Abstract:
PROBLEM TO BE SOLVED: To measure many image quality elements with high accuracy with a small number of image quality sensors by providing an image quality sensor consisting of a fixed focus lens as an image pickup lens and an image quality measuring means based on an image signal from a color video camera. SOLUTION: A CPU 6 controls a signal generator 12 to display a pattern image at each measuring point on a screen of a measured object 1. Next, the entire pattern image shown on a screen of the object 1 is picked up by a color video camera 2, and the image signal is inputted to an image processing circuit 5. After the signal is converted into a digital image signal in an A/D converter 5A, the digital signal is saved in a frame memory 5B. The CPU 6 operates stored data in the memory 5B, calculates a position of each pattern image and makes a monitor 7 show a measured result. An operator watches a shown result and performs image quality adjustment by manually adjusting an image quality adjusting knob of the object 1, or image quality adjustment of the object 1 is automatically performed in response to the measured result.

PURPOSE: To obtain an apparatus wherein a user can process an image of an object with a simple procedure by acquiring and storing images of the object and extracting pixels whose brightness of red, green and blue of an arbitrary region of interest of a binary-coded image is in a specified range. CONSTITUTION: A CCD camera 2 of an image acquiring means 20 acquires images of an object and stores them in an image memory 14. A processing means 25 comprising a system controller 7, an image processing control CPU 16 and an image processor 15 binary-codes an arbitrary region of interest of the stored image and extracts pixels whose brightness of red, green and blue in the region of interest of the binary-coded image is in a specified range to determine whether or not the image of the object is good. The pixels whose brightness of red, green and blue is in the specified range are extracted and displayed on a display monitor 5. A set processing monitor 4 is provided for a user to select and set these processing contents.

PURPOSE:To improve operability and make the display picture of an analysis result easily visible. CONSTITUTION:On the color display 31 of this video signal analysis display device, an image display window 42 and a numeric display window 43 are displayed. On the image display window 42, an image 52 corresponding to one frame and the waveform 45 of the luminance signal of the designated line of a cursor 44 are displayed.

PROBLEM TO BE SOLVED: To shorten the imaging time, without causing the brightness of projected image acquired by means of an X-ray two-dimensional detector to be lowered. SOLUTION: A synchronization signal is sent from a synchronization signal generating part 26 to the X-ray two-dimensional detector 2 so that a first pulse zone arises for longer pulse widths (periods), at imaging an inspected body 7 (in time of its still standing), while a second pulse zone arises for shorter pulse widths (periods), at rotating the inspected body 7 to control the imaging of projection images by means of the two-dimensional detector 2. Projected images of respective angle phases are imaged by means of the two-dimensional detector 2, to perform the reconstruction calculation of internal structure data from the acquired projected images acquired.
