    Abstract: A display driver circuit, configured to drive a display panel, includes a time recording circuit, a storage circuit, and an output control circuit. The time recording circuit calculates a first time interval between a first vertical synchronous pulse and a second vertical synchronous pulse subsequent to the first vertical synchronous pulse. The storage circuit stores a display data corresponding to the first vertical synchronous pulse when the first vertical synchronous pulse is received by the display driver circuit. The output control circuit is coupled with the time recording circuit and the storage circuit. When the display driver circuit receives the second vertical synchronous pulse, the output control circuit outputs data pieces, generated by dividing the display data, to the display panel. The data pieces are outputted at second time intervals, and each of the second time intervals is positively correlated with the first time interval.

    Abstract: A color translation method and a color translation apparatus adapted to map a data point from a first color space to a second color space are provided. At least four color axes coordinating with a plurality of first reference points and a plurality of second reference points corresponding to the first reference points are used to divide the first color space and second color space into a plurality of first sub-spaces and a plurality of second sub-spaces. A target first sub-space where the data point is located is found, and then a corresponding target second sub-space is also found. According to a positional relationship between the data point and the first reference points which define the target first sub-space, an interpolation operation is applied to the second reference points which define the target second sub-space so as to obtain a mapped point in the second color space.

    Abstract: An image device and an image processing integrated circuit (IC) of the image device are provided. The image device includes a camera module, a display panel, a central processing IC, and an image processing IC. Based on a control of the central processing IC, the image processing IC decides whether to pre-process an output of the camera module and provide a pre-processed result to the central processing IC, or provide the output of the camera module directly to the central processing IC. Based on the control of the central processing IC, the image processing IC decides whether to post-process an output of the central processing IC and provide a post-processed result to the display panel, or provide the output of the central processing IC directly to the display panel.

    Abstract: Artifact reduction method and apparatus, and image processing method and apparatus are provided. The artifact reduction apparatus includes a scaling-down unit, a buffer unit, an artifact detection unit, a scaling-up unit and a filter unit. The scaling-down unit scales down a resolution of a current original image frame to obtain a current low-resolution image frame. The artifact detection unit performs an artifact detection to the current low-resolution image frame to obtain low-resolution weights in accordance with a relation of the current low-resolution image frame and a previous low-resolution image frame provided by the buffer unit. The scaling-up unit scales up a number of the low-resolution weights to obtain a high-resolution weights. By using the high-resolution weights, the filter unit performs an image processing procedure to the current original image frame for reducing artifact of the current original image frame and obtaining an adjusted image frame.
