Title:
IMAGE PROCESSOR AND IMAGE PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2019139060
Kind Code:
A
Abstract:
To provide an image processor capable of reducing power consumption by stopping an image processing circuit when displaying a still image in which an entire image is subjected to image processing by PSR.SOLUTION: In an image processor, a switching signal generation circuit generates a switching signal for controlling switching of image data selected by first to fourth switching circuits such that input image data are subjected to image processing by a first image processing circuit when displaying a still image corresponding to image data after imaging processing by PSR, image data after image processing are written to a frame buffer by control of a panel self-refresh control circuit, and image data after image processing read from the frame buffer are outputted from the fourth switching circuit or image data after image processing are outputted from the fourth switching circuit via the third switching circuit.SELECTED DRAWING: Figure 1
