Camera Metadata Storage for Post-Capture Image Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera systems lack the ability to store and utilize user-selectable image control options, such as depth of field and aspect ratio, at the time of image capture, leading to difficulties in post-processing where the original photographer's intentions may be lost due to lack of information about camera settings used during image capture.
Innovation Solution
A camera system that allows users to input and store image capture settings, including exposure time, depth of field, and aspect ratio, prior to or at the time of image capture, which are then used to generate composite images post-capture, simulating the intended effects and preserving the photographer's preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If post-capture editing is performed by a different individual than the photographer, then editing flexibility is improved, but loss of information about photographer's intended settings occurs
Solution Approach 1:
The system stores the photographer's intended settings and preferences at the time of image capture as metadata. This preliminary recording of preferences (such as desired depth of field, aspect ratio, and other image control options) ensures that when post-capture editing is performed by a different individual, the original photographer's intentions are preserved and can be automatically applied during composite image generation.
2Adaptability or versatility
If a large time gap exists between image capture and post-capture processing, then processing flexibility is improved, but loss of information about original intended settings occurs
Solution Approach 1:
The system records the photographer's intended settings and preferences at the moment of image capture. By storing this information as metadata alongside the captured images, the system ensures that even when significant time passes between capture and post-processing, the original photographer's intentions remain preserved and can be automatically retrieved and applied during composite image generation.
3Productivity
If photographer inputs settings at the time of capture, then post-processing efficiency is improved, but device complexity increases
Solution Approach 1:
The camera system incorporates a metadata storage mechanism that serves multiple functions: it stores camera capture settings, photographer's intended settings, and image control options all in a unified structure. This multi-functional approach allows the system to handle various types of information uniformly, improving post-processing efficiency without proportionally increasing device complexity.

AI summary
A camera device including multiple optical chains receives user input indicating one or more user selectable control option setting(s), e.g., a user selected depth of field control option setting and an aspect ratio control option setting. The indicated control option settings are stored in memory in the camera device. Multiple optical chains of the camera device capture an image during an image capture time interval. A set of captured images are stored in a file along with metadata including the user indicated control option settings. A composite image is generated from a set of captured images in accordance with the stored indicated control option settings, e.g., generating a composite image with a user selected depth of field and/or a user selected aspect ratio. In some embodiments, at least some of the user selected control option settings are not used during image capture operations but are used in subsequent image processing.
