Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Game machines like pachinko and pachislot machines face significant processing speed reductions when displaying multiple moving pictures with low resolutions due to inefficient decoding performance by general-purpose hardware decoders, which is exacerbated by parallel processing limitations and associated initialization processes.
Innovation Solution
An image data processing method that combines multiple moving pictures at the slice level to create integrated encoded data, allowing a hardware decoder to process them as a single image, thereby reducing the need for repeated initialization and enhancing decoding speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple low-resolution moving pictures are decoded separately by a hardware decoder, then each picture can be decoded with proper initialization, but the decoding processing speed decreases due to repeated initialization and parallel processing limitations
Solution Approach 1:
The patent combines multiple low-resolution moving pictures into a single integrated picture for decoding by the hardware decoder. This merging approach allows the decoder to process multiple pictures in one decoding operation, eliminating repeated initialization overhead and improving processing speed while maintaining decoding accuracy through proper slice-level integration.
Solution Approach 2:
The patent makes the hardware decoder capable of handling multiple picture types simultaneously by integrating multiple low-resolution pictures into a unified decoding stream. This multi-functionality allows the decoder to process different picture resolutions and types through a single standardized interface, improving overall system efficiency.
2Ease of operation
If a hardware decoder processes multiple low-resolution moving pictures as separate entities, then initialization procedures can be properly executed, but the processing efficiency deteriorates due to parallel processing limitations
Solution Approach 1:
Multiple low-resolution moving pictures are merged into a single integrated picture structure that maintains proper decoding initialization while enabling efficient parallel processing. The integration preserves initialization procedures through slice-level organization while improving processing efficiency by reducing the number of separate decoding operations required.
Solution Approach 2:
The patent segments the integrated picture into multiple slices, each corresponding to a original low-resolution picture. This segmentation allows the hardware decoder to process the integrated picture efficiently using parallel processing capabilities while maintaining the structural integrity and initialization requirements of individual pictures through slice-level organization.
3Manufacturing precision
If the hardware decoder is configured to handle multiple low-resolution pictures individually, then proper decoding control is maintained, but the initialization overhead increases and slows down processing
Solution Approach 1:
The patent merges multiple low-resolution pictures into a single integrated picture that is processed by the hardware decoder in one decoding operation. This approach maintains precise decoding control through slice-level organization while eliminating repeated initialization overhead, as the decoder performs initialization only once for the integrated picture rather than separately for each individual picture.

AI summary
Provided is an image data processing method for preventing decrease of a decoding processing capability of an image processing device even if the image processing device is included in a game machine on which many moving pictures having low resolutions are displayed. First, decoding processing is designed (step S1). For example, it is designed in such a manner that a moving picture X is singly processed and that a moving picture Y and a moving picture Z having low vertical resolutions can be combined together to be subjected to decoding processing. Subsequently, each of the moving picture X, the moving picture Y, and the moving picture Z is encoded (step S2). Next, encoded data of the moving picture X is singly decoded, and the moving picture X is restored and displayed on a display unit of the image processing device at a predetermined timing. Meanwhile, respective pieces of encoded data of the moving picture Y and the moving picture Z are combined together and are decoded depending on respective display timings, and the moving picture X and the moving picture Y are restored and further separated from each other to be displayed on the display unit at the respective timings (step S3).
