Abstract: A conversion method for converting luminance of a video, including a luminance value in a first luminance range, to be displayed on a display apparatus includes: acquiring a first luminance signal indicating a code value obtained by quantization of the luminance value of the video; and converting the code value indicated by the acquired first luminance signal into a second luminance value determined based on a luminance range of the display apparatus, the second luminance value being compatible with a second luminance range with a maximum value smaller than a maximum value of the first luminance range and larger than 100 nit. This provides the conversion method capable of achieving further improvement.

Abstract: A display system includes a conversion apparatus converting video luminance including a luminance value in a first luminance range and a display apparatus connected thereto and displaying the video. The conversion apparatus includes a first acquisition unit, a first luminance converter, a second luminance converter, a quantization converter, and an output unit outputting a third luminance signal to the display apparatus.

Abstract: The present invention aims to develop a dedicated control device for a transfer apparatus and a transfer apparatus controller that enables labor-saving wiring work, and to provide a conveying apparatus that switches a destination to which a conveyed object is to be conveyed by way of the transfer apparatus controller. A transfer apparatus includes a main conveying passage 101 that conveys a conveyed object 125 in one direction, an auxiliary conveying passage 102 for conveying a conveyed object 125 in a direction crossing the main conveying passage 101, and a lifting and lowering unit 115 that generates a height difference between both conveying passages 101 and 102 by lifting or lowering at least one of the conveying passages 101 and 102.
