Abstract
An image driving device includes a determining unit, and image processing unit, and a memory. The determining unit determines whether an input image is a moving image or a still image, and may be synchronized with an internal clock different from an external clock. The image processing unit may image-process at least one frame but less than all frames of the input image when the input image is determined to be a still image. The image processing unit may output the at least one image-processed frame as first image data, and the memory may store the first image data.
Claims20
An image driving device, comprising:
- an analyzer to output a value indicative of whether an input image is a moving image or a still image, the analyzer to be synchronized with an internal clock different from an external clock;
- an image processor to receive the input image and perform image-processing for compensating image quality of the input image, the image processor to receive the value and to perform the image-processing on different numbers of frames based on whether the value indicates the input image is a still image or a moving image, wherein the image processor is to perform the image-processing for compensating image quality on at least one frame but less than all frames of the input image to generate a first image data if the value indicates the input image is a still image, and the image processor is to perform the image-processing for compensating image quality on all frames of the input image to generate a second image data, if the value indicates the input image is a moving image;
- and
- a memory to store the first image data received from the image processor if the value indicates the input image is a still image.
1 more element
An image driving device, comprising:
- an interface to receive an input image from outside the image driving device;
- an analyzer to output a value indicative of whether an input image is a moving image or a still image;
- an image processor to receive the input image and perform image-processing for compensating image quality of the input image, the image processor to receive the value and to perform the image-processing on a different number of frames based on whether the value indicates that the input image is a moving image or still image, wherein the image processor is to generate first image-processed frames by performing the image-processing for compensating image quality on at least one frame but less than all frames of the input image if the value indicates the input image is a still image, and the image processor is to generate second image processed frames by performing the image-processing for compensating image quality on all frames of the input image if the value indicates the input image is a moving image;
- and
- a memory to store the first image-processed frames received from the image processor if the input image is a still image, wherein power consumption to output the input image as output data differs based on whether the input image is a moving image or still image.
2 more elements
An apparatus, comprising:
- an analyzer to output a value indicative of whether input image data corresponds to a moving image or a still image;
- and
- an image processor to receive the input image and perform processing for compensating image quality of the input image, the image processor to receive the value and to perform the processing for compensating image quality on a first number of frames of the input image data when the value indicates that the input image data corresponds to a still image and to perform the processing for compensating image quality on a second number of frames when the value indicates that the input image data corresponds to a moving image, wherein the first number of frames is different from the second number of frames, wherein the image processor is to output the processed first number of frames to a graphic memory if the value indicates that the input image data corresponds to a still image, and wherein the image processor outputs the processed second number of frames without storing the second number of frames in the graphic memory if the value indicates that the input image data corresponds to a moving image.
