摘要： Correlation values in the vertical direction, horizontal direction and two diagonal directions are obtained in a pixel signal of RGB Bayer pattern. The correlation values are calculated using G signals. Between a first pair of the vertical and horizontal directions and a second pair of the two diagonal directions, one pair having a greater correlation difference is selected. Then, a direction having a stronger correlation is selected in the selected pair having a greater correlation difference, and pixel interpolation is performed in the selected direction. Alternatively, pixel interpolation is performed following assignment of weights in two directions of the selected pair having a greater correlation difference in accordance with the proportion of their correlations.

摘要： A rate control unit performs data truncation on a code sequence having been sorted and bit shifted as shown in FIG. 10 so that a desired noise reduction effect is achieved. The data truncation occurs in sequence from the rightmost bit. For example, in FIG. 10, data is truncated from data of bit 0 in a subband VHL4 downwardly in sequence through data of bit 0 in a subband YHH5, and so on. If the desired noise reduction effect can be achieved by truncation of up to bit data in the subband YHH1, data in those subbands in a dotted area in FIG. 10 will be truncated. If the desired noise reduction effect cannot be achieved by truncation of up to bit data in the subband YHH1, data will then be truncated from data of bit 0 in a subband VLL4 downwardly in sequence.

摘要翻译： 速率控制单元对已经排序和位移的代码序列执行数据截断，如图5所示。 使得实现期望的降噪效果。 数据截断从最右边的位开始顺序发生。 例如， 如图10所示，通过子带YHH 5中的位0的数据，通过子带VHL 4中的位0的数据从数据中截取数据，依此类推。 如果可以通过截断子带YHH 1中的最高位数据来实现所需的降噪效果，则图2中虚线区域中的那些子带中的数据可以被实现。 10将被截断。 如果通过截断子带YHH 1中的最多位数据不能实现期望的降噪效果，则数据将从子带VLL 4中的位0的数据顺序向下截断。

摘要： The present invention provides a memory device of a type that outputs a ready signal to the outside, and that is capable of achieving an enhanced data transfer rate and a uniform latency time. A memory device according to the present invention includes a ready signal sending portion, and the ready signal sending portion monitors a memory portion to detect the memory portion becoming ready for reading or writing of specified data. The ready signal sending portion generates a first ready signal that changes from a busy state to a ready state after the detection and an enabling signal that changes from a disable state to an enable state on the basis of a preset ready generating timing value. When the first ready signal is in the ready state and the enabling signal is in the enable state, the ready signal sending portion sends to the outside a second ready signal that is in a ready state.

摘要： A file management information area of a memory includes a FAT and a replacement information table. In the FAT, chain information on a file is recorded and in the replacement information table, replacement information of a defective area is recorded. In order to read out the file, a file system reads out the FAT and the replacement information table to generate indexes of the file and stores the indexes to an index buffer. In a memory controller, an address part of a read command is sequentially replaced with indexes stored in the index buffer and page-replaced read commands are continuously transferred to the memory.

摘要： A similar-image detecting part detects similar image regions similar to one another in a plurality of frame images captured by rolling shutter type exposure. A displacement-vector detecting part detects a displacement vector of each of the similar image regions with respect to a reference position in each of the plurality of frame images. An average calculating part calculates an average of displacement vectors in the plurality of frame images. A correcting part shifts a similar image region in one of the plurality of frame images such that the displacement vector of the similar image region becomes the average calculated by the average calculating part.
