Abstract
A camera includes (i) a detection circuit for detecting a relative moving state or a vibrating state between the camera and an object and (ii) a focusing adjustment apparatus for focusing on the object. The focusing adjustment apparatus is capable of performing a focusing operation in different focusing areas and locking the focusing area to a predetermined focusing area based on a result of a detection by the detection circuit.
Claims15
A cameras comprising:
- (a) a detection circuit for detecting a relative moving state or a vibrating state between said camera and an object:
- and
- (b) a focusing adjustment apparatus for focusing on the object, said focusing adjustment apparatus being capable of performing the focusing operation in different focusing areas and locking the focusing area to a predetermined focusing area based on a result of a detection by said detection circuit.
A camera comprising:
- (a) a detection circuit for detecting a relative moving state or vibrating state between said camera and an object:
- and
- (b) a focusing adjustment apparatus for focusing on the object, said focusing adjustment apparatus selecting a focus detection area on the basis of a detection result detected by said detection circuit,
- wherein said focusing adjustment apparatus comprises a plurality of sensor units for respectively receiving light beams from objects on different areas of an imaging field, and selects a sensor unit from among said plurality of sensor units in accordance with the detection result detected by said detection circuit, and
- wherein the sensor unit comprises a sensor unit for receiving a light beam from a central area of the imaging field.

3 more elements
A camera comprising:
- (a) a detection circuit for detecting a relative moving state or vibrating state between said camera and an object:
- and
- (b) a focusing adjustment apparatus for focusing on the object, said focusing adjustment apparatus selecting a focus detection area on the basis of a detection result detected by said detection circuit,
- wherein said focusing adjustment apparatus can select between a first focus detection area and a second focus detection area which is different from the first focus detection area, and selects one of the first and second focus detection areas in accordance with the detection result detected by said detection circuit, and
- wherein the second focus detection area is narrower than the first focus detection area.
2 more elements
A camera comprising:
- (a) a detection circuit for judging whether said camera is in a panning state;
- and
- (b) a focusing adjustment apparatus having (i) a one-shot mode in which focusing is inhibited once an in-focus state is attained and (ii) a servo mode in which an operation for focusing adjustment is repeated independently of an in-focus state or an out-of-focus state, said focusing adjustment apparatus operating in one of the modes based on a detection result of said detection circuit.
A camera comprising:
- (a) a detection circuit for detecting whether said camera is in a panning state in which the camera moves at a predetermined speed;
- and
- (b) a focusing adjustment apparatus for focusing on an object, said focusing adjustment apparatus selecting a focus detection area on the basis of a detection result detected by said detection circuit.
