  • Patent number: 9402020
    Abstract: A focus detection apparatus detects a first subject region (e.g., face region) from an image signal, detects a second subject region (e.g., human body region), in which the first subject region can be estimated, from the image signal, and performs focus detection based on an image signal corresponding to the set focus detection area. In the case where the primary subject corresponds to the first subject region detected, the focus detection area is set to a first region, and, in the case where the primary subject corresponds to the first subject region estimated based on the second subject region, the focus detection area is set to a second region that is larger than the first region.

  • Patent number: 9210314
    Abstract: In a camera unit that is capable of attaching and detaching a lens unit, a camera control unit transmits a drive command for shifting a focus lens to a position corresponding to a focal point detected by use of an evaluation value for focus adjustment generated from an imaging signal by a TVAF signal processing unit to a lens control unit. The camera control unit acquires data indicating the amount of change in image magnification from the lens apparatus when performing center shift to thereby control the focus lens so as to suppress an out-of-focus blur of an image according to the image signal in response to the amount of change in image magnification relative to the shift amount of the focus lens in the vicinity of a focal point.

  • Patent number: 9148557
    Abstract: A focus adjustment apparatus comprises a detection unit that detects a subject/subjects having a predetermined characteristic from an image obtained while shooting a moving picture, a selection unit that, in the case where a subject/subjects having the predetermined characteristic have been detected by the detection unit, selects, from the detected subject/subjects, a subject that also fulfills a predetermined condition, and a focus adjustment unit that controls a focus lens to focus on the subject selected by the selection unit. The focus adjustment unit does not control the focus lens in the case where no subject having the predetermined characteristic has been detected by the detection unit.

  • Patent number: 9039206
    Abstract: A projection display apparatus may include a light source, a power supply unit, a detecting unit, a nonvolatile memory, a capacitor, and a control unit. The power supply unit supplies power from an external power supply to the light source power derived from the received power. The detecting unit detects a cut-off state in which no or no sufficient power is being received by the power supply unit. The capacitor accumulates charges in response to power being received. Following detection of the cut-off state and even after turning off the light source, the control unit is operable to carry out a data storage operation in which at least part of the data is stored in the nonvolatile memory, wherein power to carry out the data storage operation is obtained from the charges previously accumulated by the capacitor.
