Abstract: A pixel of a vision sensor includes a photoelectric converter configured to convert an optical signal into a current, a current-to-voltage converter configured to convert the current into a first voltage, an amplifier configured to generate an output voltage by amplifying a voltage level of the first voltage, at least one comparator configured to identify whether an event occurs based on comparing the output voltage with at least one threshold voltage, and generate an event signal based on identifying that the event occurs, and at least one counter configured to receive the event signal from the at least one comparator, obtain a count value by counting the event signal as information about an amount of change in illumination, and transmit output data comprising the count value.

Abstract: An operation method of an image signal processing device includes receiving a raw pixel code from an external image sensor device including an image pixel, generating a non-linear pixel code by performing non-linear mapping on the raw pixel code, and outputting a downsized pixel code obtained by performing a masking operation on bit positions including a first bit position corresponding to a most significant bit of the non-linear pixel code and a second bit position corresponding to a least significant bit of the non-linear pixel code. An amplitude of the raw pixel code is linear to illuminance of a light incident onto the image pixel, an amplitude of the non-linear pixel code is non-linear to the amplitude of the raw pixel code, and the non-linear pixel code has a first code length, and the downsized pixel code has a second code length smaller than the first code length.

Abstract: An electronic apparatus is provided. The electronic apparatus includes a communication interface; a display; an internal speaker; and a processor configured to control the internal speaker to generate a first audio signal and control the communication interface to transmit a signal to control an external audio device to generate a second audio signal that is synchronized with the first audio signal. The processor is configured to: obtain a first processing time regarding the first audio signal and a second processing time regarding the second audio signal; and control the internal speaker and the communication interface based on the first processing time and the second processing time so that a difference between a first output timing of the first audio signal and a second output timing of the second audio signal is less than a predetermined value.
