Specifically, in block 200, the sensor 25 is used to monitor the occurrence of an event (e.g., movement of an object or turning on of a switch). When the sensor 25 detects the occurrence of the event, a trigger signal is generated and transmitted to the image SoC 23 to wake up the image SoC 23. On the other hand, when the controller 233 of the image SoC 23 detects the trigger signal, the stage of block 210 is entered, and the image capturing system 2 is started.
When the image acquisition system 2 is started and image acquisition is performed, the stage of block 220 is entered, and the controller 233 of the image SoC 23 starts the operation of the system based on the trigger signal, and reads the program data RP20 of the ROM 231.

In addition, the user can write the corresponding image sensor data 21D into the non-read only memory 27 in advance according to the specification or type of the image sensor 21, so as to increase the flexibility of the system.

In some embodiments, the image SoC 33 is electrically connected to a non-read only memory 7. The components are electrically connected to transmit data and signals. The relevant image acquisition operations will be further described below.
Please refer to fig. 3B, which is a schematic diagram illustrating an operation sequence of the image capturing system 3 at different stages according to some embodiments of the present invention.

Specifically, in block 300, the sensor 35 is used to monitor the occurrence of an event (e.g., movement of an object or turning on of a switch). When the sensor 35 detects the occurrence of the event, a trigger signal is generated and transmitted to the image SoC 33 to wake up the image SoC 33. On the other hand, when the controller 333A of the image SoC 33 detects the trigger signal, the stage of block 310 is entered, and the image capturing system 3 is started.
When the image acquisition system 3 is started and image acquisition is performed, the stage of block 320 is entered, and the controller 333A of the image SoC 33 starts the operation of the system based on the trigger signal, and reads the program data RP30A of the ROM 331A.

In some embodiments, when the controller 333B of the image SoC 33 is triggered, the stage of the block 330 is entered, and the controller 333B reads the program data RP30B of the ROM 331B. The program data RP30B includes an image sensor start-up program. Accordingly, according to the program data RP30B of the ROM331B, the controller 333B of the image SoC 33 executes an image sensor start-up program for starting the image sensor 31 and controlling the image sensor 31 to acquire an initial image.
In some embodiments, when the controller 333B of the image SoC 33 executes the image sensor boot program, the controller 333B reads the image sensor data 31D associated with the image sensor 31 from the non-read only memory 37. The image sensor data 31D includes a plurality of programmable control commands and a plurality of parameters corresponding to the control commands.
In detail, since the image sensors 31 of different types or different specifications can be operated by different combinations of control commands, and each control command needs to be executed with parameters, the user can write the corresponding image sensor data 31D into the non-read only memory 37 according to the specification and type of the image sensor 31, and the controller 333B of the image SoC 33 is used when executing the image sensor start-up program.
Subsequently, when the image processing program is loaded into the non-read only memory 7, the stage of the block 340 is entered, and the controller 333A of the image SoC 33 sequentially executes: (1) starting a program for operating the starting of each module of the image SoC 33; (2) configuration setting of ISP; (3) an initial image is received.
Therefore, through the configuration of a plurality of pairs of controllers and ROMs, a plurality of programs can be dispersedly executed, so that the overall operation speed of the system is accelerated. In addition, by executing the image sensor start-up procedure in advance of the procedure related to the program data RP30B stored in the ROM331B, the image sensor 31 can be started up earlier, so that the processing of the first image (i.e., the initial image) can be completed more efficiently and quickly when the image processing procedure is executed. Furthermore, the user can write the corresponding image sensor data 31D into the non-rom 37 according to the specification or type of the image sensor 31, so as to increase the flexibility of the system.
