Title:
IMAGE SENSOR
Document Type and Number:
WIPO Patent Application WO/2018/105246
Kind Code:
A1
Abstract:
The purpose of the present invention is to increase the speed of recognition processing using image data. An imaging element images an object and generates frames of image data arranged in time series. A binarization processing unit performs binarization processing on each of the frames to generate binarized frames. A tracking processing unit generates differences between adjacent binarized frames in time series and tracks the change in the position of the object included in the binarized frames. A moment generation unit calculates the moment of the object included in the binarized frames on the basis of the results from the tracking processing unit. A condition setting unit sets conditions for detecting a prescribed event from the image data. A detection unit detects the prescribed event by comparing the moment of the object with the conditions set by the condition setting unit. A control signal supply unit supplies a control signal to an output device in accordance with the detection results.
