IMAGING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240137657 titled 'IMAGING APPARATUS
Simplified Explanation
The imaging apparatus described in the abstract includes features such as exposure control units, image processing units, and user-defined target brightness settings to enhance image quality and prevent overexposure.
- First exposure control unit: Suppresses overexposure of captured images.
- Image processing unit: Suppresses drop in brightness of low brightness regions based on the control amount of the first exposure control.
- Second exposure control unit: Adjusts brightness of high brightness regions closer to user-defined target brightness.
- Potential Applications of this Technology:**
- Photography equipment - Surveillance cameras - Medical imaging devices
- Problems Solved by this Technology:**
- Preventing overexposure in captured images - Maintaining consistent brightness levels across different regions of an image
- Benefits of this Technology:**
- Improved image quality - User customization options for brightness levels - Enhanced control over exposure settings
- Potential Commercial Applications of this Technology:**
- Camera manufacturers - Imaging software developers - Security system companies
- Possible Prior Art:**
One possible prior art could be the use of exposure control units in digital cameras to adjust brightness levels in captured images. However, the specific combination of features described in this patent application may be unique.
- Unanswered Questions:**
- How does the image processing unit determine the amount of brightness adjustment needed for low brightness regions?***
The abstract mentions that the image processing unit suppresses drop in brightness based on the control amount of the first exposure control, but it does not specify the exact method or algorithm used for this adjustment.
- What is the impact of the second exposure control unit on overall image quality?***
While the abstract states that the second exposure control unit adjusts brightness of high brightness regions closer to a user-defined target, it does not elaborate on how this adjustment may affect other aspects of the image, such as contrast or color accuracy.
Original Abstract Submitted
an imaging apparatus according to the present invention includes at least one memory and at least one processor which function as: a first exposure control unit configured to perform first exposure control to suppress overexposure of a captured image; an image processing unit configured to perform image processing to suppress drop in brightness of a low brightness region of the image on a basis of a control amount of the first exposure control; and a second exposure control unit configured to perform second exposure control to bring a brightness of a high brightness region of a captured image closer to a target brightness which is set by a user, wherein in a case where the second exposure control is performed, the first exposure control unit does not perform the first exposure control.
