Title:
PHOTOGRAPHING DRIVING CIRCUIT OF INTELLIGENT PEN
Document Type and Number:
WIPO Patent Application WO/2022/007138
Kind Code:
A1
Abstract:
A photographing driving circuit of an intelligent pen, relating to the technical field of intelligent pens, and comprising: a pressure sensor, wherein the pressure sensor is provided at the tip of the intelligent pen, and according to a press action of the intelligent pen, generates an intelligent pen activation signal; a processor, wherein the processor comprises a first interface, a second interface, and a third interface; a switching triode, wherein the base end of the switching triode is connected to the third interface, so as to generate a closing operation according to a driving signal; and a camera module, wherein the camera module is connected to the collector electrode of the switching triode and used for driving, after the switching triode generates the closing operation, a camera to transmit collected image information to the processor. The photographing driving circuit of the intelligent pen can quickly start a photographing information collection operation according to a pressure signal.
