Title: Optical pickup device
Inventor: KITABAYASHI JUNICHI
IPC: G11B11/105
Filed: 1990-07-12
Abstract: PURPOSE:To obtain a focus error signal or a track error signal in a high sensitivity condition by installing a photodetector at a position close to the opposite side of the exiting end surface of a laser light source for detecting a signal. CONSTITUTION:The surface of an optical disk 10 and the exiting end surfaces of the laser light sources 19, 20 for detecting the signal constitute a recursive optical system in confocal position relation. Accordingly, now, if an interval between the surface of the optical disk 10 and an objective lens 9 is dislocated, difference comes to be caused in return light from the optical disk 10 to each exiting end surface of the laser light sources 19, 20 for detecting the signal. This difference of the return light is expanded by the amplifying action of the height of the signal detecting laser light sources 19, 20, and is detected by the photodetectors 21, 22 located at the opposite sides of the existing end surfaces. Then, the difference of the quantities of light detected by these two photodetectors 21, 22 is obtained. Thus, the highly sensitive detection of the focus error signal can be executed, and the track error signal too can be detected in the high sensitivity condition.

Abstract: PURPOSE:To prevent the omission and error of a color filter selection by installing a color/temperature detecting means, a discriminating means for discriminating an optimum color filter in terms of the output of this color/ temperature detecting means and an informing means which informs a photographer of this optimum color filter. CONSTITUTION:A light which passes through a blue filter 5 for passing blue light and a red filter 6 for passing red light is received by photodiodes 7 and 7, and an output is inputted directly to the positive input of two comparators 8 and 8 and separately to the negative input of said comparators by means of resistors R and R2, and R3 and R4. When the blue input is sufficiently larger than the red input, an LED11 is lighted, and when the red input is sufficiently larger than the blue input, an LED10 is lighted, while an LED12 is lighted through an NAND gate 9 when the red and blue inputs are almost equal. Accordingly, the discrimination whether the surrounding light is bluish, reddish or nither of them is indicated by the LED10, 11 and 12, thereby making possible the selection of color filters.
