  • Patent number: 11936861
    Abstract: Embodiments of this application relate to the video coding and compression field, and disclose an encoding method and apparatus, and a decoding method and apparatus, to resolve a problem that an existing split mode cannot satisfy a relatively complex texture requirement. The decoding method specifically includes: parsing a bitstream to determine a basic split mode for a current to-be-decoded picture block and a target derivation mode for a subpicture block of the current to-be-decoded picture block; splitting the current to-be-decoded picture block into N subpicture blocks in the basic split mode, where N is an integer greater than or equal to 2; deriving one derived picture block from at least two adjacent subpicture blocks in the N subpicture blocks in the target derivation mode; and decoding the derived picture block.

  • Publication number: 20230006418
    Abstract: A depth obtaining component includes a laser driver array and a laser array. The laser array includes a plurality of lasers. The laser driver array includes one or more control units, and each control unit is configured to control selection of one or more lasers in the laser array. The one or more control units are disposed in a charge loop of the laser driver array. A laser corresponding to the control unit can be flexibly selected based on a first switch module and a capacitive module in the control unit. In this way, scanning laser emission of the laser array can be implemented based on the laser drive circuit, no scanning device such as a micro electro mechanical systems mirror needs to be additionally disposed, and circuit support can be provided for implementing a small-sized, power-efficient, and cost-effective optical transmit end.

  • Patent number: 10897311
    Abstract: An optical signal modulation circuit includes a laser (DFB), a modulator (EAM), and an operational amplifier. The laser (DFB) generates a laser to stimulate the modulator (EAM) to generate a photon-generated current (ip), a first port (a) of the modulator (EAM) is connected to a first input voltage (Vbias), a second port (b) of the modulator (EAM) is connected to an inverting input end of the operational amplifier, a non-inverting input end of the operational amplifier is connected to a second input voltage (Vin), and an output end of the operational amplifier is connected to the first port (a) of the modulator. In the modulation circuit, a photon-generated current (ip) of the EAM is fed back to the operational amplifier, to implement a linear relationship between the second input voltage (Vin) and the photon-generated current (ip) of the EAM, and obtain a linear EML transmission curve, namely, a high-linearity EML.

  • Patent number: 10199010
    Abstract: The embodiments of the present disclosure provide a display driving system and a display apparatus. The display driving system comprises: a voltage adjustment circuit comprising an analog display signal input terminal, a trigger signal input terminal and an analog display signal output terminal. The voltage adjustment circuit is configured to adjust a blue voltage signal inputted to the analog display signal input terminal, in response to an adjustment trigger signal inputted to the trigger signal input terminal, to lower a light emission brightness corresponding to the blue voltage signal, and output the adjusted blue voltage signal via the analog display signal output terminal. In the display driving system, the adjustment trigger signal is inputted to the trigger signal input terminal and the blue voltage signal inputted to the analog display signal input terminal is adjusted, such that the blue voltage signal outputted from the analog display signal output terminal has a reduced amplitude.
