An image processing system includes a joining processing unit configured to perform a joining process to join input images captured by an image capturing device and generate an output image the image capturing device being reflected in each of the input images; and an acceptance unit configured to receive selection of one of a plurality of modes for the joining process. The plurality of modes has a first mode to generate an output image in which at least a part of the image capturing device is reflected, through the joining process; and a second mode to, through the joining process, generate an output image whose area where the image capturing device is reflected is smaller than an area where the image capturing device is reflected in the output image in the first mode or generate an output image in which the image capturing device is not reflected.

Techniques are described for using a smart phone or other mobile device to perform automated operations for generating panorama images of building environments and for subsequently using the generated panorama images in further automated manners. In at least some situations, the generation of a panorama image by a mobile device is based at least in part on automatically acquiring multiple constituent images on the mobile device in multiple directions from an acquisition location and on concurrently combining acquired constituent images on the mobile device, such as in a real-time manner relative to the constituent image capture, to generate a panorama image with 360° of horizontal coverage of the view from that acquisition location. Information about such identified building floor plans may be used in various automated manners, including for controlling navigation of devices (e.g., autonomous vehicles), for display on client devices in corresponding graphical user interfaces, etc.

The luminance atmosphere that the creator intends is excellently reproduced on the receiving end. The transmission video data is obtained by applying a predetermined opto-electrical transfer function to the input video data. The transmission video data is transmitted together with the luminance conversion acceptable range information about a set region in the screen. For example, a transmitting unit transmits a video stream obtained by encoding the transmission video data while inserting the luminance conversion acceptable range information into a layer of the video stream. The receiving end obtains display video data by applying an electro-optical transfer function corresponding to the predetermined opto-electrical transfer function to the transmission video data, and performing a luminance conversion process in each of the set regions independently in accordance with the luminance conversion acceptable range information.

A method for shooting image, applied to an electronic device in which an image capturing device is mounted, includes: receiving a first input from a user; responsive to the first input, acquiring a first image and a second image captured by the image capturing device for a target object, a framing range of the first image being same as a framing range of the second image; and performing synthesis processing on the first image and the second image to generate a target image, the target image including a first object image of the target object in the first image and a second object image of the target object in the second image.

A method for processing and transmitting multimedia signals received from a plurality of channels are provided. The method may include receiving at least two multimedia signals from a plurality of channels, and generating a composite multimedia digital signal by coding the multimedia signals in a frame format. At least one of the multimedia signals may include a video signal. The frame format may include an active zone and a blanking zone, the active zone may be configured to encode at least part of the multimedia signals, and the blanking zone may be configured to encode format information. The method may further include converting at least part of the encoded multimedia signals in the active zone into analog signals to generate a composite multimedia signal. The method may further include transmitting the composite multimedia signal to a receiving device via a transmission medium.

An image processing device is provided. The image processing devices includes an input part configured to input an input image; a cutout part configured to cut out a plurality of image regions from the input image input by the input part; and a luminance change part configured to execute luminance change of each of the image regions cut out by the cutout part.
