  • Publication number: 20190394377
    Abstract: [Object] It is desired to provide a technology capable of appropriately controlling brightness of images by using a simpler structure. [Solving Means] Provided is an information processing device including: a determination unit that determines a range of brightness on a basis of a plurality of pieces of imaging data captured by a plurality of image capturing units; and an exposure control unit that controls exposure values of the plurality of image capturing units on a basis of the range of brightness.

  • Patent number: 6542429
    Abstract: A line memory control method for temporarily writing input image data into a line memory and reading out the image data written in the line memory on a block basis, comprising: a pre-processing step of reducing the data rate of the input image data; a writing step of successively writing the pre-processed image data into a line memory every line by using a first address; and a reading/writing step of reading out the image data on a line basis every block by using a second address different from the first address after said writing step is finished, and writing image data into a read-out block by using the second address.

  • Publication number: 20020006228
    Abstract: A data decoding apparatus having a simple circuit configuration and processing data at a high speed by detecting and deleting a marker code by a simple circuit at a high speed. A marker remover deletes the marker from a data stream containing the input marker and generates a data stream having 32 bits of fixed length comprised by only data. Also, 4 bits of a marker flag indicating a type and a location of a marker are generated and added to each data. The 32 bits of data are input via a buffer RAM to a Huffman decoder, the restart marker is detected from the marker flag, and the decoding is carried out while appropriately resetting the DC component value based on this. At the decoding, processing for deleting the restart marker in the data string becomes unnecessary, thus the decoded data can be successively output. Also, the circuit configuration becomes simple too.
