Solution Overview
Problem
Existing image capturing technologies struggle with capturing satisfactory images of moving subjects and fail to handle various types of subjects beyond humans, particularly in ensuring eyes are open, leading to inadequate image selection.
Innovation Solution
An image capturing apparatus with an image-capturing unit, speed detection unit, and image-capture control unit that dynamically adjusts the image-capture time interval based on the subject's movement speed, along with an image analysis and selection unit to analyze and select preferred images based on user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a predetermined number of images are captured by continuous image capture, then a desired image can be selected from among the plurality of images, but there is no satisfactory image when the subject moves at high speed or with changing movement speed
Solution Approach 1:
The image capture time interval is dynamically adjusted based on the detected movement speed of the subject. When the subject moves faster, the capture interval is shortened to ensure satisfactory images are captured. This dynamic adaptation resolves the contradiction between maintaining reliable image capture and handling high-speed moving subjects.
2Productivity
If continuous image capture is performed at a fixed time interval, then the capture process is simple, but the probability of obtaining satisfactory images decreases when the subject moves quickly
Solution Approach 1:
The system detects the movement speed of the subject and uses this feedback information to adjust the image capture time interval. This closed-loop control ensures that the capture process adapts to the subject's motion, maintaining high productivity while improving the reliability of obtaining satisfactory images.
Solution Approach 2:
The image capture time interval parameter is changed dynamically based on the subject's movement speed. By adjusting this parameter in response to detected motion, the system optimizes both capture efficiency and image quality probability.
3Reliability
If the image capture time interval is shortened to capture high-speed moving subjects, then satisfactory images can be obtained, but the image capture frequency increases and may cause missed captures of other important moments
Solution Approach 1:
The system applies different capture strategies to different situations: when a moving subject is detected, the capture interval is locally adjusted to be shorter; when subjects are stationary or slow-moving, the normal capture interval is maintained. This localized adaptation optimizes both moving subject capture reliability and overall capture throughput.

AI summary
A mobile terminal having a camera function includes a camera unit for capturing an image of a subject, and an image-capture control calculation unit that controls an image-capturing operation performed by the camera unit and that also calculates a movement speed of the subject that is being captured by the camera unit. Then, when the camera unit is performing continuous image capture, the image-capture control calculation unit dynamically changes and controls an image-capture time interval at the time of continuous image capture in accordance with a movement speed of the subject.
