Abstract: A method of executing an initial program load in an electronic device is provided. The electronic device includes a chip. The chip is connected with a storage device. The method includes the following steps. First, checking data and a characteristic value are read from the storage device. Then, an algorithm parameter is acquired from the checking data. Then, the checking data and the characteristic value are verified according to a specified checking algorithm and the algorithm parameter. If a result of the specified checking algorithm passes, a boot code is executed. If the result of the specified checking algorithm fails, a notification signal is issued.

Abstract: A display apparatus and an image capturing method are provided. The display apparatus includes a receiving unit, a processing unit, a display panel, a display output interface, and a capturing unit. The receiving unit is coupled to a data bus and receives video stream data provided by an external video source. The processing unit is coupled to the data bus and processes the video stream data to generate display data. The display output interface is coupled to the processing unit and the display panel, receives the display data, and drives the display panel to display an image frame. The capturing unit is coupled to the data bus and captures all or part of the image frame according to a capturing command issued by an external device, so as to obtain captured target data. The capturing unit also transmits the captured target data back to the external device.
