  • Publication number: 20220321785
    Abstract: A control apparatus includes a selection unit that selects a drive mode for first and second correction units based on a focal length, and a control unit that drives the correction units in the selected mode. The first correction unit moves an optical element. The second correction unit moves a sensor. The selection unit selects a first mode if the focal length is a first value, and selects a second mode if the focal length is a second value larger than the first value. With the first mode selected, if a shake amount is a threshold or less, the first correction unit is driven based on the shake amount, and if the shake amount is larger than the threshold, the correction units are driven based on the shake amount. With the second mode selected, the correction units are driven based on the shake amount and a drive ratio.

  • Patent number: 11403500
    Abstract: First quantization data for printing by the first nozzle group and second quantization data for printing by the second nozzle group are generated based on multi-valued data. By use of mask patterns, first print data and second print data are generated based on the first quantization data and the second quantization data. The first mask pattern for generating first print data and the second mask pattern for generating second print data are formed so as to include a pixel in which printing of a dot is allowed in both and a pixel in which printing of a dot is not allowed in both. The pixel value of each pixel indicated by the multi-valued data has a correlation with the sum of the number of dots indicated by the first print data and the number of dots indicated by the second print data in the area corresponding to each pixel.

  • Patent number: 11190695
    Abstract: A lens device is able to be installed in an imaging device via a mount part. The imaging device comprises a correction unit performing image blur correction through driving of an imaging element and a control unit which controls driving of the correction unit. The control unit determines a range of an amount of drive control of the correction unit on the basis of a difference between a second length and a positioning accuracy when the imaging element is positioned at the center of the mount part using the correction unit. The second length is obtained by subtracting a diagonal length associated with an imaging range of the imaging element from a first length corresponding to a closest distance to the center of the mount part from a circumference of an imaging circle when viewed from an optical axis direction of an imaging optical system included in the lens device.
