Title: Detector for image density unevenness
Inventor: SAITO JUNICHI
IPC: G06T7/00
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To prevent a wrong detection of superimposed noises by deciding an uneven pixel when the difference of luminance value between a pixel and its adjacent one is kept between the upper and lower limit levels which are previously set for every pixel and detecting a set of uneven pixels as the image. SOLUTION: The image data are stored in an image data array D (S1), a uneven map array E of the same size as the array D is produced (S2) and all elements are reset at 0 (S3). The minimum luminance difference value DMIN, the maximum luminance difference value DMAX and the minimum number LMIN of continuous dots are inputted (S4). Then, the image data array which is obtained by an image pickup means are scanned from a pixel of coordinates (1, 1) through a pixel of (XMAX, YMAX) according to the image size of the image data array. An attentional pixel is regarded as an uneven area and a set of uneven pixels is detected as the image density unevenness (S14) when even one of luminance differences DX-, DX+, DY- and DY+ is larger than the value DMIN and also smaller than the value DMAX (S8-S13).

Title: Crystal type gas manometer
Inventor: TAMURA FUJIO
IPC: G01L9/00
Filed: 1985-12-02
Abstract: PURPOSE:To lock a PLL circuit by sweeping the oscillation frequency of a variable frequency oscillator with a start switch ON and tuning it to the resonance frequency of a crystal resonator. CONSTITUTION:When a power switch is turned on, the oscillation frequency fosc of the variable frequency oscillator 1 decreases gradually and becomes equal to the resonance frequency fo of the crystal resonator eventually. When the varying speed of this frequency almost matches with the response time of the crystal resonator 5, a resonance current is conducted through the crystal resonator 5 and is amplified by an amplifier 2 to lock the variable frequency oscillator 1 through a phase comparator 3 and a low-pass filter 4. The subsequent oscillation frequency fosc of the variable frequency oscillator 1 is equal to fo. Thus, the PLL circuit is locked at the resonance frequency of the crystal resonator 5.
