Abstract
An imaging apparatus includes: a control unit configured to detect a focus position by moving a focusing lens before and after a preset position which is a focusing lens position set by a focus preset function, with the control unit setting a scan range which is a movement range of the focusing lens to a different range according to a setting state of a zoom lens, obtaining an AF evaluation value along with movement of the focusing lens within the set scan range, and determining a focus position based on the obtained AF evaluation value.
Claims16
An imaging apparatus comprising:
- a control unit configured to detect a focus position by moving a focusing lens before and after a preset position which is a focusing lens position set by a focus preset function;
- wherein said control unit sets a scan range which is a movement range of said focusing lens that differs according to a setting state of a zoom lens, obtains an autofocus (AF) evaluation value along with movement of said focusing lens within the set scan range, determines a focus position based on the obtained AF evaluation value, and performs processing for setting an AF evaluation value peak detection section, to which a different setting method is applied depending on a zoom lens position.
An imaging apparatus control method executed by an imaging apparatus, said method comprising:
- focus controlling arranged to cause a control unit to detect a focus position by moving a focusing lens before and after a preset position which is a focusing lens position set by a focus preset function;
- wherein said focus controlling includes setting a scan range which is a movement range of said focusing lens that differs according to a setting state of a zoom lens, obtaining an autofocus (AF) evaluation value along with movement of said focusing lens within the set scan range, determining a focus position based on the obtained AF evaluation value, and setting an AF evaluation value peak detection section to which a different setting method is applied depending on a zoom lens position.
A non-transitory computer readable storage medium having computer readable program codes embodied in the computer readable storage medium that, when executed cause an imaging apparatus to execute:
- focus controlling arranged to cause a control unit to detect a focus position by moving a focusing lens before and after a preset position which is a focusing lens position set by a focus preset function;
- wherein said focus controlling includes setting a scan range which is a movement range of said focusing lens that differs according to a setting state of a zoom lens, obtaining an autofocus (AF) AF evaluation value along with movement of said focusing lens within the set scan range, determining a focus position based on the obtained AF evaluation value, and setting an AF evaluation value peak detection section to which a different setting method is applied depending on a zoom lens position.
