no. 1 approach

[0068] Hereinafter, a first mode for implementing the present invention will be described with reference to the drawings. FIG. 1 is an external view of a portable handheld projector-equipped mobile phone 10 according to a first embodiment of the present invention. (a) is a front view, (b) is a side view, and (c) is a rear view. In FIG. 1 , a housing of a mobile phone with a projector 10 is composed of an operation unit 1 and a display unit 2 , and the operation unit 1 and the display unit 2 are connected by a rotatable folding hinge unit 3 . That is, the projector-equipped mobile phone 10 has a structure that can be folded with the hinge portion 3 as the center of rotation.

[0069] The operation unit 1 is provided with various operation keys for receiving user's operation input. The operation keys include the same keys as those of a general mobile phone having a camera function, mail sending and receiving function, network connection function, and the like. For example, it...

[0180] A second embodiment of the present invention will be described. In this embodiment, the camera module has a zoom function, and can be moved to any zoom position through user operation during shooting. In this way, the user can zoom in or out to shoot the subject. In addition, since the appearance and structure of this embodiment are the same as those of the first embodiment, description thereof will be omitted here.

[0181] In the present embodiment, the imaging lens 71 of the camera module 7 is a variable-focus zoom lens, and is driven by the lens drive unit 73 under the control of the camera control CPU 74 to control its zoom position. The camera control CPU 74 controls the zoom position of the photographic lens 71 so as to attain a predetermined zoom position set in advance when a projected image is captured by the camera module 7 . That is, when the projector module 6 is used to generate a projected image, the camera module 7 automatically controls the photograph...

no. 3 approach

[0188] A third embodiment of the present invention will be described. FIG. 13 is an external view of a mobile phone with projector 10A according to the present embodiment. (b) and (b) are side views, (c) rear view. This mobile phone with projector 10A is composed of an operation unit 1 and a display unit 2A as in the first embodiment. In the display unit 2A, the projector module 6 and the camera module 7 are provided at positions shown in the figure, and the sub liquid crystal display 5 shown in FIG. 1 is not provided. Other than that, it is the same as the display unit 2 in the first embodiment.

[0189]The camera module 7 is disposed on the camera mounting mechanism portion 2B of the display portion 2A. The camera mounting mechanism section 2B has a rotatable mechanism for changing the shooting direction of the camera module 6 . Therefore, the imaging direction of the camera module 7 and the projection direction of the projector module 6 include the same direction shown ...

Abstract

A projector device includes: a projection image generation device for projecting an image onto a projection surface and generating a projection image of an image; an imaging device for acquiring an picked-up image of an object imaged; and a calibration control device for repeatedly executing calibration operation for adjusting appearance of the projected image on the projection surface during the projection of the projected image according to the picked-up image of the projected image imaged and acquired by the imaging device.

Description

technical field [0001] The present invention relates to a projector device that projects an image onto a projection surface and generates the projected image, such as a projection type liquid crystal projector using a liquid crystal display panel, and a handheld projector device built into a mobile phone or a camera. Background technique [0002] As projection type liquid crystal projectors, devices using light sources such as halogen lamps and xenon lamps are known. It separates the light output from the light source into three primary colors of red (R), green (G), and blue (B), which are respectively introduced into different liquid crystal display panels and then synthesized again after passing through, and the synthesized light is projected through the projection lens onto a projection surface such as a screen. However, in a projection-type liquid crystal projector using such a lamp light source, there is a disadvantage of increasing the size of the device because separ...
