Claim Text:
1. A semiconductor integrated circuit including a video encoder comprising a motion prediction unit, a motion compensation unit, a subtraction unit, a discrete cosine transform unit, a quantization unit, an inverse quantization unit, an inverse discrete cosine transform unit, and an addition unit, wherein: the motion prediction unit generates, in response to a video signal from a camera, a motion vector from the video signal, and the motion prediction unit supplies the motion vector to one input of the motion compensation unit so that, the video signal from the camera can be supplied to one input of the subtraction unit, an output of the subtraction unit can be supplied to an input of the discrete cosine transform unit, an output of the discrete cosine transform unit can be supplied to an input of the quantization unit, an output of the quantization unit can be supplied to an input of the inverse quantization unit, an output of the inverse quantization unit can be supplied to an input of the inverse discrete cosine transform unit, an output of the inverse discrete cosine transform unit can be supplied to one input of the addition unit, a reference image of an output of the addition unit can be supplied to the other input of the motion compensation unit, and a motion compensation prediction signal of an output of the motion compensation unit can be supplied to the other input of the subtraction unit and the other input of the addition unit; and the video encoder divides the video signal from the camera into a plurality of partial images including the central part of the image and the peripheral part of the image according to the distance from the center of the image, and processes the partial images, the video encoder further comprises a pixel processing unit connected between the output of the addition unit and the other input of the motion compensation unit, the pixel processing unit coordinate-transforms coordinates of a pixel included in the central part of the image in the reference image of the output of the addition unit into coordinates of the peripheral part of the image, and the pixel processing unit performs a process of enlarging an object of a subject included in the central part of the image on a pixel-by-pixel basis when performing the coordinate transform, wherein the pixel processing unit responds to speed information to provide compression of the image.
