Problems solved by technology

However, for wide-angle light-sensing, the existing technology often uses 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 120 degrees

Abstract

The invention provides an educational behavior intelligent monitoring device based on a wide-angle camera and a manufacturing method thereof. The sensor substrate of the present invention has a main chip area and a plurality of auxiliary chip areas surrounding the main chip area. This combination can ensure the imaging uniformity of the facing area and the edge area, prevent the imaging distortion of the edge area, and make all The light-receiving surface of the sensor substrate is formed in a protrusion shape to obtain a larger imaging angle. The resulting camera and monitoring equipment have strong reliability, wide monitoring angle of view, and convenient control.

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...
