Modular Image Signal Processing Apparatus with Detachable Function Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-quality image signal processing apparatuses, such as digital TVs, often lack the flexibility to accommodate diverse user needs for additional functions, as they are built-in and not customizable.
Innovation Solution
A modular image signal processing system that allows users to selectively attach and control additional modules via a connector interface, enabling the output of image and voice signals without the need for a separate control program or conversion unit, using a transceiver, signal decoder, image processor, display, power supply, and controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional functions are built-in to the image signal processing apparatus, then the apparatus can provide multiple functions, but the device complexity increases and cannot be customized according to user needs
Solution Approach 1:
The patent divides the image signal processing apparatus into a main body and separate functional modules. Each module (e.g., DVD player module, music player module, game player module) is an independent unit that can be selectively attached to or detached from the main body, allowing users to customize functions without increasing overall device complexity.
Solution Approach 2:
The main body is designed with a universal interface structure that can accommodate multiple types of functional modules. The standardized connector and controller enable the same main body to work with different modules (DVD, music, game, etc.), providing multi-functionality without requiring separate devices for each function.
2Adaptability or versatility
If separate control programs or converting units are required for each module, then module compatibility is achieved, but the ease of operation decreases
Solution Approach 1:
Each functional module contains its own controller and driver programs that are automatically recognized and loaded when the module is attached to the main body. The system self-configures by detecting the module type through the interface and automatically loading the appropriate control program, eliminating the need for manual installation or separate control programs from the user side.
Solution Approach 2:
The controller in the main body acts as an intermediary between the user and the functional modules. It manages communication with attached modules, automatically selecting and executing appropriate control programs based on module detection, so users simply need to attach modules without dealing with complex control program configurations.

AI summary
Provided are an image signal processing apparatus and a controlling method thereof. The image signal processing apparatus includes a signal decoder, an image signal processor, a display, a controller, a memory, and a power interface. The signal decoder decodes input signals, and the image signal processor processes signals decoded by the signal decoder so that they are outputable. The display outputs the signals processed by the image signal processor, and the controller allows a list of modules recognized by the connector to be displayed, and controls driving of the module selected by a user. The memory stores a program transmitted from the selected module, and the power interface supplies power to the module.
