Gesture-Controlled Camera Printing to Prevent Instant Film Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital cameras with printers face the issue of wasting print media due to the inability to timely stop printing failed images during self-imaging, especially when the user moves to check the preview display for success or failure, and the cost-effectiveness of specialized remote controllers for print stop instructions is not realistic.
Innovation Solution
A control device for a digital camera with a printer that recognizes combined imaging and print instructions through gestures or voices by the subject, allowing for timely imaging and printing, and includes features to prevent wastage by stopping printing if the subject indicates during a predetermined standby period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the digital camera with printer automatically prints captured images without waiting for print instruction, then the captured image can be instantly printed on the instant film, but failed images are also printed causing waste of print medium
Solution Approach 1:
The system performs preliminary actions by displaying the captured image on the display unit before printing, and recognizes gestures during a predetermined period to determine whether to print. This allows the user to review the image and indicate success or failure before the printing process begins, preventing waste of print medium while maintaining quick printing capability.
2Loss of substance
If an operation member is provided for print stop instruction during preview display, then printing of failed images can be prevented, but the person to be imaged cannot make print stop instruction in time during self-imaging
Solution Approach 1:
The system sets a predetermined period during which gesture recognition results determine whether to print. This preliminary recognition phase occurs before the printing process starts, allowing sufficient time for the person to be imaged to make the gesture indicating print stop instruction, thus preventing both medium waste and time loss.
Solution Approach 2:
The system replaces the mechanical operation member with a gesture recognition system using imaging means. This allows the person to be imaged to issue print stop instructions through natural gestures without needing to physically reach or operate buttons on the camera, enabling timely instructions during self-imaging.
3Loss of substance
If a remote controller is provided for print stop instruction, then printing of failed images can be prevented, but the cost increases due to requiring specialized remote controller and receiving function
Solution Approach 1:
The imaging means serves multiple functions: it captures images for printing, displays preview images, and recognizes gestures for both imaging instructions and print stop instructions. This multi-functionality eliminates the need for separate remote controllers or specialized receiving functions, reducing device complexity and cost while preventing print medium waste.
Solution Approach 2:
The digital camera with printer uses its own imaging means to recognize gestures for print stop instructions, making the system self-sufficient. It does not require external remote controllers or additional specialized components, thereby reducing overall system complexity and cost while maintaining the ability to prevent printing of failed images.

AI summary
The processor recognizes a first act for an imaging and print instruction that combines an imaging instruction and an instruction to print an image, the first act being performed by a person to be imaged who is included in a subject and within an imaging range of a camera unit, causes the camera unit to perform an imaging operation of outputting an image required to be printed in a case where the first act is recognized, recognizes a second act for an instruction to stop printing the image required to be printed, and causes a printer unit to print the image required to be printed in a case where the second act is not recognized during a predetermined print standby period and instructs the printer unit to stop printing the image required to be printed in a case where the second act is recognized during the print standby period.
