Embodiment Construction

[0042] Please refer to FIG. 1 which is an internal block diagram of the digital image capture device of the present invention.

[0043] The digital image capture device 10 of the present invention includes a processor 2

[0044] 1. The memory 22, the motor 23, the microphone 24, most of the buttons 25 and the lens 26 are electrically connected to each other. The digital image capture device 10 can be a digital camera or a digital video camera, but the present invention is not limited thereto. The processor 21 is used to control the memory 22 , the motor 23 , the microphone 24 and the lens 26 . The memory 22 can be a NAND flash memory, but the invention is not limited thereto. The memory 22 is used to store necessary application programs and an analog sound waveform database 31 . The analog sound waveform database 31 can be used to eliminate the sound generated when the motor 23 rotates. The method of establishing the analog sound waveform database 31 and eliminating the so...

Abstract

Being in use for a device of picking up digital image, the method eliminates sound of motor rotation when video recording carries through. The method includes following steps: inputting analog control signal; simulating working order of motor, and marking down analog sound waveform (ASW) of motor; establishing data bank of ASW; when video recording carries through, the device of picking up digital image uses ASW to eliminate sound of motor in dynamic film.

Description

technical field [0001] The invention relates to a method for eliminating motor sound, in particular to a method for eliminating motor sound by establishing an analog sound waveform. Background technique [0002] Video recording is an important function of a digital image capture device, and users usually record dynamic videos with the digital image capture device. When users are recording video, they often need to adjust the focal length or the distance lens and other functions by the rotation of the motor. When performing the above-mentioned functions, the sound of motor rotation in the digital image capture device may also be recorded in the video, thereby destroying the quality of the video. [0003] In order to solve the above-mentioned problems in the prior art, a one-way microphone or an external microphone is usually used to avoid recording the sound of the motor during video recording. However, if a unidirectional microphone is used, the structure of the digital im...
