An image sensor and an operating method of the image sensor may include a pixel array including a plurality of pixels; a controller configured to generate a pre-shutter driving signal associated with a pre-shutter operation, the pre-shutter driving signal generated before a first shutter operation and a first read operation corresponding to photographing a first frame is performed; a row driver configured to drive first control signals to the pixel array based on the pre-shutter driving signal, the first control signals associated with the pre-shutter operation; and the pixel array is configured to perform the pre-shutter operation in response to the first control signals, wherein levels of the first control signals correspond to levels of second control signals, the second control signals associated with the first read operation.

Image sensor and operating method thereof

A refrigerator is provided. The refrigerator includes a main body in which a storage chamber having an open front surface is provided, a door rotatably coupled to the main body to open or close the storage chamber, and a microphone device disposed on an upper end of the door and configured to receive a voice command, wherein the microphone device includes a microphone supported by a substrate and configured to receive voice data, a cover protruding upward from the upper end of the door and including a voice input hole passing through a front surface and a rear surface of the cover and a microphone hole vertically extending downward from the voice input hole so that the voice input hole and the microphone are connected, and a sealing member disposed between the substrate and the cover so that the substrate is in close contact with the cover.

Refrigerator

An image sensor is provided. The image sensor includes: a pixel array of pixels arranged in a row and column directions. A first pixel provided in a first row of the pixel array includes a first sub-pixel connected with a first metal line, a second sub-pixel connected with a second metal line, a third sub-pixel connected with a third metal line, and a fourth sub-pixel connected with a fourth metal line. When a read-out operation is performed on the first pixel, signals applied to the first through fourth metal lines are sequentially enabled. Based on the applied signals, at least a part of charges accumulated in the first through fourth sub-pixels is diffused to a first floating diffusion node. The first sub-pixel and the third sub-pixel are adjacent in the column direction, and the first sub-pixel and the second sub-pixel are adjacent in the row direction.

Image sensor

An image sensor includes a pixel including a first floating diffusion and a second floating diffusion, generating a first pixel signal based on a quantity of charge of the first floating diffusion, and generating a second pixel signal based on the quantity of charge of the first floating diffusion and a quantity of charge of the second floating diffusion; a column line connected to the pixel and transmitting the first pixel signal or the second pixel signal; and a readout circuit connected to the column line and generating an image signal based on a plurality of comparison results including a first comparison result obtained by comparing the first pixel signal with a first reference signal, a second comparison result obtained by comparing the second pixel signal with a first reference signal, and a third comparison result obtained by comparing the second pixel signal with a second reference signal.

An air purifier or air conditioner including a filter device. The air purifier includes: a main body: a suction port provided to allow air to flow into the main body; a filter provided in the main body to filter the air suctioned from the suction port and including a frame and a filter body fixed to the frame; an auxiliary filter member separably mounted on the filter; and a locking device provided on the frame of the filter such that the auxiliary filter member is separably mounted on the frame of the filter.

Filter device and air cleaner having the same

Disclosed herein is a humidifier including an improved structure of a water collection tank. The humidifier includes a main body, a water supply tank provided in an upper portion of the main body, a humidifying fabric arranged in an inside of the main body and disposed below the water supply tank to receive water, a fan configured to move air through the humidifying fabric, a water collection tank configured to collect water from the humidifying fabric, a pump configured to pump water from the water collection tank to the water supply tank, and a humidifier lower cover coupleable to and decoupleable from a lower end of the main body. The water collection tank includes a water collection tank top cover provided in an upper portion of the water collection tank, and a water collection tank lower cover configured to be accessible through the lower end of the main body.

Humidifier

Provided is an image encoding method including generating a first picture reconstructed by using a residual picture and a predicted picture; generating a second picture by applying a first artifact reduction filter to the first picture; determining a picture having a smaller bit-rate distortion cost from among the first and second pictures by comparing a first bit-rate distortion cost of the first picture with a second bit-rate distortion cost of the second picture; generating a third picture by applying an in-loop filter to the determined picture; generating a fourth picture by applying a second artifact reduction filter to the third picture; determining a picture having smaller distortion from among the third and fourth pictures by comparing first distortion of the third picture with second distortion of the fourth picture; and generating, via a processor, a bitstream including information about whether the second artifact reduction filter is applied.
