Dynamic Zoom Control for Image-Capturing Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image-capturing systems face challenges in maintaining appropriate framing when objects or cameras move, leading to object-missing captures and inefficient use of recording media capacity, particularly with high-resolution video recording.
Innovation Solution
An image-capturing apparatus that dynamically adjusts the focal length and zoom factor using object and camera movement detection to switch between optical and electronic zoom, storing images in a way that minimizes object-missing captures and optimizes recording media usage by adjusting frame areas and compression rates based on movement and framing intentions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the zoom factor is increased to capture the object centrally, then the framing precision is improved, but the object may move out of the frame during recording
Solution Approach 1:
The system dynamically adjusts the zoom factor based on detected object movement. When movement is detected, the zoom factor is reduced to widen the field of view and prevent the object from moving out of the frame. This dynamic adjustment resolves the contradiction by making the framing adaptive rather than static, allowing the system to maintain both precision and reliability under varying conditions.
Solution Approach 2:
The system uses movement detection feedback to continuously monitor object position and adjust framing parameters accordingly. The movement detection unit provides real-time information about object displacement, which triggers automatic zoom factor adjustment. This feedback loop ensures that framing precision is maintained when the object is stationary while preventing frame-out when movement occurs.
2Manufacturing precision
If the focal length is increased to narrow the angle of view for better framing, then the manufacturing precision of the image is improved, but the recording time is reduced due to lower resolution coverage
Solution Approach 1:
The focal length is adjusted dynamically based on movement detection. When the object is stationary, a longer focal length is used to achieve higher image resolution. When movement is detected, the focal length is reduced to widen the angle of view and extend recording duration. This dynamic adjustment resolves the contradiction between resolution and recording time.
Solution Approach 2:
The system changes the focal length parameter in response to detected object movement. By varying this critical parameter, the system can switch between high-resolution narrow-angle framing for stationary objects and wider-angle framing for moving objects, thereby resolving the contradiction between image precision and recording duration.
3Measurement precision
If the zoom factor is set high to capture detailed images, then the image quality is improved, but the recording media capacity is consumed faster
Solution Approach 1:
The zoom factor is adjusted dynamically based on movement detection. High zoom factors are applied only when the object is stationary and detailed imaging is required, conserving media capacity. When movement is detected, the zoom factor is reduced, allowing longer recording times with the same media capacity. This resolves the contradiction between image quality and media capacity consumption.
Solution Approach 2:
The system periodically evaluates object movement and adjusts the zoom factor accordingly. Rather than maintaining a constantly high zoom factor, the system switches between high and low zoom levels based on movement conditions, thereby optimizing the use of recording media capacity while maintaining image quality when needed.

AI summary
To provide an image-capturing apparatus and an image-capturing method which keeps, even when an object or a photographer moves, the object-missing capturing to a minimum and which allows recording for a longer period of time. The image-capturing apparatus (100) includes: a focal length calculating unit (103) which calculates the focal length of the multifocal optical lens so that the zoom factor becomes smaller than a set zoom factor when movement is detected, and calculates the focal length so that the zoom factor becomes equivalent to the set zoom factor when movement is not detected; a recording media unit (108) for storing a captured image and the zoom factor along with time; a frame area setting unit (111) which sets, according to the zoom factor, a frame ICF to be clipped out of the captured image that is an output from the pickup device unit (104); an electronic zoom processing unit (112) which generates, through electronic zoom, a framing image (IDF) from the frame area (ICF); and a framing image display unit (113) which displays the framing image (IDF).
