    Abstract: A circuit includes a comparator configured to generate a first conversion gain output signal by comparing a first pixel signal corresponding to a first conversion gain with a first ramp signal, and generate a second conversion gain output signal by comparing a second pixel signal corresponding to a second conversion gain with a second ramp signal, and a counter configured to count pulses of the first conversion gain output signal, output a counting result as a first digital signal, and determine whether an output of a second digital signal corresponding to the second conversion gain is required, based on the first digital signal. The first conversion gain is higher than the second conversion gain, and based on determining that the output of the second digital signal is not required, the counter is further configured to control the comparator such that the second conversion gain output signal is not generated.

    Abstract: A wireless audio device is provided. The wireless audio device includes an audio receiving circuit, an audio output circuit, an acceleration sensor, a communication circuit, a processor, and a memory. The memory may store instructions that, when executed by the processor, cause the wireless audio device to detect an utterance of a user of the wireless audio device by using the acceleration sensor, enter a dialog mode in which at least some of ambient sounds received by the audio receiving circuit are output through the audio output circuit, in response to detecting the utterance of the user, and end the dialog mode if no voice is detected for a specified time or longer by using the audio receiving circuit in the dialog mode.

    Abstract: According to an embodiment, disclosed is an electronic device including a speaker, a microphone, a communication interface, a processor operatively connected to the speaker, the microphone, and the communication interface, and a memory operatively connected to the processor. The memory stores instructions that, when executed, cause the processor to receive a first utterance through the microphone, to determine a speaker model by performing speaker recognition on the first utterance, to receive a second utterance through the microphone after the first utterance is received, to detect an end-point of the second utterance, at least partially using the determined speaker model. Besides, various embodiments as understood from the specification are also possible.
