Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional game media dispensers in pachinko and pachi-slot game machines face challenges in identifying player faces in dimly lit environments, leading to short lifespans of auxiliary light devices and increased costs due to constant high brightness illumination, and there is a need for a system that can conduct personal authentication in overseas casinos with even lower lighting settings.
Innovation Solution
A game peripheral device equipped with an imaging device, a lighting device, a brightness determination signal detection device, and a lighting controller that adjusts the emission brightness based on detected signals, such as operator operations or game events, to optimize light usage and extend the life of the light source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the auxiliary light device keeps illuminating the player's face with infrared light at fixed brightness during the entire opening hours, then the face image can be clearly identified, but the auxiliary light device has a short life and frequent replacements are required
Solution Approach 1:
The patent applies periodic action by controlling the infrared LED to illuminate only during specific periods when face image capture is required (such as during player authentication or game events), rather than continuous illumination. This temporal segmentation allows the light device to rest during non-critical periods, extending its operational lifespan while maintaining sufficient illumination when needed for accurate face identification.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting the illumination brightness and duration based on operational requirements. The system varies the infrared LED's emission parameters (brightness level, illumination duration) according to the specific task at hand, using higher brightness only when face capture is needed and reducing or eliminating illumination during normal gameplay, thereby balancing identification accuracy with device longevity.
2Illumination intensity
If the auxiliary light device illuminates at high brightness to identify face images in dim game halls, then face identification is possible, but the light source lifespan is reduced and operational costs increase
Solution Approach 1:
The system employs periodic illumination rather than continuous high-brightness lighting. The infrared LED is activated in periodic bursts synchronized with game events or authentication moments, providing intense illumination only when necessary for face capture, while remaining dormant during extended periods, thus reducing cumulative light source consumption and extending operational life.
Solution Approach 2:
The illumination system is made dynamic by adjusting brightness levels in real-time based on operational context. The system transitions between different illumination states (high brightness for capture, low or zero brightness for normal operation) rather than maintaining a fixed high brightness level, optimizing the balance between illumination intensity and light source preservation.
3Adaptability or versatility
If the lighting is set dim to increase presentation effects in casinos, then the atmosphere is improved, but face identification becomes difficult
Solution Approach 1:
The patent introduces an intermediary infrared illumination system that bridges the gap between dim ambient lighting and sufficient face visibility. The infrared LED acts as a mediator by providing targeted illumination specifically for face capture without affecting the overall dim ambiance of the casino, allowing presentation effects to be maintained while ensuring adequate lighting for authentication when required.
Solution Approach 2:
The system applies local quality by providing illumination only in the specific local area where face capture is needed, rather than uniformly brightening the entire environment. The infrared LED focuses light on the player's face locally, leaving the rest of the casino dimly lit to preserve the desired atmosphere and presentation effects.

AI summary
The present application provides a game peripheral device including an auxiliary light device available for long-time use. An emission brightness determination device for determining emission brightness of illumination light determines the emission brightness at first emission brightness under the condition where a brightness determination signal has been detected and determines the emission brightness at second emission brightness under the condition where an imaging device has taken an image of a player's face.
