Solution Overview

Problem

Existing information display apparatuses, such as those described in PTL 1 and PTL 2, do not allow users to easily view previous or next images immediately while displaying images, as they either superimpose thumbnail images or display last images at screen corners, making it inconvenient to review or reference multiple images.

Innovation Solution

An information display apparatus with a touch detection unit, motionlessness detection unit, and behavior detection unit that allows users to fix a touch position to reduce and continue displaying a kept image, enabling frame advance or backward instructions to show adjacent images, with optional face detection to maintain important image areas and display indicators for kept images.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If thumbnail images of previous and next images are superimposed on the displayed image, then image review capability is provided, but the user cannot view images recorded before the previous image or after the next image immediately

Engineering Contradiction:
Improveimage review capabilityVSAvoidtime to access historical images
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The display screen is divided into multiple independent display areas: a first display area showing the current image, a second display area showing the previous image, and a third display area showing the next image. This segmentation allows users to access images from different time periods simultaneously without superposition, resolving the contradiction between providing image review capability and enabling immediate access to historical images.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If last images are displayed at corner areas of the screen during photographing, then preparation for photographing can be performed, but a desired image recorded before the image recorded before the last image cannot be displayed immediately

Engineering Contradiction:
Improvephotography preparation capabilityVSAvoidtime to access historical images
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The display screen is segmented into multiple functional areas: a first display area for current image display, a second display area for previous image display, and a third display area for next image display. This eliminates the need to place last images at corner areas, allowing immediate access to any historical image while maintaining photography preparation capabilities.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a two-dimensional corner display arrangement to a multi-area distributed display layout. By creating separate display regions for different image types across the screen, the system enables simultaneous access to multiple historical images without time loss, while corner areas can still serve their original purpose for photography preparation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If a touch operation is used to select and view content, then operation simplicity is improved, but it becomes difficult to recognize what the kept information is

Engineering Contradiction:
Improveoperation simplicityVSAvoidrecognition of kept information
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

Different display areas are assigned different qualities and functions: the first display area shows the current image with full detail, the second display area shows the previous image, and the third display area shows the next image. This local differentiation allows users to easily recognize which area contains kept information while maintaining simple touch operations for navigation between areas.

Inventive Principle:
Principle #3Local quality

AI summary

An information display method includes steps of: detecting a touch position of an object on a screen of a display unit; determining whether a plurality of touch positions are detected; detecting a motionless touch position which is motionless for a predetermined time period in the plurality of detected touch positions; detecting a behavior of a touch position other than the motionless touch position among the plurality of detected touch positions; detecting an instruction corresponding to the behavior of the touch position; and controlling, in accordance with the motionless touch position and the detected instruction, the display unit to reduce an display area of a kept image, the image being displayed on the display unit when the motionless touch position is detected, to a predetermined size to continue displaying the reduced kept image, and to display an image other than the reduced kept image.
