Abstract: An image processing method and apparatus for processing an image signal using a DSP (digital signal processor), wherein shading correction process, logarithmic transformation process, edge emphasizing process, density adjustment process, binarization process or the like are performed utilizing the DSP and a look-up table outside the DSP. An image signal is inputted in an order of raster scanning, each pixel data of the image signal is set to an input register of the DSP, calculations necessary for shading correction is performed in parallel on the pixel data by a plurality of ALUs in the DSP, and a logarithmic transformation is performed on the calculation results utilizing the look-up table. Further, the logarithmically-transformed signal is inputted to the DSP and set to the input register for an edge emphasizing process which is performed by the plurality of ALUs. The result is inputted again to the look-up table for a density adjustment process and sent to the DSP, then binarized by the DSP and outputted.

Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method for ink-jet recording which shorten a printing time and enable a production cost to be reduced. SOLUTION: Registers 301, 302, 306, 307 for setting a segment where a recording head is driven are set to the same recording head. The registers are preset before the head is moved to form images. The recording head is driven at a plurality of points during one movement thereof, thereby discharging ink. The movement for printing is executed once after a CPU sets the registers, whereby images are formed. A printing time is accordingly shortened. While an ink discharge opening is provided at one point thereby making a main body outline small, the printing time is shortened.

Abstract: PROBLEM TO BE SOLVED: To accurately conduct a recording operation at a low cost according to a position detection signal asynchronously generated by reading a memory in synchronization of an output of a memory control means with an output of a position detecting means, and driving a recording means in response to outputs of an image memory and a record control means. SOLUTION: When a CPU 117 rotates a motor 115, a printer carriage 102 starts moving along an encoder scale 103, and outputs position detection information from an encoder head 104. In this case, control of an effective image section signal generating means 108 by the CPU 117 is conducted asynchronously with control of a motor control means 116, and timing of generating an effective image section signal VE becomes asynchronous with timing of a generating the position detection information from the head. Thus, the asynchronously generated position detection information ENCP is synchronized with a memory operating cycle generated in synchronization with the signal VE by a synchronizing means 111.

Abstract: PURPOSE:To form a picture in which joints do not give unnatural sensation by composing plural film pictures, eliminating overlapped parts of the films and adjusting the color, density and magnification of the joints. CONSTITUTION:A light of a lamp 101 strikes on a film 102 in a projector section to generate an processor picture signal, the outputted optical signal is converted into an analog electric signal by a photoelectric conversion element 104, in which the signal is converted into a digital electric signal and shading, input masking and sharpness processing or the like are applied to picture data by a picture processing section 107. Then a duplicate part detection section 108 detects duplicate part and a picture synthesis section 109 synthesizes pictures while cutting plural duplicate parts to execute processing into one picture. Then a picture processing section 11 at a final stage execute color correction, color conversion and magnification processing or the like to correct a delicate difference of the jointed part and the result is outputted.
