Title: Zone plate
Inventor: HORIKAWA YOSHIAKI
IPC: G02B5/18
Filed: 1995-03-24
Abstract: PURPOSE: To decrease the control requests of a device to a numerical range having significance in actuality by providing a zone plate with plural zone groups consisting of plural zones of a specified zone width and to obtain inexpensive zone plate. CONSTITUTION: This zone plate has the plural zone groups consisting of the plural zones 1, 3, 4 of the specified zone width. The zone plate is provided with the plural zone groups consisting of the specified zones 1, 3, 4 in such a manner. Each zone is provided with a single zone 2 of not constituting the zone group to prevent the radius of the zone boundaries from excessively largely deviating from the theoretical value and adversely affecting wave front aberrations. Then, control accuracy of 10nm, i.e., working accuracy eventually suffices and the formation of the zone plate even by mechanical working is possible as well. This zone plate is effectively applicable to both of a zone plate of an amplitude type to alternately repeat transmission and absorption and a zone plate of a phase type to repeat phase transition with adjacent zone to each other.

Title: White balance adjustment circuit and digital camera using it
Inventor: OKAZAKI SEISHIN
IPC: H04N9/73
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To adjust white balance accurately even when a color of an object is suddenly changed by evaluating the color of the object based on a current gain and a 2nd color information signal. SOLUTION: R and B signals outputted from a signal processing circuit 20 are given to corresponding amplifiers 22, 23, where the signals are multiplied by a multiple of α and of β respectively, and an integration circuit 28 and a CPU 30 integrate R' and B' signals from the amplifiers 22,24. On the other hand, no gain is given to a G signal and the G signal is integrated as it is. Thus, integral values IR', IB', IG are obtained. The CPU 30 divides the integral values IR', IB' with the current gain α, βrespectively to calculate integral values IR, IB of the R and B signals that are not multiplied with the current gain αβ. The CPU 30 controls the gain α β based on the integral values IR, IG and IB calculated in this way.
