Provided is a microparticle sorting device provided with a voltage supply unit that supplies a drive voltage to a vibration element that applies a vibration to an orifice that generates a fluid stream, a control unit that controls a driving condition supplied to the vibration element on the basis of a relative relationship between a droplet discharged from the orifice and a satellite droplet present between droplets, and a sorting unit that sorts the droplet containing microparticles on the basis of optical information detected from the microparticles flowing through a flow path.

An information processing device includes a color conversion unit that performs color conversion on video data of a display video displayed on a display and to be imaged by using table information reflecting an inverse characteristic of a characteristic of the display.

The present disclosure provides a user equipment that includes circuitry that is configured to receive an indication of random access resources in essential system information broadcasted from a network; transmit an on-demand system information request to the network in a first random access resource of the indicated random access resources, wherein the first random access resource includes a random access preamble; and receive a Random Access Response that includes a Random Access Preamble Identifier corresponding to the transmitted random access preamble; wherein the indicated random access resources in the essential system information are respectively mapped to system information blocks which are not included in the essential system information.

The present technique relates to a decoding device and a decoding method, and an encoding device and an encoding method, capable of performing encoding and decoding independently in the time direction for each tile. A decoding unit generates a prediction image by performing, for each of tiles, motion compensation of a reference image within a co-located tile based on tile splittable information indicating that decoding is allowed for each of the tiles and motion vector information representing a motion vector used for generating encoded data of a decoding target current image when a picture of the current image is split into the tiles and decoded. The decoding unit decodes the encoded data using the prediction image. The present technique is applicable to a decoding device, for example.

A method is disclosed. The method comprises obtaining first data from a first 2D image of a scene and second data from a second 2D image of the scene. The method comprises determining a first 2D object mask of an object that appears in the first and second 2D images. The method comprises determining a second 2D object mask of the object. The method comprises generating, for the first 2D object mask, a first depth map comprising first information indicative of a distance from the object to the camera. The method comprises determining a first scale parameter and a first shift parameter based on projecting the first information onto the second 2D image. The method comprises generating a second depth map based on the first scale parameter and the first shift parameter, the second depth map comprising second information indicative of the distance from the object to the camera.

The present disclosure relates to an image processing apparatus and method capable of suppressing a reduction in encoding efficiency.An upper limit value of the number of bins allocated to a processing target subblock by distributing the number of bins among nonzero subblocks is set, a syntax element value regarding the processing target subblock is derived by using coefficient data derived from image data so that the number of bins does not exceed the upper limit value, and the syntax element value derived is encoded and coded data is generated. The present disclosure can be applied, for example, to an image processing apparatus, an image encode apparatus, an image decode apparatus, a transmitting apparatus, a receiving apparatus, a transmitting/receiving apparatus, an information processing apparatus, an imaging apparatus, a reproducing apparatus, an electronic device, an image processing method, an information processing method, and the like.

To provide a communication apparatus which controls channel access operation under a multi user environment, and a communication method. Channel access operation of each STA after an MU mode is finished is controlled through a trigger frame from an AP to prevent collision immediately after the MU mode is finished. Further, the AP sets a smaller CW upon transmission of the trigger frame than a CW of an STA to preferentially transmit the trigger frame and give priority to communication in the MU mode over communication in an SU mode. Further, by the CW of each STA upon switching of the mode being not reset, a transmission waiting period after the MU mode is finished is shortened.

An electronic device is disclosed. The electronic device comprises memory circuitry, an interface and processor circuitry. The electronic device is configured to obtain image data from a plurality of image sensors, wherein the image data comprises a plurality of two-dimensional coordinates associated with a set of respective objects. Optionally, at least two image sensors of the plurality of image sensors have an overlapping area of their fields of view. The electronic device is configured to generate, based on the image data, three-dimensional coordinates associated with the set of respective objects. The electronic device is configured to determine, based on the three-dimensional coordinates, a recalibration parameter. Optionally, the recalibration parameter is indicative of a need for recalibration of at least one of the plurality of image sensors. The electronic device is configured to control, based on the recalibration parameter, provision of an alert message.

For displaying a stored photographic image, an auxiliary image is captured, and light direction information is determined from the captured auxiliary image. On the basis of the determined light direction information, a lighted image is generated from the stored photographic image. The lighted image is then displayed.
