Abstract
Provided are an image processing device, the operating speed of which is increased by reducing mirror bounce, a photographing apparatus having the same, and a photographing method. The image processing device includes a mirror disposed to revolve with respect to a shaft, a first guide unit disposed in a path of revolution of the mirror to lessen vibration of the mirror when the mirror revolves, and a first elastic unit applying predetermined elastic force onto the first guide unit while being engaged with the first guide unit.
Claims19
An image processing apparatus comprising:
- a mirror installed to revolve with respect to a shaft;
- a first guide unit disposed in a path of revolution of the mirror to lessen vibration of the mirror when the mirror revolves;
- and
- a first elastic unit configured to apply a predetermined elastic force onto the first guide unit while being engaged with the first guide unit, wherein the first elastic unit is configured to apply the predetermined elastic force onto the first guide unit in one direction before pressure applied onto the first elastic unit reaches a predetermined threshold level, and configured to apply the predetermined elastic force onto the first guide unit in a direction which is substantially opposite to the direction when the pressure applied surpasses the predetermined threshold level.
A photographing apparatus comprising:
- a mirror installed to revolve with respect to a shaft;
- a first guide unit disposed in a path of revolution of the mirror to lessen vibration of the mirror when the mirror revolves;
- a first elastic unit configured to apply a predetermined elastic force onto the first guide unit while being engaged with the first guide unit, wherein the first elastic unit is configured to apply the predetermined elastic force onto the first guide unit in one direction before pressure applied onto the first elastic unit reaches a predetermined threshold level, and configured to apply the predetermined elastic force onto the first guide unit in a direction which is substantially opposite to the direction when the pressure applied surpasses the predetermined threshold level;
- a lens on which light is incident;
- an imaging device configured to convert energy of the incident light into an electrical signal;
- a display unit configured to display an image captured by the imaging device;
- and
- a mirror configured to change a direction of propagation of the incident light.
A method of photographing an image by using an imaging apparatus having an image processing device, the method comprising:
- (a) moving a mirror downward while revolving in a first direction;
- (b) when the mirror contacts a first guide unit and pushes the first guide unit in the first direction, applying, via a first elastic unit, a predetermined elastic force onto the first guide unit in order to allow the first guide unit to push the mirror in a direction opposite to the first direction;
- and
- (c) when the first elastic unit elastically deforms to a predetermined threshold level, applying, via the first elastic unit, a predetermined elastic force onto the first guide unit in order to allow the first guide unit to push the mirror in the first direction.
