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： This invention relates to a coding method, code converting method and apparatus, and image forming apparatus and, more particularly, to a coding method, code converting method and apparatus, and image forming apparatus capable of high-speed conversion data coded by different coding method. When data is converted between different coding methods, e.g., when data encoded by a run-length coding method is re-encoded by a coding method using typical prediction, the data is conventionally temporarily decoded into original data before encoding and then re-encoded. In this invention, data subjected to coding such as MH, MR, or MMR as run-length coding is decoded into run-length information as intermediate data, and typical prediction is performed in this state. This increases the speed of conversion from run-length coded data to coded data using typical prediction.

摘要： A printer which records an image on a cut paper sheet must normally assure a margin region at the trailing end side of a record paper sheet in terms of the mechanism of the printer. Conventionally, the margin has a considerably large size. However, this invention aims at reducing the margin size as much as possible and increasing the image record region as much as possible.When a printer of this invention is used in a facsimile apparatus, a problem experienced with a conventional printer, which has a narrow image record region on a record paper sheet, can be prevented. Conventionally, when an image is recorded on a record paper sheet having the same size as that of a received original, the received image is determined as an elongated original image and is divisionally recorded on two record paper sheets, or is recorded on a record paper sheet larger than the received original. This invention prevents this problem.

摘要： At the encoding side, a sum of code lengths of a block is calculated and stored in a memory for each of block lines (stripes); and at the decoding side, when decoding of one block is completed, a head address of a code in the next block is calculated utilizing a sum of an amount of codes utilized for the decoding operation and code lengths for each of the stripes. The rotation process of an image utilizing encoded data is performed in accordance with the head address. Further, at the encoding side, colors of pixels in a predetermined block is determined, and encoding operation is performed block by block for only those blocks including pixels of different colors. At the decoding side, an address of block data for sequentially constructing a rotated image is controlled to decode the pixels in the block, and finally the rotation process is performed on the pixels in the block in accordance with the color of the pixels.

摘要： An image forming apparatus is provided which is capable of immediately performing a recording operation in the case where the apparatus is restored to the operation state from the waiting state. The image forming apparatus has an MPU for performing switching between a normal operation mode, in which the apparatus is operated with normal electric power, and a low power consumption operation mode, in which the apparatus is operated with a low power consumption which is smaller than the normal electric power, so as to reduce electric power consumption. When the MPU switches the mode of the apparatus from the low power consumption operation mode to the normal operation mode, an initial-rotation inhibition signal for inhibiting initial rotation of a motor is generated. In response to the initial-rotation inhibition signal, the initial rotation of the motor is inhibited.
