In the method, after a wide-view video of a specific conference, related conference event data, and speech content of each participant are obtained, a highlight video of the specific conference is correspondingly generated. Accordingly, the efficiency of conference viewing is improved.

A polyhedron lens architecture is disposed in a virtual sphere. The virtual sphere has a horizontal plane, an upper hemisphere above the horizontal plane and a lower hemisphere below the horizontal plane. The polyhedron lens architecture has an upper half part above the horizontal plane, and a lower half part below the horizontal plane. The polyhedron lens architecture includes: multiple bases, which are respectively disposed on the upper half part and the lower half part; and multiple lenses respectively disposed on surfaces of the bases. Optical axes of the lenses intersect at a central point, which is located at the horizontal plane and is a structural center of the polyhedron lens architecture.

An electronic device and data transmission protection device thereof are provided. The data transmission protection device includes an input clock signal detector and a control signal generator. The input clock signal detector receives a reference clock signal, and detects a frequency of an input clock signal provided by a host end according to the reference clock signal, and frequencies of the reference clock signal and the input clock signal are different. The control signal generator enables a generated control signal when the frequency of the input clock signal is larger than a safety setting value. The control signal is used to disable the host end to perform a data accessing operation on a protected circuit.

A testing device and a testing method for detecting a stitching defect of a panoramic camera are provided. The testing method includes: accessing the panoramic camera to obtain a stitched image, wherein the stitched image includes a chart image corresponding to a chart, wherein the chart includes multiple black stripes and multiple white stripes; generating a defect image marked with the stitching defect according to the chart image; and outputting the defect image.

A video content providing method and a video content providing device are provided. The method includes the following. A wide viewing angle image stream and a corresponding first audio content are obtained. A plurality of regions of interest in the wide viewing angle image stream are determined, and candidate regions in the regions of interest are integrated into a first frame. A designated region is selected from the candidate regions, and a corresponding first audio component are found from the first audio content. Each first audio component is suppressed to adjust the first audio content into a second audio content. The first frame and the second audio content are integrated into a specific video content, and the specific video content is provided.

A method of compensating for color differences between adjacent lens images in a panoramic image is disclosed. The method comprises: calculating color differences of each pair of character regions between any two adjacent lens images out of multiple lens images from a multiple-lens camera according to average color values of the character regions, each character region having a character point; determining color adjustment amounts of character points in each lens image according to the color differences of each pair of character regions; calculating a color adjustment amount of an element according to positions of the element and its two adjacent character points and the color adjustment amounts of the two adjacent character points.

An adaptive serial general-purpose input output (ASGPIO) interface and a signal receiver thereof suitable for a secure control module (SCM) are provided. The ASGPIO interface includes a signal transmitter. The signal transmitter includes a first data buffer, a comparator, and an encoder. The first data buffer receives transmitted data and provides previously transmitted data. The comparator receives currently transmitted data and receives the previously transmitted data. In a first mode, the comparator compares the previously transmitted data with the currently transmitted data to generate a data variation information. The encoder, in the first mode, generates at least one index value and a corresponding instruction signal according to the data variation information. The signal transmitter sends the at least one index value as a serial signal and the instruction signal to a signal receiver.

An image processing system is disclosed, comprising: an M-lens camera, a compensation device and a correspondence generator. The M-lens camera generates M lens images. The compensation device generates a projection image according to a first vertex list and the M lens images. The correspondence generator is configured to conduct calibration for vertices to define vertex mappings, horizontally and vertically scan each lens image to determine texture coordinates of its image center, determine texture coordinates of control points according to the vertex mappings, and P1 control points in each overlap region in the projection image; and, determine two adjacent control points and a coefficient blending weight for each vertex in each lens image according to the texture coordinates of the control points and the image center in each lens image to generate the first vertex list, where M>=2.
