Abstract: The present invention provides a MEMS microphone, including a housing body with a containment space, a sound hole penetrating the housing body, a MEMS microphone chip, an ASIC chip and a subtractor accommodated in the containment space. The MEMS microphone chip includes at least a first MEMS microphone chip and a second MEMS microphone chip. the first MEMS microphone chip is different from the frequency response droop characteristic of the second MEMS microphone chip. the first MEMS microphone chip and the output signal of the second MEMS microphone chip are output to the subtractor, and are output to the ASIC chip after the subtractor performs subtraction processing. Compared with the related art, the MEMS microphone of the present invention has good anti-interference performance and good sensitivity.
Abstract: An instruction transmission method is provided for an ambient lamp. The method includes: sequentially obtaining a playback frame from a playback frame sequence as a current playback frame; determining a target encoding scheme of the current playback frame based on a frame type of the current playback frame; determining effective data and a data type of the effective data of the current playback frame according to the target encoding scheme, and encoding the effective data into playback encoded data; and encapsulating the playback encoded data of the current playback frame and the data type of the effective data into a lighting-effect playback instruction, and transmitting the lighting-effect playback instruction to a control chip of a lighting component of the ambient lamp for execution.
Abstract: This application discloses an image rendering method and apparatus, an electronic device, and a storage medium, and belongs to the field of image processing technologies. The method includes: acquiring a lightmap of a target three-dimensional model in response to a light rendering instruction; acquiring a seam edge of the target three-dimensional model; determining, in the lightmap, a target pixel corresponding to the seam edge; and updating an initial pixel value of the target pixel in the lightmap to obtain a repaired lightmap. In this application, the seam edge of the target three-dimensional model is automatically identified, and the pixel value of the target pixel is automatically updated, so that automatic recognition and automatic repair of a seam problem can be completed by one click, thereby avoiding a waste of labor resources for troubleshooting and repairing the seam problem, reducing image rendering time, and improving image rendering efficiency.
