Electronic device and method for improving camera zoom performance thereof

A method of improving a camera zoom performance performed by an electronic device, the method comprising:

• in case that a camera function is executed, acquiring, by an image signal processor, a first frame of a first zoom magnification from an image sensor;
• performing control to image-process a second frame to an Nth frame at a first zoom magnification through the image signal processor while the first frame of the first zoom magnification processed through the image signal processor is output on a display;
• receiving a user input requesting displaying at a second zoom magnification different from the first zoom magnification at a time point at which an (N+1)th frame is acquired;
• requesting the image signal processor to process the (N+1)th frame and transferring, to a scaler located behind an output terminal of the image signal processor, the second zoom magnification request at the time point at which the (N+1)th frame is acquired;
• and
• in an output order of the second frame, scaling a second frame processed at the first zoom magnification by the image signal processor to the second zoom magnification requested at the time point at which the (N+1)thì frame is acquired and outputting the second frame on the display by the scaler.

One or more non-transitory computer-readable storage media storing one or more computer programs including computer-executable instructions that, when executed by one or more processors of an electronic device individually or collectively, cause the electronic device to perform operations, the operations comprising:

• in case that a camera function is executed, acquiring, by an image signal processor, a first frame of a first zoom magnification from an image sensor;
• performing control to image-process a second frame to an Nth frame at a first zoom magnification through the image signal processor while the first frame of the first zoom magnification processed through the image signal processor is output on a display;
• receiving a user input requesting displaying at a second zoom magnification different from the first zoom magnification at a time point at which an (N+1)th frame is acquired;
• requesting the image signal processor to process the (N+1)th frame and transferring, to a scaler located behind an output terminal of the image signal processor, the second zoom magnification request at the time point at which the (N+1)th frame is acquired;
• and
• in an output order of the second frame, scaling a second frame processed at the first zoom magnification by the image signal processor to the second zoom magnification requested at the time point at which the (N+1)th frame is acquired and outputting the second frame on the display by the scaler.
