JP3141434U - A camera having a finder characteristic that the size of the entire image of the funder screen seen when looking through the eyepiece lens is the same as the size of the entire 35 mm full size image even in a camera other than the image sensor 35 mm full size. - Google Patents

Abstract

In a lens mounted in conformity with the standard of an image sensor, an image of the entire finder screen seen when looking through an eyepiece lens is made small and looks as large as a 35 mm full size image.
An image sensor and an electronic viewfinder screen are electrically connected via an electrical conversion element, and an image captured by the image sensor is displayed on the entire electronic viewfinder screen. The size of the electronic viewfinder screen and the optical characteristics of the eyepiece allow the image seen when looking through the eyepiece to look the same as a 35 mm full size image.

Description

The present invention relates to a camera characterized in that the size of an image seen through an eyepiece is set to be the same size as a 35 mm full-size image.

Conventionally, in a lens mounted according to the standard of the image sensor, the image of the entire finder screen seen when looking through the eyepiece is small, which is the biggest drawback and feels uncomfortable.

Conventionally, in a lens that is mounted in accordance with the standard of the image sensor, the image of the entire finder screen that is visible when looking through the eyepiece is small, so that it looks the same size as the 35 mm full-size image It is.

An image pickup device, an electrical conversion device, a camera equipped with an electronic viewfinder screen and an eyepiece, wherein the image pickup device and the electronic viewfinder screen are electrically connected via an electric conversion device. The size of the electronic viewfinder screen and the optical characteristics of the eyepiece lens configured to display the image captured by the electronic viewfinder screen as a whole are 35 mm full size when viewed through the eyepiece lens. The problem is solved by setting it to look the same size as the video.
Referring to FIG. 1, an image of a subject taken by a 3 image sensor through 2 lenses is displayed on the entire 5 electronic viewfinder screen by electrically adjusting the magnification of the image via 4 electrical conversion elements. The entire image of the 6 electronic viewfinder screen is displayed so as to look the same size as the 35 mm full size image. At this time, the size of the electronic viewfinder screen is set to the same size as the entire screen of the above image. Has been.

The fact that it can be seen at a size of 35 mm full size has the same value as a 35 mm full size camera. Therefore, it is important to make use of the characteristics of the lens that is mounted, so that you can see powerful images, and to help you make images of the finished photo when shooting.
A conventional viewfinder has a small image in relation to a lens mounted in accordance with the standard of the image sensor, and feels uncomfortable. In the camera of the present invention, the image of the focal length converted to the 35 mm full size is displayed as the image of the same focal length as that of the 35 mm full size for the attached lens. The field of view is 100%.
If the electronic viewfinder is set in advance, the lens interchangeable type has the same function as a so-called 35 mm full-size single-lens reflex camera, but does not require a mirror or a pentaprism.
If a mirror is not required, the space between the image pickup device and the lens can be widened, and if the image pickup device is hermetically installed in a transparent glass box, dust on the surface of the image pickup image pickup device can be prevented. In addition, garbage attached to the glass box can be easily cleaned. It is also possible to attach a dustproof filter to one side of the glass box, like a lens filter. If this filter is removed and cleaned cleanly, it will be easier and no special dust protection measures will be required. Therefore, the camera can be easily and safely changed to a lens interchangeable type.

The best mode is implemented in an electronic viewfinder type digital camera.
Referring to FIG. 1, one subject is photographed by three image sensors through two lenses. This is displayed on a 5-electronic viewfinder screen via 4 electrical conversion elements. At this time, adjust the size of the electronic viewfinder screen and the magnification of the image of the electrical conversion element so that the image of the 6 electronic viewfinder screen seen through the eyepiece looks the same size as the image of the 35 mm full size screen. Keep it.

Since it is a device based on a completely new idea, it has not been implemented yet. Therefore, it is implemented based on the above description.

It is a work drawing of the Example for guide | inducing the finder effect of this invention.
