A method is provided for correcting lightness of an image using a multiscale retinex. Lightness of a subject pixel of an original image is corrected using a convolution operation of a surround function and surround pixels with respect to the subject pixel of the original image, and the convolution operation is performed over a plurality of scales. The surround function has a simplified model such that a value of the surround function is changed in a stepwise way along two axes orthogonal to each other.

A method for correcting lightness of an image includes the steps of: calculating a first scale and a second scale based on an image scale of an original image from image information of the original image; multiscale retinex processing the original image with respect to the first scale and the second scale; and synthesizing a result of the multiscale retinex processing with the image information of the original image.

[Problem to be Solved] To suppress problems due to a flow of a primary coolant while easily distributing a flow rate of the primary coolant to fuel assemblies.[Solution] A pressure-loss adjusting member 60 includes: a pressure-loss adjusting hole 62 that can cause light water to pass therethrough in a state with a pressure-loss being increased more than that of when light water flowing around the fuel assembly passes through only a core support plate flow hole formed in a lower core support plate; and a core support plate engaging unit 70 that can be engaged with the lower core support plate by being inserted into the core support plate flow hole. Accordingly, the flow rate of light water flowing toward the fuel assembly can be reduced by arranging the pressure-loss adjusting member 60 between a lower nozzle of a fuel assembly having a small pressure-loss and the lower core support plate, and rattling or the like of the pressure-loss adjusting member 60 can be suppressed by engaging the core support plate engaging unit 70 with the lower core support plate. As a result, problems due to the flow of light water can be suppressed, while easily distributing the flow rate of light water to the fuel assemblies.

A computer device includes a processor for processing an object code containing a plurality of instruction words. It further includes a memory for storing a plurality of pseudoinstruction words respectively corresponding to the plurality of instruction words. Preferably, the number of bits of each of the plurality of pseudoinstruction words is less than that of each of the plurality of instruction words. Finally, the computer device includes an instruction word converter for converting the pseudoinstruction word read out from the memory into an instruction word of the object code, and for outputting the instruction word obtained by the conversion to the processor.

A character display apparatus with an attribute management unit for storing an attribute of a used font, a raster image storage unit for storing a raster image of the used font, and an image position management unit for storing a storage position of each raster image in the raster image storage unit in correspondence with each attribute of the attribute management unit. The character display apparatus also includes a judgment unit for judging whether a raster image of a character to be displayed is stored in the raster image storage unit or not, by referring to the attribute management unit and the image position management unit. The character display apparatus is further provided with a display unit for displaying an image of the character by use of the raster image in the raster image storage unit, in case that the raster image is stored therein.

A vehicle behavior analysis system performs an analysis of vehicle operation by displaying behavior data in an organized and analyzed form. A vehicle behavior data collecting unit records information on the vehicle's driving as behavior data and an analysis unit analyzes a recorded content of the vehicle behavior data collecting unit. A recorded data unit obtaining part obtains the recorded data units recorded in a memory of the vehicle behavior data collecting unit and a displaying part displays the content concerning at least a predetermined item among the contents shown by obtained each recorded data unit in a form of a table sectioned for each recorded data units and arranged at a side of the analysis unit, and a risk degree calculated based on the content shown by each recorded data units is contained in the predetermined item displayed by the displaying part.

The high speed semiconductor memory includes at least one memory module and a cache controller. The at least one memory module includes a plurality of memory cells for storing data and a cache memory for storing part of the data stored in the plurality of memory cells, The cache controller includes a hit ratio counter for obtaining an average cache hit ratio and a comparator storing a desired threshold hit value and comparing the average cache hit ratio with the desired threshold value. The cache controller determines whether data corresponding to an input address are stored in the cache memory and allows to readout such data from the cache memory, otherwise controlling the read-out of data from the plurality of memory cells for storage in the cache memory so as to update the contents of the cache memory. A request signal for transferring data from the memory cells to the cache memory is generated when the average cache hit ratio is lower than the desired threshold value. The high speed memory further includes a prediction controller for selecting data to be transferred from the memory cells to the cache memory.
