    摘要: In view of the memory or storage disadvantage inherent in conventional picture data memory systems, a picture data memory system provides a system with simplified memory control which equalizes the amounts of the color and black/white picture element data by reducing the resolution of the color picture element data (a picture element representing an area scanned by at least one CCD element) to one-quarter of the resolution of black/white picture element data. The picture data memory system constitutes memory locations having a bit size in accordance with the resolution of the color picture when reproduced by the color printer. By doing so, the numbers of bits are equal for the picture element data of both the color and black/white pictures, thereby allowing the storing of color and black/white picture element data in the memory that has a storage capacity that is no greater than a memory storing only black/white picture data. This system includes picture memory for storing binary data representing both color gradation data and black/white concentration data of each picture element; a controller for producing either a color or a black/white mode select signal; a scanner for producing either color gradation data or black/white concentration data; a first buffer memory for storing color gradation data; a second buffer memory for storing black/white concentration data; and a selector for selecting data from either the first or the second buffer memory to be written into a specific address of the picture memory means. The number of bits representing color gradation data or black/white concentration data written into each address of the picture memory are set to be equal to each other.

    摘要: A color image reading and recording apparatus comprises three light source corresponding to blue, green and red colors disposed at one side opposite to the side of the original to be read. A CCD image sensor is used to obtain signals corresponding to the blue, green and red components of the original through the sequential lighting up and driving of the three light sources. The CCD image sensor receives light reflected from the original. A memory device is used to store color component signals corresponding to the blue, green and red components. A color converter then converts the color component signals into yellow, magenta, cyan and black. The apparatus further records the colors converted by the color converter onto a recording paper by controlling the recording of the yellow, magenta, cyan and black color images onto the same recording paper. Also, the apparatus records the single color images obtained by combination of specified color component signals stored in the memory device onto individual recording papers.

    摘要: An image reading apparatus for reading a transparent film has a light source, an exchangeable adjusting board corresponding to the transmission factor of the film, an imaging device for receiving and imaging the light passing through the adjusting board and the film, a comparison function for detecting the output of the imaging device and comparing the output of the imaging device with a predetermined output level, a control device for outputting power source control signals in response to the output of the comparison device, and a power source for energizing the light source in response to the power source control signals. Whereby, the adjusting board is imaged before the film is imaged by the imaging device, and in case the light amount of the light source is not adequate for the film, the extent of energizing the light source is adjusted for adequately imaging the film.

    摘要: A method of enlarging or reducing an image at a desired magnification in an image reading and/or recording apparatus. The feature of the present invention resides in first deciding the integral part a and the decimal part d of a value A corresponding to the desired magnification Z, then forming a single readout pixel by averaging a pieces of basic pixels read out from an original, and subsequently using the decimal part d as a correction value for each readout pixel and deleting one basic readout pixel every time the value of the decimal part accumulated with respect to the individual readout pixels exceeds 1, thereby continuously varying the ratio of the reading resolution to the recording density to execute enlargement or reduction of the image at the desired magnification.
