Disclosed is a method of training a neural network model, performed by a neural network model training device, the method including converting input data to a red, green, blue (RGB) image; calculating a correction constant based on a generation method of the input data; and training the neural network model using the correction constant.

Method and device for training neural network model to be robust to changes in brightness of input data

A display device includes a driving frequency calculator configured to divide output image data into central, intermediate, and peripheral images respectively corresponding to central, intermediate, and peripheral visual field regions, calculate spatial frequencies of the central image, the intermediate image, and the peripheral image, calculate critical flicker frequencies of the central visual field region, the intermediate visual field region, and the peripheral visual field region based on the spatial frequencies and based on viewing angles of the central visual field region, the intermediate visual field region, and the peripheral visual field region, and determine driving frequencies of the central visual field region, the intermediate visual field region, and the peripheral visual field region based on the critical flicker frequencies, and a display panel configured to display an image based on the output image data and based on the driving frequencies.

A medical headgear includes an ultrasound transducer and a headgear. The ultrasound transducer is configured to generate a low intensity ultrasound. The headgear supports the ultrasound transducer. The headgear includes a rear portion case including a slide guide configured to support an occipital and a support pad configured to support a crown. The headgear further includes a front portion case connected to the rear portion case to be slidably movable in one direction. The front portion case includes two temporal support pads configured to support both temporal portions.
