Title: Method and apparatus of controling bit rate in image encoding
Inventor: SHIN DAE KYU
IPC: H04N7/24
Filed: 2005-07-25
Abstract: A method and an apparatus for controlling a bit rate in image coding are provided to process a partial region of an image as high image quality when the image is encoded. A high image quality region setting/judging unit classifies the entire picture into a high image quality region and a low image quality region, and assigns more bits than the low image quality region to the high image quality region(351,353). If a region to be currently encoded is included in the high image quality region(355), the high image quality region setting/judging unit performs a coding process by using a comparison value of a bit assigned to the region to be currently encoded and a general quantization coefficient determined according to a quantization coefficient of a correspondence region of a frame previously encoded(359). If the region to be currently encoded, included in the low image quality region, is a region adjacent to the high image quality region(357,361), the high image quality region setting/judging unit compares the general quantization coefficient with the predetermined maximum quantization coefficient on the basis of a quantization coefficient of the high image quality region of the frame to be previously encoded, and determines the last quantization coefficient(365). If the region to be currently encoded is not the region adjacent to the high image quality region, the high image quality region setting/judging unit determines a quantization coefficient by referring to a quantization coefficient of a region previously encoded in the same frame, and performs a coding process(369).
