Problems solved by technology

However, the traditional camera is not only assembled or structured mechanically, so the traditional aperture positioning uses a sensing part (home switch) as a reference point, and the size of the aperture is judged based on the number of steps offset from the sensing part. However, the sensing part is composed of an elastic component, a fixed cylinder, and a sensing switch. Therefore, due to factors such as mechanical errors and unstable bouncing of the sensing part, there will be a shift in the sensing part, resulting in the opening of the aperture. error, which affects the performance of the camera to take pictures

Embodiment Construction

[0029] Please refer to FIG. 1A and FIG. 1B , which are schematic diagrams showing the front view structure of the first action and the second action of the preferred embodiment of the multi-segment aperture positioning device of the digital camera of the present invention. The digital camera of the present invention has a stepping motor 1 , a shutter part 2 and a sensing part 3 , and the stepping motor 1 can perform a rotational displacement movement of forward 91 and backward 92 . And the shutter part 2 has: a first shutter piece 21 and a second shutter piece 22, the first shutter piece 21 is connected with the stepping motor 1, because the stepping motor 1 also has a gear 11, so the The first shutter piece 21 is also provided with a toothed portion 213 for alignment connection with the gear 11, so that the stepping motor 1 can accurately drive the first shutter piece 21 when performing a rotational displacement movement, so when the stepping motor 1 When performing rotationa...

Abstract

A method for positioning multisection of light ring on digital camera includes leaning sensing element close to shutter to provide the first signal and separating said sensing element from said shutter to provide the second signal, activating digital camera and detecting whether the first signal is provided or not, advancing the stepping motor SM if it is then detecting whether the second signal is provided or not, checking whether phase of SM is correct or not if it is, advancing SM if phase of SM is correct ,check whether phase of SM is at maximum light ring position or not and regulating light ring properly for picking up image if it is .

Description

technical field [0001] The invention relates to a method for positioning the aperture of a camera, in particular to a method for accurately positioning a digital camera by using the phase of a stepping motor. Background technique [0002] With the development of science and technology and the strong demand of consumers, various information products and equipment have emerged accordingly, and the camera is one of the important inventions. It not only provides modern people with a moment of good time, but also provides some important things. Leave proof. Due to the need for frequent carrying of cameras and the development of modern electronic products, these products all tend to be short, light and thin. [0003] The lens part of the camera has always been the most important part of the camera, and adjust the aperture to adapt to changes in the intensity of external light to obtain the best shooting quality. However, the traditional camera is not only assembled or structured...
