Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to accurately capture and control droplets ejected from dispensers due to the limitations of high-speed cameras, which can only capture a few frames per droplet, making precise detection and control challenging.
Innovation Solution
An information processing apparatus and system utilizing an event-based vision sensor (EVS) to detect droplets by converting optical signals into event signals, enabling precise detection and control through a processor that analyzes temporal luminance changes to adjust droplet parameters.

Engineering Contradiction Analysis
1Power
If a user device transmits a capture image to a server device for processing, then the user device can utilize the server's processing power for complex image operations, but the communication load and data transmission requirements increase
Solution Approach 1:
The image processing task is segmented into two parts: preprocessing operations (such as format conversion, compression, or initial filtering) are performed locally on the user device, while only the processed or selectively extracted data is transmitted to the server for further processing. This segmentation reduces the volume of data that needs to be transmitted while still utilizing the server's processing power for complex operations.
2Manufacturing precision
If the server device processes images with high resolution and large file sizes, then processing quality is maintained, but communication time and network bandwidth consumption increase
Solution Approach 1:
The user device performs preliminary actions on the capture image before transmission, such as format conversion to more efficient formats, preliminary compression, or extraction of key regions of interest. This preliminary processing maintains the essential quality information needed for accurate processing while significantly reducing the data volume that requires communication, thereby reducing communication time without sacrificing processing quality.
3Manufacturing precision
If the system stores and processes original capture images, then image quality is preserved, but storage space and processing resources are consumed
Solution Approach 1:
The system changes the parameters of image storage and processing by maintaining original quality images only when necessary (such as when high quality is required for the specific application), while using compressed or processed versions for routine operations. The system dynamically adjusts between storing original images and processed images based on quality requirements, thereby reducing overall storage space consumption while preserving image quality when needed.

AI summary
The present technology relates to an information processing apparatus and an information processing system that enable accurate detection of a droplet from a dispenser. The information processing apparatus includes: an event sensor including a pixel configured to photoelectrically convert an optical signal and output a pixel signal, the event sensor being configured to output a temporal luminance change of the optical signal as an event signal on the basis of the pixel signal; and a processor configured to detect a droplet injected from the dispenser on the basis of the event signal. The present technology can be applied to, for example, a dispenser control system that controls a dispenser, and the like.
