摘要： PURPOSE:To accurately and surely extract an objective image regardless of fine ruggedness on the boundary by only inputting a rough contour surrounding an extraction objective image area. CONSTITUTION:A rough contour 22 is inputted and is displayed over an original image 12 as shown in (b), and the edge strength and the ease gradient direction edge continuity) or picture elements included in this rough contour line 22 are obtained, and plural picture elements 33 having a continuity shown in (d) are obtained based on the edge gradient direction, and the picture element having the height edge strength (for example, the peak picture element) out of these continuous picture elements 33 is taken as a start point T0 of tracing, and the picture elements having the highest edge strength out of peripheral picture elements of a tracing point Ti is taken as the next tracing point Ti (i=i+1) to repeat tracing, and thus, a narrowed contour line 40 is obtained as shown in (f). Therefore, the accurate narrowed contour line 40 extended along peak picture elements is obtained, and an objective image 12a surrounded with this line 40 is accurately and surely extracted.

摘要： PURPOSE:To bring a linear contour line for picture extraction close to the real contour line of an original picture with a simple operation by correcting the linear contour line by means of the straight line which connects the start point of deviation, the end point, and the point with the maximum deviation. CONSTITUTION:A linear contour line 24 specifies a start point S of deviation, an end point E of deviation, and end point E of deviation, and a point M with the maximum deviation from a part deviated from a real contour line 30 of the original picture, a microprocessor stores position information of each specification point S, E, and M by the storage and display function of the specification position based on the program for storage and display of the specified position stored in a ROM and is displayed on the ROM. Then, the microprocessor rewrites information on SE of the linear contour line 24 of the contour line storage part by means of information of straight line 24a which connects the three points S, E, and M by the correction program and replaces the SE of the linear contour line 24 at the correction on the CRT display.

摘要： PURPOSE:To simplify key operations by reducing the number of times for press ing keys required for menu selection when the maximum program number of a menu screen is over two digits. CONSTITUTION:In the menu selecting method for selecting a prescribed program from the menu screen by pressing ten keys by N times (N is an integer of >=1.), a timer starts counting time from the beginning for every time of pressing the ten keys, and when the count value exceeds a set value, it is defined as selection definite time. When the N is 1, the question of 'whether a second key number n2 is inputted within set time or not?' is turned to NO, and a definite frame is displayed on the program of the menu picture corresponding to n1. When the N is 2, the question of 'whether the second key number n2 is inputted within the set time or not?' is turned to YES, and the definite frame is displayed on the program of the menu screen corresponding to 10Xn1+n2. Subsequently, the same processing is executed. Thus, when the key number is '1'-'9', the selection is defined by pressing the key once, and when the key number is '10'-'99', the selection is defined by pressing the key twice.

CONSTITUTION:A label (b) is imparted to the boundary line of a boundary line image, a label (c) is imparted outside the boundary line, a first number is given to a picture element corresponding to the designated point designated within either one of an internal area and an external area and the label is changed from (c) to (a). In a first step, an object picture element having a label (c) among picture elements connecting the vicinity of the first numbered picture element is given with a consecutive number and its label is changed from (c) to (a). In a second and succeeding steps to be successively executed, an object picture element having a label (c) among picture elements connecting the vicinity of respective numbered picture elements is given with a number consecutive to a number given in a just be fore step and the label is changed from (c) to (a).

摘要： PURPOSE:To display pictures recorded as three pictures or more scrolling smoothly and continuously without interruption, in a still picture reproducing device. CONSTITUTION:In a still picture reproducing device which enable continuous scrolling by switching a screen, a host computer 2 reads program data (reproducing control command; defined in a HVC guideline) of a floppy disk 24, while, when the device is controlled according to the reproducing control command, a read roll command of the reproducing control command column is detected, also when the roll command (same parameter) is continued, it is converted to a continuous scrolling command (command not defined in the HVC guideline; for example RCU) of exclusive use for the device, and a first and a second picture processors 13, 14 are controlled according to the reproducing control command including this converted command. Then, the first picture processor 13 taking charge of picture effect controls a screen by the continuous scrolling command, while the second picture processor 14 writes in and reads out first to third picture memories 8-10.

摘要： PURPOSE:To make the appearance of a picture excellent when the picture is displayed on a screen by a projection type display device. CONSTITUTION:When a picture by a liquid crystal panel 3 is projected on a screen 5 in this projection type display device, a lenticular lens 7 which enlarges the picture on the screen 5 in a vertical direction is provided between the panel 3 and a projecting lens 4. Thus, in the case that the number of the display picture elements of the picture constituted on the panel 3 is fewer than the total number of the picture elements of the panel 3, a dark part is not made on the screen 5 and the picture can be displayed extending over the whole surface of the screen 5. Thus, the appearance of the picture can be made excellent.

摘要： PURPOSE:To accurately and surely extract an objective image by only designating and inputting a partial area including the boundary of the extraction object. CONSTITUTION:An area 36 including at least one picture element of the boundary of an original picture 12 is designated by the input from a tablet or the like as shown by (b), and the picture element having the highest edge strength is detected from picture elements included in this designated area 36 as shown by (d), and this detected picture element is taken as a start point T0 of tracing to obtain a narrowed line contour 40 by edge tracing which takes the picture element having the highest edge strength or a high edge connectability out of peripheral picture elements as a next tracing point Ti as shown by (e). Therefore, the narrowed line contour 40 accurately traced along peak picture elements is obtained. Picture elements surrounded with this contour 40 are labelled to extract an objective image 12a.
