As the coordinates input mode, there are provided an ordinary input mode and an auto-adjust mode. If a coordinate input command is given in the auto-adjust mode, it is determined whether the coordinates already inputted are present within a small area spaced apart by a predetermined distance from the cursor position. If present in the small, predetermined area, the coordinates already inputted are used as the present input coordinates. If not present in the small, predetermined area, the position coordinates of the cursor are used as the input coordinates.

An image processing apparatus that processes image data consecutively in the column and row directions has an image memory, a reading unit, a temporary memory and an operative unit. The image memory stores image data consecutively in column and row directions on a pixel unit basis. The reading unit reads from the image memory a series of pixels within one column at one row and at least one pixel adjacent to the one row in the column direction. The temporary memory sequentially stores a number of groups of pixels read from the reading unit as is necessary for image processing. The operation unit reads the values of an objective pixel and pixels necessary for a neighborhood operation of the objective pixel from the temporary memory, and subjects the values to a neighborhood operation to determine the output value of the objective pixel.

Image processing method and apparatus therefor

In a multi-window system, a plurality of windows are set on a display screen, and data processed results are displayed independently for each window, first and second windows are set on the display screen. When an operator inputs a series of commands so as to effect data processing on the first window, the data processed results based on the inputted commands are displayed on the first window, whereas the inputted commands are sequentially displayed in addition to already inputted commands on the second window.

Lower resolution video signals (10) having alternating odd fields (12) and even fields (14) are stored in an odd line memory 20A and an even line 20B, respectively. An interpolator 22 interpolates adjacent odd and even lines. A selector 24 cyclically selects odd, even, and interpolated lines in a pre-selected pattern, such as one of the patterns illustrated in FIGS. 1, 7, 8A-F, and 9A-F. By selecting even, odd, and interpolated lines, the number of lines per picture is increased to produce a higher resolution video signal (30).

In order to utilize memo data written by hand for purposes of retrieving a document, the original document image data is stored and, thereafter, a document image data with memo is separately input, the document image data with memo being comprised of the original document image onto which is additionally written memo data by hand. The position of the document image data with memo is then brought into alignment with the original document image data and is correlated to extract only that memo data which has been written by hand. Then the kind of memo is discriminated, the process is effected depending upon the kind of memo, and the memo data is stored in a secondary data file for retrieval. To retrieve the document, the memo data of a plurality of documents is read out from the secondary data file depending upon the kind of memo that is designated, and is displayed as a look-up table. If the operator designates any one of them, the image of the corresponding original document is read out from the original document image file and is displayed.
