Thumbnail Orientation Reconstruction in Digital Camera Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital cameras face difficulties in displaying images taken in different shooting postures, particularly as vertically framed images are displayed smaller than horizontally framed images when shown as thumbnails, leading to reduced visibility and discomfort for users.
Innovation Solution
An imaging device with a posture detector and image display controller that reconstructs and displays images according to their original shooting posture, ensuring consistent size and orientation of both horizontally and vertically framed images, even when displayed as thumbnails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If vertically framed images are displayed as thumbnails without reconstruction, then the display process is simple, but the visibility and image quality are reduced
Solution Approach 1:
The patent applies preliminary action by detecting the shooting posture and reconstructing the thumbnail image orientation before display. The posture detection unit captures orientation information during image capture, and the thumbnail image generation unit pre-reconstructs vertically framed images to match horizontal display orientation, ensuring high visibility without complex real-time processing during display.
2Device complexity
If shot images are displayed in the same direction as the camera posture, then the display method is simple, but the horizontal and vertical directions of vertically framed images become inconsistent with shooting direction
Solution Approach 1:
The patent implements feedback by using the posture detection unit to continuously monitor camera orientation during shooting, and feeding this information back to the thumbnail image generation unit. This feedback mechanism automatically adjusts the thumbnail reconstruction based on detected shooting posture, ensuring consistent image orientation without manual intervention while maintaining reasonable system complexity.
3Adaptability or versatility
If a rotation state detection unit and addition unit are added to detect and record shooting posture, then image posture can be preserved in display, but the device complexity increases
Solution Approach 1:
The patent applies universality by integrating posture detection functionality into existing camera components rather than adding completely separate systems. The posture detection unit leverages the camera's existing orientation sensing capabilities, and the thumbnail image generation unit combines posture detection, image reconstruction, and display preparation in a single integrated component, reducing overall device complexity while maintaining adaptability.

AI summary
An imaging device includes a display unit for displaying an image, an imaging optical system, an imaging unit, a posture detector for detecting a posture of the imaging device in shooting, a recording unit for recording a reduced image of a shot image, and posture information on a posture of the imaging device corresponding to the reduced image, an image extracting unit for extracting reduced images including the same posture information among said reduced images recorded on the recording unit, and an image display controller for displaying the reduced images extracted by the image extracting unit on the display unit, wherein the image display controller reconstructs, on the basis of the posture information, a horizontal and vertical direction of the reduced images extracted by the image extracting unit to the posture of the imaging device in shooting, and displays the reduced image being reconstructed on the display unit. Thereby, that makes it possible to display a comfortable reduced image.
