Method of reproducing multiple shutter sound and electric device thereof

摘要

A method and electronic device reproducing a multiple shutter sound that reproduces a same shutter sound or a series of different shutter sounds during the period where an image is being processed by transmitting two or more interrupts to a controller by an image signal processor and an electronic device thereof. The repetitive shutter sounds can indicate to a user that the image is still being processed, so that the user does not move the camera and affect the capture of the image. The method of reproducing a multiple shutter sound includes: receiving a command for shooting a photograph; processing an image in response to the command; and transmitting at least two interrupt to a controller such that the shutter sound is reproduced at least twice while processing the image.

1. A method of reproducing a multiple shutter sound, the method comprising:
receiving by a controller a command for shooting a photograph; processing by an image signal processor an image output from an image sensor in response to the command for shooting a photograph; transmitting by the image signal processor to the controller at least three shutter sound interrupts based on a number of times of transmission interrupt, as set by a user, during the image processing of a single frame of the image output, the at least three shutter sound interrupts being transmitted to the controller using an interrupt pin; and outputting the shutter sound at least three times in response to the at least three shutter sound interrupts, wherein at least one shutter sound interrupt is transmitted between a starting time of the image processing and a termination time of the image processing.
