Touch Panel Display Enlarging Input Region for Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in inputting images on a small touch panel display screen while viewing an entire background image, as it is hard to comprehend the position, size, and direction of the input image relative to the background.
Innovation Solution
A printing apparatus and method that displays an enlarged portion of the background image including the input region on the screen, allowing users to input images easily by designating the input region on a larger displayed background image, and then captures and prints the composite image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the entire background image is displayed on a small touch panel screen, then the user can see the overall layout, but it becomes difficult to accurately input images at specific positions due to the small screen size
Solution Approach 1:
The display screen is segmented into multiple regions: a full background image display region and an enlarged input region. The system divides the display area to show both the overall context (full background image) and the detailed input area (enlarged portion) simultaneously, allowing users to see both the big picture and precise positioning information.
Solution Approach 2:
The system adds a spatial dimension to the display by showing an enlarged view of the input region alongside or overlaid on the full background image. This creates a multi-scale display where users can perceive both the overall layout and the detailed input area in the same visual field, effectively utilizing the limited screen real estate through dimensional arrangement.
2Measurement precision
If an enlarged portion of the background image is displayed to facilitate image input, then position recognition improves, but the user loses overview of the entire background image
Solution Approach 1:
The display is segmented to show multiple views simultaneously - the full background image and the enlarged input region are displayed in separate areas of the screen. This segmentation allows users to maintain awareness of the overall layout while also having access to the detailed enlarged view for precise input.
Solution Approach 2:
The system merges multiple display views (full background image view and enlarged input region view) into a single composite display. Both views are combined on the same screen, allowing users to see the complete background image while also viewing the enlarged portion needed for accurate input positioning.
3Ease of operation
If the display screen is made larger to allow direct drawing of input images, then ease of operation improves, but the machine size increases
Solution Approach 1:
The system creates a virtual copy or representation of the input region by displaying an enlarged view of that specific area on the touch panel. This virtual enlargement allows users to draw and input images with the precision of a large screen while maintaining the compact physical size of the actual device.
Solution Approach 2:
The system changes the display parameter (magnification level) of specific regions dynamically. By adjusting the scale of the displayed image portion and selectively enlarging only the relevant input area, the system provides the operational ease of a large screen without physically increasing the device size.

AI summary
A printing apparatus which prints a composite image formed of a background image and an input image on a recording medium includes: a display; a display image data generating section which generates data of a display image to be displayed on the display; a display controller which controls the display; an input region determining mechanism which determines at least one input region in which the input image is to be inputted on the background image displayed on the display; an image capturing mechanism which captures the input image inputted via the display; a composite image data generating section which generates data of the composite image from data of the background image and the input image captured by the image capturing mechanism; and a printing mechanism which prints the composite image on the recording medium based on the data of the composite image generated by the composite image data generating section.
