Abstract: An image signal processor includes a line interleaving controller and an image signal processor core. The line interleaving controller receives a plurality of image data lines included in an image frame, generates one or more virtual data lines corresponding to the image frame, and outputs the plurality of image data lines and the virtual data lines sequentially line by line. The image signal processor core includes at least one pipeline circuit. The pipe line circuit includes a plurality of processing modules serially connected to sequentially process data lines received from the line interleaving controller. The line interleaving controller processes one or more end image data lines included in an end portion of the image frame based on the virtual data lines. Interference or collision between channels is reduced or prevented by processing the end image data lines in synchronization with the virtual data lines.

Abstract: An image signal processor, an operating method thereof, and an image processing system are provided. The image processing system includes: a control processor configured to generate and output setting information corresponding to N (where N is an integer of 2 or more) image frames; and an image signal processor configured to perform image processing on the N image frames received from an image sensor based on the setting information, and generate an interrupt signal and transmit the interrupt signal to the control processor based on completion of the image processing performed on the N image frame.

Abstract: A device includes an image sensor configured to generate a first signal corresponding to an image having a first resolution in a first mode, a second signal corresponding to an image having a second resolution higher than the first resolution in a second mode. The image sensor is configured to generate frame information regarding a resolution, the first mode and the second mode respectively determined based on a mode signal. The device further includes a channel allocator configured to allocate the first signal and the second signal to different channels, of a plurality of channels, based on the frame information; and an image signal processor (ISP) comprising the plurality of channels, a first channel configured to process the first signal and a second channel configured to process the second signal. The ISP is configured to post-process image data processed by the plurality of channels.
