A video encoding device includes a local decode generation unit for generating a reference image based on a result of encoding of a divided image, a compression unit for compressing the reference image to generate a compressed data, a reference image storage determination unit for determining whether to store the compressed data in a memory, and an inter-prediction unit for performing motion vector search for inter-coding based on a reference image stored in the memory. The reference image storage determination unit sets an allowable data amount used for storing the reference image for each determined area of the moving image data, and determines whether or not to store the compressed data obtained by compressing the reference image in the memory based on the allowable data amount. Inter-prediction unit sets the reference image corresponding to the compressed data stored in the memory as the search range of motion vector search.

Video encoding device, operating methods thereof, and vehicles equipped with a video encoding device

A data processing device includes a data selector circuit that divides a plurality of types of data into another plurality of types of data in accordance with a classification of the data, a plurality of compression circuits that respectively compress the plurality of types of data in parallel with each other in accordance with each of the plurality of types of data, and a data transmission circuit that transmits the plurality of types of compressed data to a terminal.

Data processing device, data processing system and method

Making effective use of an image encoder and an image decoder for processing a color image of a general-purpose standard bit depth, an image transmission device capable of transmitting/receiving a monochrome image of a higher bit depth is configured. An image transmission device includes an image encoder to encode a high bit-depth monochrome image and output encoded data and an image decoder to generate, by decoding the encoded data received via a transmission path, a high bit-depth monochrome image. The image encoder decomposes the input high bit-depth image data into plural bit planes corresponding to color image data of a standard bit depth and encodes the standard bit-depth color image data. The image decoder decodes the color image data of the standard bit depth and synthesizes, from the decoded standard bit-depth color image data, a high bit-depth monochrome image.
