An electronic device includes a frequency analyzing circuit and a color difference calculating circuit. The frequency analyzing circuit receives an image signal including information about a subject, may convert the image signal into first color data which are based on a first color domain, converts the first color data into frequency data which are based on a frequency domain, and applies frequency weights corresponding to the frequency data to the first color data to generate processed color data. The color difference calculating circuit calculates color difference values for evaluating a color stain generated by the image signal, based on the processed color data. The frequency weights are selected based on sensitivity information of an observer according to a frequency change of the frequency data.

Methods and systems for managing content items are described. A content item may be separated into components, such as chroma components, luminance components, and audio components. For more efficient management of the content, including for storage and delivery of the content, the separate components may be stored at different locations. For example, chroma components may be stored on a central server, while luminance and audio components are stored at other locations, such as edge servers, or vice versa, to accommodate network efficiency considerations. When content is delivered to a player, two or more separate streams carrying different content components may be delivered to the player.

An image processing device includes a multimedia intellectual property (IP) block which processes image data including a first component and a second component; a memory; and a frame buffer compressor (FBC) which compresses the image data to generate compressed data and stores the compressed data in the memory. The frame buffer compressor includes a logic circuit which controls a compression sequence of the first component and the second component of the image data.
