Image projecting and capturing system and method

Abstract

The invention relates to an image projecting and capturing system and method. The image projecting and capturing system comprises an image projecting subsystem for projecting an image and an image capturing subsystem for capturing an image, wherein the image capturing subsystem comprises a lens which is provided with a plurality of lens group moving along an optical axis; when an image capturing function is performed, the image projecting subsystem is arranged in a space outside the optical axis; and when an image projecting function is performed, the image projecting subsystem is moved onto the optical axis. The image projecting and capturing method comprises the following steps of: capturing an image by using a lens, wherein the lens comprises a plurality of lens groups; and projecting the image by using a projecting lens and a part of the plurality of lens groups. Due to the adoption of the system and the method, elements of a projector and a camera can be effectively integrated to meet the requirement of product minimization.

Description

technical field [0001] The present invention relates to a digital image system and method, in particular to an image projection and capture system and method combining image capture and image projection functions. Background technique [0002] Digital cameras or video cameras have gradually become an indispensable electronic device in people's lives. People use them to take digital photos or digital images, and store them in the memory or memory card of digital cameras or video cameras. When people want to project these digital images, such as digital photos, short films, slides, etc., on a wall or a screen, they must first transmit these digital images to a computer or other electronic device, and then connect to an independent projector. The existing conventional free-standing projectors usually have the disadvantages of large volume, high noise, and high power consumption, and must be connected to an additional power supply. In addition, the conventional stand-alone pro...

Problems solved by technology

However, conventionally known products that combine projection and camera functions usually cannot effectively integrate components of the projector and camera (or video camera), and therefore occupy a relatively large amount of space.

[0004] It can be seen that the above-mentioned existing products combining projection and camera functions obviously still have inconvenience and defects in product structure, method and use, and need to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure and method for general products and methods to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve
