Solution Overview

Problem

Existing game systems struggle with appropriate image display when capturing human body parts, particularly faces, due to variations in camera positioning and image quality, leading to inconsistent and potentially poor-quality image rendering.

Innovation Solution

A system and method that generates and transmits image data and state data based on the captured image, allowing reception terminals to determine and adjust the displayed image quality and content, including face detection, enlargement, and blur modes, ensuring consistent and high-quality image rendering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the captured image is transmitted directly without processing, then the image data transmission is simple, but the image quality varies significantly when the camera position changes

Engineering Contradiction:
Improveimage quality consistencyVSAvoidimage processing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The transmission terminal performs preliminary image processing before transmission by detecting human body parts in the captured image, extracting only the relevant portions containing human body parts, and generating processed image data. This preliminary action ensures that the received image always contains human body parts at appropriate positions regardless of camera position, while avoiding the need for complex processing at the reception terminal

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The transmission terminal extracts only the necessary portions of the captured image that contain human body parts, separating them from the rest of the image. This extraction process removes unnecessary background and other elements, transmitting only the relevant image data containing human body parts to the reception terminal, thereby ensuring consistent image quality

Inventive Principle:
Principle #2Taking out (Extraction)

2Loss of information

If the entire captured image is transmitted, then all image information is preserved, but the data transmission volume increases and processing becomes more complex

Engineering Contradiction:
Improveimage information completenessVSAvoiddata transmission volume
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The transmission terminal extracts only the necessary portions of the captured image that contain human body parts, separating them from the rest of the image. This extraction process removes unnecessary background and other elements, transmitting only the relevant image data containing human body parts to the reception terminal, thereby ensuring consistent image quality

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of transmitting the entire captured image, the system transmits only the partial image data that contains human body parts. This partial action approach transmits less data than the full image while preserving all necessary information about human body parts, achieving a balance between information completeness and data volume

Inventive Principle:
Principle #16Partial or excessive action

3Ease of operation

If no image processing is performed at the transmission terminal, then the processing load is low, but the reception terminal cannot adapt the image display to different camera positions

Engineering Contradiction:
Improveimage display adaptabilityVSAvoidprocessing load
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The transmission terminal performs preliminary image processing before transmission by detecting human body parts in the captured image, extracting only the relevant portions containing human body parts, and generating processed image data. This preliminary action ensures that the received image always contains human body parts at appropriate positions regardless of camera position, while avoiding the need for complex processing at the reception terminal

Inventive Principle:
Principle #10Preliminary action

AI summary

An information processing method in a system including at least one transmission terminal and at least one reception terminal is provided. The information processing method includes generating, at the transmission terminal, first image data. The generating the first image data includes generating, when an image captured by a camera includes a part of a human body, an image of an area which is a partial area of the captured image and includes the part of the human body, as the first image data. The information processing method includes transmitting, at the transmission terminal, the first image data, transmitting, at the transmission terminal, state data based on a state of capturing the human body in the captured image, receiving, at the reception terminal, the first image data and the state data, and generating, at the reception terminal, an image to be shown on a display based on the state data, the generated image including an image based on the first image data or an image based on second image data in place of the first image data.
