Abstract
Auto focus control processing for still image recording is performed while continuously performing movie recording when an initiation instruction for a still image recording preparation process is issued during movie recording. Movie recording is interrupted to perform still image recording processing only when an initiation instruction for still image recording processing is detected during movie recording. In addition, in the auto focus control for still image recording during movie recording, focus detection is performed within a distance range that is narrower than the distance range during auto focus control performed for normal still image recording.
Claims5
An image sensing apparatus capable of recording still images during movie recording, comprising:
- an automatic exposure control unit adapted to perform an aperture value control processing for movie recording and to perform an aperture value control processing for still image recording when an initiation instruction for a still image recording preparation process is issued during the movie recording;
- and
- an image recording unit adapted to perform still image recording processing while continuously performing movie recording when an initiation instruction for still image recording processing is issued after the initiation instruction for a still image recording preparation process is issued,
- wherein the automatic exposure control unit performs the aperture value control processing for still image recording using an aperture value, which is being used for movie recording at the time when the initiation instruction for a still image recording preparation process was issued, as a minimum aperture value used for the aperture value control processing for still image recording.
A control method for an image sensing apparatus for recording still images during movie recording, comprising:
- controlling an aperture value for movie recording and an aperture value for still image recording when an initiation instruction for a still image recording preparation process is issued during movie recording;
- and
- recording still images while continuously performing movie recording when an initiation instruction for still image recording processing is issued after the initiation instruction for a still image recording preparation process is issued,
- wherein the controlling the aperture value for still image recording uses an aperture value, which is being used for movie recording at the time when the initiation instruction for a still image recording preparation process is issued, as a minimum aperture value used for controlling the aperture value for still image recording.
