KR940015650A - Image stabilization device of zoom camera and its realization method - Google Patents

Abstract

By limiting the shutter speed, it narrows the operating range according to the brightness of the subject, and when it is out of the proper exposure range, it zooms toward the shorter focusing distance, minimizing the effects of hand shaking, and taking pictures in a proper exposure state. In order to achieve this, a motor drive unit for operating a barrel, a shutter driver for adjusting exposure, a switch unit for receiving an external input, a focusing unit for focusing and focusing, a detector for detecting the brightness of a subject, A microcontroller for controlling the operation of the camera and controlling proper exposure to the brightness of the subject when the focal length is long; When the shutter speed at the current zoom position is slower than the minimum shutter speed, the zoom camera performs the automatic zooming operation to the wide end where the focal length is shortened and the size of the subject is reduced, thereby preventing the photo from being shaken by hand shake. Of apparatus for reducing hand shake and method of realizing the same.

Motor driving unit for operating the barrel, shutter driver for adjusting exposure, switch unit for accepting external input, focusing unit for measuring the distance to the subject, detection unit for detecting the brightness of the subject, and camera functions And a micro-controller for controlling the above operation and controlling an operation of automatically zooming toward a shorter focal length so as to achieve proper exposure according to the brightness of the subject when the focal length is long. Camera shake reduction device. After initializing the internal circuit of the camera, open the lens cover after the power switch is applied, perform zooming operation according to the user's situation, set the appropriate shooting function according to the situation, and then release the first stage switch. Measure the subject's brightness according to the zoom position, measure the film's sensitivity, calculate the shutter speed based on the above information, and then determine whether the camera shake reduction function is set. If it is not, it determines whether the release two-stage switch is turned on.If the camera shake reduction function is set, it detects the current zoom position and calculates the minimum speed of another shutter at the zoom position, and the shutter speed of the current zoom position is the minimum shutter speed. If it is faster, it is determined whether the release two-stage switch is turned on, and the shutter speed according to the current zoom position is lower than the minimum shutter speed. In case of reel, the zoom motor is operated to operate the barrel in the wide direction from the current zoom position, and it is determined whether the zoom position is wide, and if it is not wide, the shutter speed is calculated again. However, it is determined whether the switch is turned on, and if the release two-stage switch is turned on, photographing is carried out, and after the film is transported, one end of the zoom camera is reduced. ※ Note: The disclosure is based on the initial application.
