Problems solved by technology

[0004] Conventionally, when the installation posture of a projector equipped with such a lens shift function is changed from a normal posture to a hanging posture, there is a problem that the pressing direction of the button of the lens shift function operated by the remote controller is different from that of the other. The direction of movement of the projection lens becomes inconsistent (moves in the opposite direction)

no. 1 Embodiment approach

[0035] Next, the projector according to the first embodiment will be described. The projector according to the present embodiment displays a direction setting menu screen for reversing the movement direction of the lens shift by the remote controller according to a change in the installation posture (installation mode) of the projector.

[0036] figure 1 It is a perspective view showing the projector according to the first embodiment, (a) of the figure shows the front and upper surfaces of the device main body, and (b) of the figure shows the back and the bottom. in addition, figure 2 as well as image 3 It is a side view showing a state that a projector projects an image, figure 2 It is a figure showing the state (standing posture) where the main body of the device is placed on a desk, etc., image 3 It is a figure showing the state (hanging posture) of the apparatus main body being fixed on the ceiling etc.

no. 2 Embodiment approach

[0087] Next, a projector according to the second embodiment will be described.

[0088] The projector 100 according to the second embodiment displays the remote control lens shift direction setting menu screen M2 based on the projector's installation mode and direction inversion information.

[0089] The external appearance and device configuration of the projector 100 according to the second embodiment are the same as those of the projector 1 according to the first embodiment, and therefore description thereof will be omitted. In addition, since the block diagram showing the schematic configuration of the projector 100 according to the second embodiment is the same as that of the projector 1 according to the first embodiment, description thereof will be omitted. In addition, in the second embodiment, the previous setting pattern storage unit 25 in the block diagram may not be present.

[0090] Next, the operation of the projector 100 according to the second embodiment will b...

Abstract

The invention provides a projector capable of changing the direction of the lens shift with good maneuverability and a control method of projector. The projector includes: a lens position control unit which controls a projection position of an image by shifting a projection lens; a signal receiving unit which receives a position control start signal to start position control and a lens shift signal from a remote controller; a direction conversion memory unit which stores direction conversion information corresponding to the lens shift signal as information for performing a predetermined conversion of the shift direction of the projection lens; a shift direction converting unit which converts the shift direction of the projection lens based on the direction conversion information; a menu display unit which displays a direction conversion menu screen through which the direction conversion information is inputted; and a control unit which allows the menu display unit to display the direction conversion menu screen when a predetermined condition is satisfied at the time of reception of the position control start signal.

Description

technical field [0001] The invention relates to a projector and a control method of the projector. Background technique [0002] Projectors are used in various places such as companies, event sites, schools, and homes. As the installation posture of the projector in these places, there is a posture of setting it on a table or the like to project onto a screen (hereinafter referred to as a normal posture), and there is also a posture of turning the projector upside down and using it on a high place such as a ceiling. Fix it with a jig for fixing and fix it in a hanging manner to make it projected (hereinafter referred to as a hanging posture). [0003] In addition, some projectors also have a lens shift (lens position adjustment) function, that is, a function of adjusting the projection position of an image by moving the projection lens. This lens shift function can be operated by a remote controller attached to the projector. [0004] Conventionally, when the installation...
