  • Patent number: 10735662
    Abstract: A digital camera includes an imaging control unit that images a subject by performing driving based on a rolling shutter method on an imaging sensor, and a light emission control unit that emits auxiliary light a plurality of times from a light emission device while the imaging is performed. A difference ?t between start timings of exposure started by the driving in two adjacent pixel rows is a value other than 1/n (n is an integer greater than or equal to 1) of an exposure time in which the exposure is performed. The light emission control unit controls a light emission cycle of the auxiliary light to be a time that is m (m is an integer greater than or equal to 1) times the difference.

  • Publication number: 20200221050
    Abstract: A system control unit consecutively images a subject by driving based on a global shutter method, divides captured image data obtained by the imaging into a plurality of areas, and each time each area is generated, compares the generated area with the same area as the area in the captured image data generated by the imaging performed before the imaging, and detects a moving object from the area based on a result of the comparison. Based on a change in position of the detected moving object, the system control unit predicts a timing at which a trigger range TR set in the captured image overlaps with the moving object, and performs automatic imaging in a frame period that includes the timing.

  • Publication number: 20200213546
    Abstract: A digital camerathat includes an imaging sensor having a stop 2 arranged in front of an imaging surface includes an imaging control unit that starts exposure of pixels on the entire imaging surface at the same time and then, ends the exposure of the pixels at the same time in a state where light from a subject is incident on the imaging surface, by controlling an imaging sensor drive circuit which drives the imaging sensor, and a processr that sequentially changes an F number of the stop 2 to a plurality of values during a period from the start of the exposure until the end of the exposure. The processr controls a time in which the F number is maintained at each of the plurality of values to be a time that is based on a function indicating light transmittance characteristics of an APD filter.

  • Patent number: 7013060
    Abstract: An optic switch for cross-connecting input light signals incoming from inlet fiber cables to outlet fiber cables is disclosed that makes use of a holographic filter (5) having a series of preformed different speckle patterns, each in the form of a hologram (H1, H2, . . . ). Associated with input light signals guided past respective inlet passages (4in) of a multimode waveguide (4), different speckle patterns are formed by applying different control voltages across respective electrode pairs (10, 10a) provided thereon. These speckle patterns past a single outlet passage (4out) of the multimode waveguide (4) into which the inlet passages (4in) converge are joined together and enter the holographic filter (5) in which an input light signal is selectively switched, addressed and cross-connected to an outlet waveguide (2) through a region thereof where a formed speckle pattern coincides with a preformed speckle pattern. The multi mode waveguides (4) is formed in, e.g., a LiNbO3 photorefractive substrate (3).

  • Patent number: 6475450
    Abstract: A method for directly leaching a zinc concentrate in one of the stages contained in the hydrometallurgical process for the production of electrolytic zinc. The method comprises: a neutral leach step, a zinc concentrate leach step, and an iron oxidation step. In the zinc concentrate leach step, a neutral leach residue and an iron sediment returned from the iron oxidation step are repulped by the spent electrolyte followed by adding thereto zinc concentrate to extract zinc from the zinc concentrate by carrying out a leaching under atmospheric pressure and at a temperature of not lower than 90° C., but not higher than the boiling point of the solution. According to this method, the concentration of Fe(III) ions in the zinc concentrate leach solution is significantly increased. Due to this Fe(III) ion concentration, the leaching rate of the zinc concentrate is enhanced.

  • Patent number: 5568529
    Abstract: A signal disconnection detection apparatus includes a first counter, a first comparator, and a detector. The first counter is reset by a pulse signal received every predetermined period of a clock signal, and counts a clock signal transmitted together with data. The first comparator compares a count value of the first counter with a set value larger than the number of clock signals included in one period of the pulse signal, and stops an operation of the first counter when the count value of the first counter exceeds the set value. The detector detects that the count value of the first counter does not continuously change within a predetermined period of time to output a signal disconnection detection signal of at least one of the clock signal and the pulse signal.
