The present disclosure discloses an object detection method used in an object detection apparatus that includes the steps outlined below. An image signal received from an image sensor is detected to generate an image detection signal when an image variation is detected. An infrared signal received from an infrared sensor is detected to generate an infrared detection signal when an infrared energy variation is detected. A time counting process is initialized when the image detection signal is generated. An object detection signal is generated when the infrared detection signal is generated within a predetermined time period after the time counting process is initialized. A detection distance of the image sensor is larger than a detection distance of the infrared sensor.

Object detection apparatus and method

The present disclosure discloses a dual-processor electronic apparatus operation method used in a dual-processor electronic apparatus that includes steps outlined below. A first processor is activated in an initialization procedure. A second processor is activated by the first processor to enter an operation mode. The first processor is deactivated in the operation mode, and the second processor executes a predetermined procedure. Whether a predetermined event occurs during the execution of the predetermined procedure is determined by the second processor such that event information is stored when the predetermined event occurs and the first processor is activated. The event information is accessed and processed by the first processor.

Apparatus and method for lowering power dissipation based on operation between dual processors

A control method for a storage device of a driving recorder includes: configuring a directory entry of a storage device according to a predetermined directory entry stored in a storage unit; configuring a file allocation table of the storage device according to a predetermined file allocation table stored in the storage unit; and controlling a controller to write data to the storage device according to the directory entry and the file allocation table. In one embodiment, entries of the predetermined file allocation table are interleaved to accommodate multiple files and still support a continuous write operation.
