Image Synthesizing Apparatus for Zoomed Moving Image Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital cameras cannot easily produce a moving image with a zoom effect unless equipped with a moving image pickup mode, and they lack the ability to provide a moving image with the same zoom functionality as optical or electronic zoom during image capture.
Innovation Solution
An image synthesizing apparatus that extracts multiple images of different sizes from a single image, zooms them to a uniform size, and synthesizes them to generate a moving image, allowing for the creation of a zoomed moving image without the need for a dedicated moving image pickup mode or zoom function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional digital cameras are used without a moving image pickup mode, then the device complexity is reduced, but the ability to produce moving images with zoom effects is lost
Solution Approach 1:
The patent divides a single still image into multiple extracted images of different sizes, treating each extracted image as a separate frame in the moving image sequence. This segmentation allows the creation of zoom effects without requiring multiple physical images or complex hardware components.
Solution Approach 2:
The patent creates multiple copies of the original image at different scales (extracted images), then synthesizes these copies into a moving image sequence. This copying approach enables zoom functionality without requiring optical zoom hardware or electronic zoom mechanisms.
2Reliability
If multiple still images are captured to create a moving image, then the moving image quality is improved, but the time required to create the moving image increases
Solution Approach 1:
The patent performs image extraction and synthesis operations in advance, creating the moving image sequence from a single captured image before playback. This preliminary processing allows the moving image to be generated quickly without requiring multiple sequential image captures during the shooting moment.
Solution Approach 2:
The system uses the single captured image itself as the source material for generating the moving image, eliminating the need to capture additional images. The original image serves multiple purposes: as the base image and as the source for all extracted images used in the moving image sequence.
3Manufacturing precision
If extracted images are zoomed up to the same size as the original image, then the image quality is maintained, but the processing time increases
Solution Approach 1:
The patent changes the size parameter of extracted images through zooming operations, scaling them to match the original image dimensions. This parameter transformation allows different-sized extracted images to be synthesized into a uniform moving image sequence while maintaining visual quality.
Data Source
AI summary
Disclosed is an image synthesizing apparatus which extracts plural images of different magnification ratios from a single piece of image data and combines those images to provide a moving image equivalent to a moving image zoomed up in moving image pickup. In record mode, an image acquired by a CCD is subjected to color processing and is then sent to an image memory. At the same time, a through image is displayed on a display section. If it is a zoomed moving image mode, when a shutter is pressed to pick up an image, plural images zoomed up in plural levels are created based on image data stored then in the image memory as an original image. A zoomed moving image equivalent to a zoomed moving image is obtained in moving image pickup.
