摘要： An image processing apparatus or a facsimile apparatus or the like is constructed by an input unit for inputting image data, a data conversion unit for converting density characteristics of image data inputted by the input unit, and an output unit such as ink jet printer, laser beam printer, or the like for outputting the image data at a predetermined resolution. The data conversion unit converts density characteristics so as to almost equalize densities even when a resolution of the image data that is outputted by the output unit differs. The data conversion unit converts the density characteristics of the input image data on the basis of a luminance/density conversion table formed every resolution of the image data that is outputted by the output unit. The resolution of the output image data is higher than the resolution of the input image data.

摘要： In a system using a clock synchronous type synchronous DRAM (SDRAM), when a power supply voltage monitoring circuit informs a timing circuit of a decrease in voltage from a main power supply, the timing circuit outputs a self refresh request signal to a CPU. In response to the self refresh request signal, the CPU outputs a clock enable signal synchronous with the system clock, and a self refresh transfer command signal, which is expressed by a combination of states of memory access control signals, to the SDRAM, so as to start up self refresh of the SDRAM. After the self refresh has been started up, the CPU outputs a clock enable mask signal that masks the clock enable signal to switch a clock enable signal to be supplied to the SDRAM from the clock enable signal output from the CPU to a voltage detection signal of a backup power supply. A reset signal then outputs a reset signal to transfer to backup operation.

摘要： The invention relates to an image processing method and apparatus in which, when a binary image is converted to a higher density and interpolated, more effective conversion patterns are proposed and the interpolation upon conversion to higher density is performed by a simple logic operation without using a pattern memory. One original pixel is subdivided into 2.sup.n portions (where n is an integer) in a main scanning direction and/or 2.sup.m portions (where m is an integer) in a subordinate scanning direction, and a density value (or sub-pixel) of the subdivided pixel of a pixel of interest, which has been subdivided, is decided based upon the density value of the original pixel of interest and density values of pixels peripheral thereto. An angle of inclination of a slanted line which is the object of interpolation processing is detected, and the number of sub-pixels, which undergo a density conversion for interpolation processing, is changed in dependence upon the angle of inclination. Alternatively, the width of a slanted line which is the object of interpolation is detected, and the processing density conversion for interpolation is controlled in dependence upon the width of the slanted line. As a result, it is possible to obtain an image in which contour smoothing of the slanted lines of a character image is performed more effectively, with no missing black lines.

摘要： Disclosed are an image processing method and apparatus for applying spatial filtering processing to n-bit multilevel image data, converting the processing image data to two-level or multilevel image data and converting the resulting image data to data capable of being expressed using high-resolution dots. The filtered image data is subjected to a luminance-to-density conversion and is further converted to two or four levels by a four-level/two-level conversion circuit which makes common use of circuitry for executing both two-level error diffusion processing and four-level error diffusion processing. The four-level/two-level conversion circuit clamps the error produced in four-level conversion processing to the number of significant bits of the error produced at execution of the two-level conversion processing. As a result, a common circuit can be used for both the two-level conversion processing and the four-level conversion processing.
