Abstract
Description
technical field
[0001] The invention relates to the field of semiconductor chip packaging, in particular to an image sensor device, a camera based on the image sensor, and an educational behavior intelligent monitoring device based on the camera and a manufacturing method thereof. Background technique
[0002] In the current educational activities, it is necessary to use monitoring equipment to supervise the learning behavior of students, which is mainly based on the monitoring behavior of the camera. The basic component of the camera is the image sensing component, that is, the image sensor device of the present application, whose stability and viewing angle directly affect the reliability of monitoring. However, for wide-angle light-sensing, the existing technology often adopts a single sensor chip to form a concave shape on the light-receiving surface, which often causes imaging distortion in the edge area, and its camera angle is still relatively small, for example, only...
