Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a camera that has a zoom lens and is capable of cropping photography.

0002

[Conventional technology]

By cropping the top, bottom, left and right of the shooting screen when printing, it looks like a zoom. The result is a photo similar to that obtained with close-up shooting, while the shooting screen is By cropping the top and bottom of the image, it is as if you were taking a panoramic photo. There are known cameras that can take cropped pictures that can be used to take pictures with a 2-17149). In the following, the former will be referred to as pseudo zoom-up shooting. The latter is called pseudo-panoramic photography.

[Problem that the idea aims to solve]

However, with conventional cameras that allow cropping, zooming is not possible. The operating member and the operating member for setting the cropping shooting mode are provided separately. , both allow zooming operation, normal shooting mode and cropping shooting mode. However, it is difficult to operate the system because it requires switching between the two and three modes. To solve this problem, we have developed a system that allows you to switch zooming and shooting modes using a single operating member. Cameras that perform switching have been proposed (for example, Japanese Patent Laid-Open No. 2-17149) reference). However, this operating member can perform zooming and shooting modes depending on the operating stroke. Since the mode is changing the mode, there is a risk of erroneous operation.

0004 The purpose of this invention is to combine zooming operation and shooting mode switching operation into one operation. To provide a camera capable of cropping photography that can be operated reliably with members.
