20090245669 | IMAGE PROCESSOR - An image processor includes an encoding unit encoding inputted data. The encoding unit includes a first processing unit splitting the data into a first partial data in a first digit range on an upper side and a second partial data in a second digit range on a lower side, a second processing unit encoding only the first partial data between the first partial data and the second partial data, and a third processing unit performing correction to set a value of the first partial data at “0”. | 10-01-2009 |
20090245674 | IMAGE PROCESSOR - An image processor includes a quantization unit receiving first data before quantization and outputting second data after quantization, a prediction unit obtaining a difference value between the second data and third data being prediction data and outputting the difference value as fourth data, and an encoding unit encoding the fourth data. The quantization unit includes a first processing unit dividing the first data by a quantization coefficient, so as to obtain fifth data including a fraction as a result of division and a second processing unit rounding up or rounding off the fraction such that a value of the fourth data becomes smaller based on comparison between the third data and the fifth data, so as to obtain the second data. | 10-01-2009 |
20100086223 | IMAGE PROCESSOR - A decoding unit includes a first processing unit including ND decoding units and decoding a group of Normal Data, a second processing unit decoding a group of Flex Bits, and a selector. The ND decoding units perform decoding of the group of Normal Data, stepwise varying a start position of decoding in the data stream, concurrently with decoding of the group of Flex Bits by the second processing unit. The selector selects one ND decoding unit with a start position of decoding being set at a position immediately following an end position of the group of Flex Bits, from the ND decoding units, based on a result of decoding of the group of Flex Bits. | 04-08-2010 |
20100104206 | IMAGE COMPRESSION APPARATUS - An image compression apparatus performs quantization of DC component data, low-pass component data and high-pass component data which are generated by frequency conversion of still image data. An extracting part extracts additional data and coding object data which is to be entropy coded, from quantization data. An entropy coding part performs entropy coding of the coding object data stored in a coding object data memory. An additional data processing part generates a flex bit from the additional data. A pattern information generation part acquires the coding object data directly from the extracting part, to generate pattern information indicating whether the coding object data is zero or not. A bit stream generation part outputs the pattern information, the coding object data and the flex bit in a predetermined order, to output a bit stream. | 04-29-2010 |
20100128999 | IMAGE COMPRESSION APPARATUS - A symbol generation part serially inputs a data string of quantization data. If quantization data of non-zero coefficient is inputted, respective information on an absolute value, a zero run and a sign of the non-zero coefficient are stored in registers. When quantization data of the next non-zero coefficient is inputted, the respective information on the absolute value, the zero run and the sign stored in the registers are updated. At that time, the contents of the registers which have been stored immediately before the input are outputted as symbol data of the immediately preceding non-zero coefficient. | 05-27-2010 |

20120093410 | IMAGE PROCESSING APPARATUS AND METHOD FOR OPERATING IMAGE PROCESSING APPARATUS - An image processing apparatus includes a first storage section and a second storage section, a storage control section, and a computation section. The storage control section sequentially acquires block images obtained as a result of dividing an input image, and stores the block image as a target block image in the first storage section, while storing, in the second storage section, image data of, in a region of the target block image, a region abutting un-inputted block images in the input image, as image data of an abuttal region. The computation section implements a resizing process for changing the size of the target block image by performing an interpolation calculation using image data of the target block image stored in the first storage section and the image data of the abuttal region stored in the second storage section. | 04-19-2012 |
20140169631 | IMAGE RECOGNITION APPARATUS - An image recognition apparatus determines whether an image of a pedestrian is captured in a frame of video data captured by a vehicle mounted camera. A pre-processing unit determines a detection block from within a frame, and cuts out block image data corresponding to the detection block from the frame. Block data with a predetermined size that is smaller than the size of the detection block is created from the block image data. A neuro calculation unit executes neuro calculation on the block data, and calculates an output synapse. A post-processing unit determines whether a pedestrian exists within the detection block on the basis of the output synapse. When a pedestrian is detected, the post-processing unit creates result data, which is obtained by superimposing the detection block within which the pedestrian was detected onto the frame. | 06-19-2014 |
