  • Patent number: 8878974
    Abstract: An imaging device is provided that includes a camera body, a lens barrel, a lens barrel information transmitter, and an image sensor driver. The image sensor is housed in the camera body. The lens barrel is attachable to and detachable from the camera body. The lens barrel information transmitter regularly transmits information of the lens barrel to the camera body. The image sensor driver drives the image sensor at one of at least two different frame rates where a second frame rate is higher than a first frame rate. The amount of data being transmitted is reduced by the lens barrel information transmitter when the image sensor is driven at the second frame rate, compared to the amount transmitted when the image sensor is driven at the first frame rate.

  • Patent number: 8873881
    Abstract: A dust detection system, comprising a receiver, a dust extraction block, a memory and an image correction block, is provided. The receiver receives an image signal. The dust extraction block generates a dust image signal on the basis of the image signal. The memory stores an intrinsic-flaw image signal corresponding to an intrinsic-flaw image including sub-images of dust that the dust extraction block extracts in initializing. The image correction block generates a corrected dust-image signal on the basis of the intrinsic-flaw image signal and a normal dust-image signal. The normal dust-image signal corresponds to a normal dust image including sub-image of dust that the dust extraction block extracts after initializing. The corrected dust image is the normal dust image that sub-images of dust in the intrinsic-flaw image are deleted from.

  • Patent number: 8830390
    Abstract: Provided is a digital camera including an electronic dial and a mode dial on an upper portion of a camera main unit, where upper surfaces of these dials approximately flush with an upper surface of the main unit, and are arranged in parallel with the optical axis of the main unit. The length from the upper end to the lower end of the mode dial is approximately the same as the length from the upper end of the electronic dial to a lower end of an encoder arranged below the electronic dial. This configuration forms a space in a box shape below these dials, and the space below the electronic dial can be efficiently used by setting the space as the storage portion for a recording medium to be inserted from the outside, resulting in downsizing the camera without sacrificing the operability.

  • Patent number: 8830381
    Abstract: An imaging device is provided that includes an image blur evaluator, an imaging processor, a distance map generator and a filter. The image blur evaluator evaluates the amount of blurring due to a camera shake. The imaging processor captures a plurality of secondary images of the same object at different lens positions by driving a photographing lens. The distance map generator prepares a distance map including distance information of the objects captured in each area of an image based on the contrast in each of the areas. The filter reduces noise in the distance map. A relatively large filter size is selected for the filter when blurring is evaluated to be relatively large and a relatively small filter size is selected for the filter when the evaluated blurring is relatively small.
