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.

Abstract: A projection display apparatus may include alight 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.

Abstract: In an image capturing apparatus for carrying out TV-AF type autofocus control, a difference is provided between an AF frame set for a particular object detected in an image, for example, for a person's face, and a normal AF frame in the band of frequency components for use in the generation of an AF evaluation value. Specifically, an AF evaluation value is generated for the AF frame set in the face region based on components in a frequency band with the highest frequency lower than for the normal AF frame.
