Imaging Apparatus Panning Shot Exposure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imaging apparatuses fail to capture intended images with a blurred background and a moving object in focus, as they incorrectly adjust exposure control during panning shots, resulting in a stopped or clear background instead of a blurred one.
Innovation Solution
An imaging apparatus that detects motion and determines whether a panning shot is being taken, adjusting exposure control accordingly to allow for correct exposure and focus on the moving object while blurring the background.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If exposure control is executed based on motion detection to control object shake, then the object can be captured in focus, but the background becomes clear instead of blurred when panning shot is intended
Solution Approach 1:
The patent applies dynamics by making the exposure control adaptive based on detected motion patterns. The system dynamically adjusts exposure parameters according to whether panning motion is detected, allowing the same system to serve both stationary object photography and panning shot requirements without manual intervention.
Solution Approach 2:
The patent uses feedback by detecting motion in the captured image and using this information to adjust exposure control. The motion detection result feeds back into the exposure control mechanism, enabling the system to automatically distinguish between panning shots and stationary object photography and adjust accordingly.
2Reliability
If fast shutter speed is set when motion is detected, then object shake is controlled, but the background stream or blur effect is lost
Solution Approach 1:
The system dynamically adjusts shutter speed based on motion pattern recognition. When panning motion is detected, the system maintains slower shutter speeds to preserve background blur effects, while switching to faster shutter speeds only when stationary object photography is intended, thus adapting to different operational requirements.
Solution Approach 2:
The patent changes exposure parameters (shutter speed) based on detected motion characteristics. By analyzing motion patterns and determining whether panning is intended, the system adjusts the shutter speed parameter accordingly, allowing full range from slow (for panning) to fast (for stationary objects).

AI summary
An imaging apparatus (100) includes an imaging unit (103) configured to capture an image of an object to acquire image data; a display unit (107) configured to display the image captured by the imaging unit; a motion detection unit (115) configured to detect information about motion of the object and the background in a display image based on image data acquired by the imaging unit; a determination unit (116) configured to determine whether the imaging apparatus is taking a panning shot from a result detected by the motion detection unit (115); and an exposure control unit (102) configured to execute exposure control to decrease the amount of motion of the object and the background in the display image based on a result detected by the motion detection unit, wherein the exposure control unit executes exposure control based on a result detected by the motion detection unit (115) when the imaging apparatus is determined not to be taking a panning shot by the determination unit (116) and, when the imaging apparatus is determined to be taking a panning shot by the determination unit (116), executes different exposure control compared to a case when the imaging apparatus is determined not to be taking a panning shot.
