    摘要： A distance measuring system and a controlling method of the system can reduce power consumption of a distance measuring apparatus acquiring an image including distance information. For example, the distance measuring system includes a distance measuring apparatus acquiring distance information concerning an image capturing target, a calculating unit estimating an estrangement period in which the image capturing target cannot be recognized in an image, based on the distance information, and a controlling unit setting the distance measuring apparatus to a power saving mode of controlling an acquiring frequency of the image according to the estrangement period when the estrangement period is a first threshold value or more, and setting the distance measuring apparatus to a normal mode of controlling the acquiring frequency of the image independently from the estrangement period when the estrangement period is less than the first threshold value.

    摘要： A photoelectric conversion apparatus including a plurality of pixels each having: a photoelectric conversion unit; a first charge holding unit; a second charge holding unit; a first gate; and a second gate. In a period when the photoelectric conversion unit is storing charges to be transferred to the first charge holding unit, the potential of the first gate is set to a first potential, and the potential of the second gate is set to a second potential. Both the first potential and the second potential are higher than the potential of the first gate in a period when the charges of the photoelectric conversion unit are transferred to the first charge holding unit and the potential of the second gate in a period when the charges of the photoelectric conversion unit are transferred to the second charge holding unit. The first potential is lower than the second potential.

    摘要： A display device includes signal supply circuit having N blocks and data supply circuit for supplying data to the N blocks. Each block includes holding block having k data holders for supply signals to k columns, and scanning circuit block for sequentially selecting the k data holders to receive data from the data supply circuit. The scanning circuit block includes k-stage shift register formed from k registers. Scanning circuit is formed by N scanning circuit blocks each arranged in one of the N blocks, and sequentially selects the N holding blocks each arranged in one of the N blocks to sequentially select the k data holders of each selected holding block to receive data. In response to output from i-th register of n-th block, the data supply circuit sets (n+1)-th block in operation-enabled state.
