no. 1 Embodiment

[0036] Figure 6 It is a block diagram of the first embodiment of the multi-screen image signal display device of the present invention.

[0037] The multiscreen processing device 601 receives a signal 601a including a plurality of image signals, divides the plurality of image signals into a plurality of screens, and converts the plurality of image signals into a signal 601b that can be simultaneously displayed by the image display device 602 .

[0038] On the other hand, according to an instruction from a remote controller, etc., the screen selection device 605 outputs signals 605a, 605b selected from one or a part of a plurality of screens displayed on the image display device 602, and input the screen special display device 603, screen Adjustment device 604 .

[0039] The screen special display unit 603 that receives the signal 605 a outputs a signal 603 a for special display of the selected screen to the multi-screen processing unit 601 .

[0040] Based on the input signal...

no. 2 Embodiment

[0049] Next, an image signal display device according to a second embodiment of the present invention will be described with reference to the drawings.

[0050] Figure 7 It is a block diagram of an image signal display device according to a second embodiment of the present invention (screen division will be described as two screens).

[0051] In the figure, 701 is the first image signal processing device that inputs the first image signal 701a and outputs the luminance signal 701b and the color signal 701c; 703 is the first image signal processing device that inputs the second image signal 703a and outputs the luminance signal 703b and the color signal 703c 2 image signal processing device; 707 is an operation signal judging device that inputs a screen operation signal 707a from a remote controller, etc., and outputs selection signals 707b and 707c corresponding to the operation information; 702 is an input luminance signal 701b, and makes the amplitude of the luminance signa...

no. 3 Embodiment

[0065] Next, an image signal display device according to a third embodiment of the present invention will be described with reference to the drawings.

[0066] Figure 10 is a block diagram of an image signal display device according to a third embodiment of the present invention. In the figure, the structures of the first luminance signal amplitude variable device 1002, the second luminance signal amplitude variable device 1004, the operation signal judging device 1007, and the image display device 1008 are the same as those of the second embodiment, and are the same as those of the second embodiment. The difference is the first image signal processing device 1001 and the second image signal processing device 1003 .

[0067] Figure 12 It is a somewhat detailed block diagram of the image signal processing device 1001 (the second image signal processing device 1003 also has the same configuration). In the figure, 1011 is an A / D converter for converting an input image signal...

Abstract

The present invention relates to a multi-picture image signal display device. The present invention is provided with a picture selection means for selecting a part of a plurality of pictures displayed by the picture display means. The screen is adjusted. Since the specially displayed screen has a mark feature indicating that the screen is being adjusted, misoperation can be reduced to a minimum.

Description

technical field [0001] The present invention relates to a device for displaying various image signals on a plane divided screen, or divided screens displayed in an overlapping state on a display device. In particular, when a user selects a desired screen among a plurality of displayed screens, and performs various screen adjustments such as brightness contrast adjustment, hue, and chroma, the screen selection display that can accurately recognize the screen to be operated currently is performed. image signal display device. Background technique [0002] In recent years, in image display devices, screen division and display of various image signals have been increasing. The complexity of screen operations related to adjustment according to the input signal source, switching screen display, etc. is also increasing. [0003] Therefore, there is an increasing demand from users for an image signal display device of a multi-screen display method with good operability during scre...
