Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image capturing apparatuses face challenges in obtaining high-quality images during continuous photography modes due to difficulties in setting optimal exposure times and number of images to be combined, particularly when considering various conditions such as camera shake and object motion.
Innovation Solution
An image capturing apparatus with a processor and memory that sets different continuous photography modes based on photography speed, acquires object and camera shake information, and controls exposure conditions to determine the number of images to be combined for image combination, ensuring high-quality image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the number of images to be combined and sensitivity are set by the same method regardless of continuous photographing mode settings, then the control process is simplified, but it becomes difficult to set the number of images to be combined and sensitivity suitable for the characteristics of the continuous photographing mode
Solution Approach 1:
The patent applies dynamics by making the control parameters (number of images to be combined and sensitivity) variable according to the continuous photographing mode. The control unit dynamically adjusts these parameters based on the selected mode (first continuous photographing mode or second continuous photographing mode), allowing the system to adapt to different characteristics of each mode while maintaining a unified control structure.
2Productivity
If automatic exposure control is not always performed during continuous photographing operation in high-speed continuous photographing mode, then the processing load is reduced, but it becomes difficult to always obtain proper exposure
Solution Approach 1:
The patent applies parameter changes by adjusting the automatic exposure control behavior based on the continuous photographing mode. In the first continuous photographing mode (higher speed), automatic exposure control is not always performed to maintain high productivity. In the second continuous photographing mode (lower speed), automatic exposure control is always performed to ensure proper exposure accuracy. The control unit changes the exposure control parameters according to the selected mode.
3Reliability
If a high shutter speed program diagram is uniformly employed when camera shake is detected, then camera shake correction is improved, but it becomes difficult to set a shutter speed suitable for the characteristics of the continuous photographing mode
Solution Approach 1:
The patent applies local quality by implementing different shutter speed strategies for different continuous photographing modes when camera shake is detected. In the first continuous photographing mode, a first program diagram (higher shutter speed) is employed to effectively correct camera shake. In the second continuous photographing mode, a second program diagram (lower shutter speed) is employed to maintain suitability for the mode's characteristics. The control unit selects the appropriate program diagram based on the detected camera shake and the selected continuous photographing mode.

AI summary
An image capturing apparatus capable of obtaining a high-quality image according to a continuous photographing mode and a shake state. In the image capturing apparatus, a plurality of types of a continuous photographing mode which are different in continuous photographing speed are set, a motion of an object is acquired from an input image, and shake information concerning a shake of the image capturing apparatus is acquired. Exposure conditions for photographing are controlled based on a type of the continuous photographing mode, the motion of the object, and the shake information, and in a case where image combination is performed, the number of images to be combined is determined.
