Client device for displaying images of a controllable camera, method, computer program and monitoring system comprising said client device

A method for displaying camera images on a screen with a client device, the method comprising:

• displaying a first image representation on the screen, the first image representation showing an actual image in an actual visual range of a camera,
• selecting a desired visual range of the camera,
• displaying a second image representation on the screen, the second image representation being an intermediate camera image captured during a movement of the controllable camera, the intermediate camera image including at least some portion of the actual image fit correctly in terms of position and size within the desired visual range and a pixel-free region, and
• displaying an additional image representation on the screen, the additional image representation showing a desired image of the desired visual range fit correctly in terms of position and size within the desired visual range,
• wherein the pixel-free region is a blank region representing a region of the desired visual range in which the actual image does not have image information congruent to the desired visual range,
• wherein the pixel-free region is reduced in size as the desired visual range is filled in as updated image information congruent to the desired visual range is loaded from the camera, and
• wherein the communications device receives (a) the actual image together with metadata associated with the actual image, (b) the desired image together with metadata associated with the desired image, or (c) both the actual image together with metadata associated with the actual image and the desired image together with metadata associated with the desired image, wherein the metadata facilitate an integration of the camera images into a common reference system.

A non-transitory machine-readable storage medium having a computer program stored thereon having program code for carrying out, on a computer connected to a screen, all of the steps of:

• displaying a first image representation on the screen, the first image representation showing an actual image in an actual visual range of a camera,
• selecting a desired visual range of the camera,
• displaying a second image representation on the screen, the second image representation being an intermediate camera image captured during a movement of the controllable camera, the intermediate camera image including at least some portion of the actual image fit correctly in terms of position and size within the desired visual range and a pixel-free region, and
• displaying an additional image representation on the screen, the additional image representation showing a desired image of the desired visual range fit correctly in terms of position and size within the desired visual range,
• wherein the pixel-free region is a blank region representing a region of the desired visual range in which the actual image does not have image information congruent to the desired visual range,
• wherein the pixel-free region is reduced in size as the desired visual range is filled in as updated image information congruent to the desired visual range is loaded from the camera, and
• wherein the communications device receives (a) the actual image together with metadata associated with the actual image, (b) the desired image together with metadata associated with the desired image, or (c) both the actual image together with metadata associated with the actual image and the desired image together with metadata associated with the desired image, wherein the metadata facilitate an integration of the camera images into a common reference system.
