Dual Display Image Signal Processing with Gyro-Based Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital photographing devices with dual displays currently require a separate selection operation to display different images on each display unit, which is inconvenient and does not allow for direct high-quality image display to a photographed person.
Innovation Solution
A digital image signal processing apparatus with multiple display units and a control method that allows different images to be displayed on each unit based on user selection, using a digital signal processing unit, display memory, and address units to manage and read image data for independent display on first and second display units, optionally with a gyro sensor for orientation-based selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the same image is displayed on both display units, then the device structure is simple, but the photographer cannot selectively display different desired images to the photographed person
Solution Approach 1:
The patent divides the display system into two independent display units (first display unit and second display unit), each capable of displaying different images. The image data is segmented into first image data and second image data, allowing independent control and display of different images on each unit without requiring complex coordination between them.
Solution Approach 2:
The patent stores multiple pieces of image data in advance in the display memory, including first image data and second image data that are prepared beforehand. This preliminary storage allows the system to quickly switch between different images without requiring complex real-time processing or selection operations during display.
2Ease of operation
If a separate selection operation is required to display different images, then the control logic is simple, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The patent employs a sensor unit (such as a gyro sensor) that automatically detects the user's selection intent based on device orientation or movement. This self-service mechanism eliminates the need for manual selection operations, as the system automatically determines which image to display based on sensor input, thereby saving time and improving ease of operation.
Solution Approach 2:
The patent replaces manual mechanical selection operations with sensor-based automatic detection. Instead of requiring the user to physically interact with buttons or menus to select images, the system uses sensor units to detect orientation or movement and automatically switches between images, substituting mechanical interaction with automated sensing.
3Adaptability or versatility
If multiple pieces of image data are stored in display memory, then different images can be displayed, but the memory requirements and data management complexity increase
Solution Approach 1:
The patent segments image data into distinct categories (first image data and second image data) and assigns them to different display units. This segmentation simplifies data management by creating clear boundaries between data sets, making it easier to track and control which data is displayed on which unit without requiring complex cross-referencing or coordination.
4Adaptability or versatility
If different images are displayed on display units, then the photographer can select desired images for the photographed person, but the system complexity increases
Solution Approach 1:
The patent divides the display system into two independent display units with separate address units and data streams. This segmentation allows each unit to operate independently, simplifying the overall control logic despite the increased functionality. Each display unit has its own address unit that can independently read and display different image data without interfering with the other unit.
Solution Approach 2:
The patent prepares and stores multiple pieces of image data in advance in the display memory, including first image data and second image data. This preliminary preparation eliminates the need for complex real-time image processing or selection operations, as the system only needs to retrieve pre-prepared data based on simple selection criteria.

AI summary
A digital image signal processing apparatus includes a digital signal processing unit, a plurality of display units, and a display driving unit. The digital signal processing unit provides a plurality of pieces of image data that respectively form a plurality of images. The plurality of display units display images corresponding respectively to the plurality of pieces of the image data. The display driving unit includes a display memory that records the plurality of pieces of image data, a recording address unit that controls the plurality of pieces of image data to be recorded in the display memory, and a plurality of display address units that respectively read the recorded pieces of image data and provide the recorded pieces of image data respectively to the display units. Accordingly, a photographer may directly display a desired image to a photographed person as a high-quality filtered image without a separate selection operation.
