Abstract: PROBLEM TO BE SOLVED: To provide an fθ lens which can easily be increased in resolution even when the lens consists of one element without providing a slit by specifying the constitution of an aspherical surface type used for designing. SOLUTION: In this scanning optical system which reflects beam light emitted by a light source by a rotating polygon mirror and forms an image on a photosensitive body by scanning, the fθ lens of single-element constitution which is arranged between the polygon mirror and an image formation plane and makes fθ corrections is made aspherical in the vertical scanning direction (X axis) and horizontal scanning direction (Y axis). Further, plural terms determining the respective aspherical surfaces are designed by the aspherical surface type defined with >=8 terms including odd and even terms. This aspherical surface expression is as shown by the equation, where the intersection of the fθ lens and optical axis is the origin, the optical-axis direction a Z axis, the main scanning direction an X axis, and the subscanning direction a Y axis. In the equation, Rx , Ry , K, An , and Bm are arbitrary coefficients. Consequently, optical performance needed for high resolution, specially, a very small spot diameter can easily be obtained even when the fθ lens consists of one element.

Title: Digital television circuit
Inventor: NAKAGAWA MASAKI
IPC: H04N9/78
Filed: 1984-12-14
Abstract: PURPOSE:To prevent deterioration of vertical resolution by providing a comb- form filter and a Y/C separating circuit comprising BPF, and using Y/C separating circuit with the BPF in a signal area where the deterioration of vertical resolution will be introduced if the Y/C separation circuit is employed. CONSTITUTION:If the vertical correlation of the illuminance signal does not exist, a signal of large amplitude is inputted to a coefficient generating circuit 25, and the weighting signal has a large value. Accordingly, the illuminance signal 6 and the chromaticity signal 7 that are largely weighted by the output of the BPF120 are obtained. Therefore, the Y/C separation is obtained with less deterioration of the vertical resolution. On the contrary, if the illuminance signal is correlated vertically, a signal of small amplitude of approximately zero level is inputted to the circuit 25, hence the weighting signal 22 has a large value. Therefore, the signals 6 and 7 that are largely weighted by the output of the bomb-form filter 110 are obtained. Thus the Y/C separation is achieved with less disturbance by crosscolor/dot, and the horizontal resolution is improved.
