Problems solved by technology
[0003] The current projection technology has successfully overcome the problem that the projection components of portable electronic devices are too large, but the disadvantage is that the projection output can only be adjusted by moving the portable electronic device by hand, and the output range cannot be adjusted effectively
Therefore, mobile phones on the market can already achieve the effect of projection. Since the traditional projection device in the mobile phone projects an image, it is impossible to know the output range of the projected image, so the image projected by the traditional projection device often does not meet the user's desire. The effect presented

The invention provides a projector and an operation method thereof. The projector comprises a storage module, a picture capture module, a picture identification module, an image processing module and an image output module, wherein the storage module is used for storing a projection data, the picture capture module is used for capturing a picture of a projection background, the picture identification module is coupled with the picture capture module and used for selecting a projection area on a picture, the image processing module is coupled with the storage module and used for converting theprojection data into an image, and the image output module is coupled with the picture identification module and the image processing module, and used for projecting the image on the projection area of the projection background. The operation method comprises the following steps: storing projection data, capturing a picture of a projection background, selecting a projection area on the picture, converting the projection data into an image, and projecting the image to the projection area of the projection background.
Description
technical field [0001] The present invention relates to a projection device, and in particular to a projection device with the function of dynamically adjusting the projection range. Background technique [0002] With the development of science and technology, consumer electronic products continue to introduce new ones. Especially various portable electronic devices, such as mobile phones, personal digital assistants (PDAs) and so on. [0003] The current projection technology can successfully overcome the problem that the projection components of portable electronic devices are too large, but the disadvantage is that the projection output can only be adjusted by moving the portable electronic device by hand, but the output range cannot be adjusted effectively. Therefore, mobile phones on the market can already achieve the effect of projection. Since the traditional projection device in the mobile phone projects an image, it is impossible to know the output range of the pro...
