Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In bulb photography, users cannot check the brightness of the captured image during exposure, making it difficult to achieve desired image brightness.
Innovation Solution
An image processing apparatus that divides images captured over time into similar areas, generates a composite image through synthesis processing, and controls a display to show the composite image, ending synthesis based on user instructions.

1Duration of action of moving object
If continuous long-exposure imaging is performed without reading image signals, then the exposure can be maintained continuously to capture light trails and long-exposure effects, but the user cannot check the brightness of the captured image during exposure
Solution Approach 1:
The imaging area is divided into multiple regions, and image signal reading is performed selectively on specific regions during exposure. This allows the user to check brightness information in particular areas while maintaining continuous exposure in other areas, resolving the contradiction between continuous exposure and brightness monitoring.
Solution Approach 2:
Instead of reading image signals from the entire sensor array continuously (which would break exposure), the system reads signals from only partial regions at specific intervals. This partial action provides sufficient brightness information for user monitoring while preserving the continuous exposure function.
2Ease of operation
If image signals are read periodically during exposure and sequential addition synthesis is performed, then the user can check brightness changes and end exposure at desired timing, but the complexity of the imaging system increases
Solution Approach 1:
The imaging area is divided into multiple regions, and image signal reading is performed selectively on specific regions during exposure. This allows the user to check brightness information in particular areas while maintaining continuous exposure in other areas, resolving the contradiction between continuous exposure and brightness monitoring.
Solution Approach 2:
The system automatically performs synthesis processing to generate composite images from the read signal data, and the display device automatically displays these composite images. This self-service approach provides brightness monitoring functionality without requiring complex manual intervention or additional sophisticated hardware.

AI summary
An image processing apparatus includes at least one memory storing instructions, and at least one processor in communication with the at least one memory and configured to execute the instructions. Execution of the instructions causes the at least one memory and the at least one processor to divide each of a plurality of images captured continuously over time into similar areas, generate a composite image from the plurality of images by synthesis processing, and control a display device to display the composite image, wherein the synthesis processing for each of the areas divided by the dividing is ended based on an end instruction.
