A light measurement device includes a control device capable of switching between a measurement mode and a calibration mode, an optical system including a light irradiator that is capable of moving and irradiates an object to be measured with irradiation light, and a light blocking device including a shutter capable of blocking the irradiation light and calibrating the light measurement device. In the measurement mode, the positions of the shutter and the optical system are adjusted so that the shutter does not block the irradiation light and a focusing position of the irradiation light coincides with the position of the object to be measured. In the calibration mode, the positions of the shutter and the optical system are adjusted so that the shutter blocks the irradiation light and the focusing position of the irradiation light coincides with the position of the reference material.

Brillouin gain spectra are measured at low cost. An optical fiber characteristic measurement apparatus 10 according to the present disclosure measures the characteristics of an optical fiber 1 by the Brillouin optical correlation domain reflectometry method. The optical fiber characteristic measurement apparatus 10 includes a local oscillator 122 that generates a sinusoidal electrical signal, a mixer 121 that receives Brillouin gain spectra resulting from Brillouin scattering in the optical fiber 1 and the sinusoidal electrical signal generated by the local oscillator 122 and outputs down-converted Brillouin gain spectra, and a frequency analyzer 123 that measures the down-converted Brillouin gain spectra.

A method of processing one or more blocks of a picture is described. The method includes context mode level coding at least a part of one or more or all coefficients in a block in accordance with a context budget. The context mode level coding is continued when the context budget is exhausted.

A method of processing one or more blocks of a picture is described. The method includes predicting one or more chroma samples of a block of the picture using one or more luma samples of the block and one or more cross-component processes. One or more or all of the luma samples are clipped prior to being used in the one or more cross-component processes.

A method of processing one or more blocks of a picture is disclosed. The method includes obtaining a dominant angle for at least a part of a Spatial Geometric Partitioning Mode (SGPM) block.

A thermomechanical analysis apparatus with improved measurement accuracy is proposed. The thermomechanical analysis apparatus (1) includes a sample stage (15) where a sample (S) is placed, a sample tube (11) where the sample stage is placed, the sample tube being fixed to a measurement system, a probe (10) extending in an axial direction (L), one end of the probe (10) coming in direct or indirect contact with the sample (S) to apply a load to the sample (S) and a furnace (12a, 12b) configured to heat the sample, wherein a contact surface of the sample stage with the sample is provided with unevenness.

A method of processing one or more blocks of a picture predicts a block of the picture by combining a first prediction using a first angular intra prediction mode (IPM) and a second prediction using a second angular IPM. Each angular IPM is mapped to an intra angle. The first angular IPM is associated with a first intra angle equal to or greater than 180° or equal to or less than 90°, and the second angular IPM is associated with a second intra angle shifted by a predefined angle relative to the first intra angle. The first prediction is obtained by applying the first angular IPM on one or more reference samples on a first side of the block, and the second prediction is obtained by applying the second angular IPM on one or more reference samples on a second side of the block.

A method of providing a list of a plurality of intra prediction modes (IPM) for predicting one or more blocks of a picture, orders the plurality of IPMs in the list according to an estimated effectiveness of the respective IPMs for predicting a block of the picture.

A method of processing one or more blocks of a picture selects an intra prediction mode (IPM) from an IPM list, and uses the selected IPM for predicting a block of the picture. The IPM list is generated by adding to one or more first IPMs one or more second IPMs and/or three or more third IPMs. The one or more first IPMs are from one or more first reconstructed blocks at respective corners of the block. The one or more second IPMs are from one or more second reconstructed blocks adjacent to the block. The third IPMs have highest amplitudes among IPMs derived from reconstructed neighboring samples.
