Abstract: A follow focus device for a gimbal carrying an image capturing device includes a power assembly connected to the image capturing device, a connection member, and an adjustment member electrically connected to the power assembly. The power assembly is configured to adjust at least one lens parameter of the image capturing device. The connection member is configured to fix the power assembly to the gimbal. The adjustment member generates a control signal to adjust the lens parameter of the image capturing device. The power assembly receives the control signal from the adjustment member and, based on the control signal, rotates a part of the image capturing device to adjust the lens parameter of the image capturing device.

Abstract: An electronic device includes a slice splitter and a slice encoder. The slide splitter is configured to split video data into a plurality of slices. Each slice contains a plurality of data blocks and each data block contains a plurality of data points. The slice encoder includes one or more video encoding circuits and is configured to encode the data blocks in a plurality of data streams concurrently to obtain encoded data streams and combine the encoded data streams into a combined data stream.
