Abstract: A method to simultaneously generate and capture a plurality of blurred images utilizing a camera lens and a plurality of imaging sensors is described. A signal passes through a lens and is then split into a plurality of signal paths of different lengths using a signal splitting device. Since the physical distances between the lens and the plurality of imaging sensors are different, with different signal path lengths, a plurality of uniquely blurred images are captured by the plurality of imaging sensors. Utilizing the plurality of blurred images, computations are performed and blur differences are calculated. A depth map is then determined from the blur differences. With the depth map, a number of applications are possible.

Abstract: Image projection apparatus wherein, a focusing lens is controlled when a shutter is operated so that a contrast signal, obtained when a luminance signal from a camera signal processing circuit is supplied to an auto focusing detection circuit, may become maximum. A laser diode is driven to generate laser beams that are condensed into parallel laser beams by a condenser. These parallel laser beams are applied to a hologram plate and thereby diffracted. The diffracted laser beams interfere with each other, to produce a hologram image with sufficient contrast. Therefore, satisfactory focusing can be made in an auto focus mode of the contrast detection system or in a manual focus mode.

Abstract: An imaging acquisition system that generates a depth map for a picture of a three dimension spatial scene from the estimated blur radius of the picture is described. The system generates an all-in-focus reference picture of the three dimension spatial scene. The system uses the all-in-focus reference picture to generate a two-dimensional scale space representation. The system computes the picture depth map for a finite depth of field using the two-dimensional scale space representation.

Abstract: A fluorescent light flicker characteristic of an XY addressing type image pickup device such as a CMOS image pickup device is accurately detected and reliably and sufficiently reduced through a simple signal processing without using an photosensitive element regardless of the level of a video signal of a subject and the type of a fluorescent lamp. A signal In?(x,y) is an RGB primary color signal or a luminance signal, each containing a flicker component. The signal In?(x,y) is integrated over a duration of time equal to or longer than one horizontal period, and a difference value between the integrated values of adjacent fields is normalized by the average value of the integrated values of three consecutive fields. The normalized difference value gn(y) is discrete Fourier transformed to extract a spectrum thereof, and a flicker coefficient ?n(y) is estimated from the extracted spectrum to calculate In?(x,y)/[1+?n(y)].

Abstract: An image which is seen as a natural feeling can be attained in such a manner that a resolution of a photographed image is kept substantially constant irrespective of any variation in condition of an optical system such as an iris diaphragm diameter and a zoom position. For example, in the case that it is adapted for an iris diaphragm diameter, an MTF corresponding to a variation of an iris diaphragm diameter is measured (FIG. 6A) and then a gain of an output of an aperture control circuit capable of canceling a reduction of high frequency component of the image signal corresponding to the measured MTF (FIG. 6B). Then, an iris diaphragm diameter varied during a photographing operation is detected, a gain set in response to the detected iris diaphragm diameter is applied to the aperture control circuit, thereby a control is carried out such that an amplitude of the high frequency component of the brightness signal (FIG. 6C) being kept substantially constant without having any relation with the iris diaphragm.

Abstract: An automatic focus control method and apparatus are capable of correctly controlling the focus even when an object having a high contrast enters or leaves goes out from a distance measurement frame during the focusing operation. A control microcomputer monitors the detecting position of the focusing signal generated by an automatic focus detection circuit. If the control microcomputer concludes that the detecting position of the focusing signal is in a peripheral area of the distance measurement frame, the control microcomputer outputs a distance measurement frame control signal to change the location or the size of the distance measurement frame so that an object having a high contrast no longer either enters or goes out from the distance measurement frame.
