1. An image signal processing driving method, applicable to an image signal processing module comprising a plurality of ISP cores or an ISP core supporting time division multiplexing, wherein the image signal processing module is equipped with a driver architecture, the driver architecture comprises an interface layer, a connection layer and a driver layer, and the driver layer is connected to the ISP cores or the ISP core; the method comprising:
receiving, by the interface layer, an image signal processing (ISP) instruction sent by an upper application, wherein the ISP instruction carries initial control parameters and image size parameters;
determining, by the connection layer, a processing mode of image signals according to the image size parameters, and determining target control parameters according to the initial control parameters for different processing modes, wherein the processing mode comprises a single-core mode or a multi-core mode; and
sending, by the driver layer, the target control parameters to a target ISP core, so as to drive the target ISP core to perform image signal processing according to the target control parameters.
