Abstract: A prediction processing system includes a processing circuit and a reference data buffer. The processing circuit performs a first inter prediction operation upon a first prediction block in a frame to generate a first inter prediction result, and further performs a second inter prediction operation upon a second prediction block during a first period. The reference data buffer buffers a reference data derived from the first inter prediction result. The processing circuit further fetches the reference data from the reference data buffer, and performs a non-inter prediction operation according to at least the reference data during a second period, wherein the second period overlaps the first period.

Abstract: A detection system and a detection method are provided. The detection method includes: receiving an image containing a face by an angle acquisition module and obtaining a first angle, a second angle and a third angle of the face based on the image; obtaining a first projection value and a second projection value based on the first angle, the second angle and the third angle by a projection calculation module; and performing by a confidence calculation module: performing an exponentiation calculation on the first projection value based on a first correction value to obtain a third value; performing an exponentiation calculation on the second projection value based on a second correction value to obtain a fourth value; and obtaining a confidence value based on the third value and the fourth value.

Abstract: A light guide element and a light source device using the same are provided. The light guide element has a main body. The main body has a hollow portion with a cone shape and a microstructure pattern formed on the main body. The cone-shaped hollow portion has a bottom portion and a top portion. The bottom portion is located on the bottom surface of the main body, and has a first hollow cross section area. The top portion is opposite to the bottom surface, and has a second cross section area smaller than the first cross section area. The microstructure pattern includes high-density areas and low-density areas to improve a light distribution caused by the cone-shaped hollow portion. The light source device includes the light guide element and a ht emitting diode (LED). The LED is used to emit light into the cone-shape hollow portion through the bottom portion.
