a first tally lamp for indicating intended recording and a second tally lamp for indicating backup recording. This segmentation allows the system to distinguish between different recording states simultaneously, resolving the contradiction by providing separate information channels for each recording function.
Solution Approach 2:
The patent applies different indication qualities to different recording mediums: the first tally lamp uses one indication pattern (e.g., solid light) for main recording, while the second tally lamp uses another pattern (e.g., blinking light) for backup recording. This local differentiation of indication quality enables clear distinction between intended and unintended recording states.
2Device complexity
If a single tally lamp is used for multiple recording mediums, then device complexity is reduced, but recording state distinction capability deteriorates
Solution Approach 1:
The patent segments the single tally lamp function into multiple independent indication mechanisms - separate tally lamps or distinct indication patterns - to provide clear recording state information. This segmentation increases device complexity minimally while dramatically improving recording state detectability.
Solution Approach 2:
The patent utilizes different light patterns (on/off, solid/blinking) or colors of the tally lamp to indicate different recording states. By encoding recording state information through pattern variations rather than requiring separate physical lamps, the system achieves clear state distinction with moderate complexity increase.

Function Achieved in This Case
The solution allows for clear indication of intended recording states, enhancing user awareness and reducing confusion for the subject being photographed by accurately representing the recording status through distinct lighting states.
Implementation Method 1
a lighting unit; a control unit configured to control the lighting unit
Data Source
AI summary
A imaging apparatus controls a lighting unit such that when the first recording medium is selected, the lighting unit is turned into a state different from a predetermined state in a state where recording into the first recording medium is stopped while recording into the second recording medium, and turned into the predetermined state in accordance with a recording start instruction of the first recording medium during recording into the second recording medium, and when the second recording medium is selected, the lighting unit is turned into the state different from the predetermined state in a state where recording into the second recording medium is stopped while recording into the first recording medium, and turned into the predetermined state in accordance with the recording start instruction of the second recording medium during recording into the first recording medium.
