INTRA PREDICTION DEVICE FOR IMAGE |
| 摘要 |
A device for performing intra prediction for an image is disclosed. The disclosed intra prediction device includes: a subtractor configured to perform a subtraction operation on a first reference value and a second reference value of a prediction target pixel; a multiplier configured to perform a multiplication operation on a parameter set for each angular mode and an output value of the subtractor; and an adder configured to perform an addition operation on a product of the first reference value multiplied by a predetermined constant and an output value of the multiplier, where an output value of the adder is a resultant value of intra prediction for the image according to an angular mode. |
