Latest Patents
One of Ueno's latest patents is an image coding apparatus that includes an entropy coding unit for outputting code data based on control information for every coding pass. This apparatus features a rate control information extracting unit that judges both the continuation and end of the coding pass based on distortion and code amount calculations. Additionally, it includes a unit for extracting code data up to the coding end pass based on control information. The rate control information extracting unit comprises calculation units for determining distortion and code amounts produced by coding each pass, along with a calculation unit for calculating a slope based on the relationship between distortion and code amount.
Another notable patent involves an encoding and decoding apparatus that enhances encoding efficiency by combining multiple encoding methods. This system utilizes a picture element memory to store picture elements within a predetermined range. A mode determinator selects an encoding mode based on a reference picture element, while the encoding sections predict the value of the encoded picture element and determine the accuracy of the prediction before encoding the value.
