Abstract

An image signal processor and a device including the image signal processor are provided. An image signal processor may be provided, including: a first data processing circuit; a second data processing circuit; a multiplexing control circuit configured to convert the first line data included in the first frame data into and the second row data included in the second frame data are sent to the first data processing circuit. The multiplexing control circuit may also be configured to send a switching control signal to the first data processing circuit, wherein the switching control signal indicates whether the current row data to be sent to the first data processing circuit is the first row data or the second row data .

Description

[0001] This application claims priority to Korean Patent Application No. 10-2015-0025390 filed with the Korean Intellectual Property Office on February 23, 2015, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] Example embodiments relate to image signal processors, and more particularly, example embodiments relate to image signal processors performing time division multiplexing on images in units of line data and / or devices including the image signal processors. Background technique [0003] According to conventional technology, a single image signal processor can process multiple input images by performing time-division multiplexing using an external frame memory. When the image signal processor performs image signal processing on an input image using an external frame memory in a time-division multiplexing mode, the image signal processor can perform multiplexing in units of frame data. Therefore, the image signal proces...
