Abstract:
PROBLEM TO BE SOLVED: To perform a highly accurate focusing operation in the technology of automatically focusing a lens. SOLUTION: When a video camera 10 is shipped from a factory, a microcomputer 400 reciprocates a focus lens 150, obtains a value at which an AF evaluation value peaks in each moving direction, and also obtains the position of the focus lens 150 at the peak. When the video camera 10 is initialized, the microcomputer 400 detects the original position of the focus lens 150 during the forward movement and backward movement, and obtains an amount of displacement of the position. Based on each parameter thus obtained, the microcomputer 400 calculates a correction value during an auto-focus processing. Based on the correction value, the microcomputer 400 corrects the peak value of the AF evaluation value and the peak position of the focus lens 150, and determines whether the focus lens 150 has focused.

Abstract:
PROBLEM TO BE SOLVED: To provide a data presentation device with improved operability that can prevent view of viewers to a presenter from being blocked as much as possible when not in use. SOLUTION: Since an imaging camera body part 52 is constituted by mounting an imaging camera body to one end of an imaging camera 17 and an operation section 51 is mounted with a zoom dial 58 or the like for adjusting the imaging camera at the other end of the imaging camera 17, it is possible to implement operations such as focusing and zooming of the imaging camera at the end of the imaging camera 17 so as to improve the operability. Further, since a section of a rotary bearing 55 of a rotary shaft 16 of a support 13 is formed at a base end of the operation section 51, the distance from one end of the imaging camera body 52 is longer than the distance from the other end mounted with the operation section 51, and the view of the viewers to the presenter is prevented from being blocked as much as possible by revolving the imaging camera 17 in a horizontal posture when not in use so that the imaging camera 17 has a vertical posture wherein the imaging camera body 52 is downwardly located.

PROBLEM TO BE SOLVED: To provide a setting method that facilitates the setting of a serial interface circuit between each device to be controlled and a controller and the setting of response control data. SOLUTION: Application software is used to select and set the serial interface circuit to eliminate the necessity of an on/off switch that is needed for the setting of switching. The selection and setting of the serial interface circuit about the device to be controlled that is connected to a controller 2 can be managed by a database 26 to avoid setting errors. Since transmit/receive data and parameter information can be set by means of setting software, even a person without the ability to create programs can customize the response control of the device to be controlled that is connected to the controller.

Abstract:
PROBLEM TO BE SOLVED: To provide a data presentation apparatus capable of suitably carrying out a presentation. SOLUTION: Upon the receipt of selection of a pointing marker PM from an OSD, the data presentation apparatus displays the pointing marker PM at the same position as a position of a mouse cursor MC. When the data presentation apparatus detects a left click of a mouse at an optional position on a screen, the data presentation apparatus fixedly locates the pointing marker. The pointing marker once located can freely be moved when a left click is detected on the pointing marker. Since the pointing marker can point out an optional position on an image even when the mouse cursor MC is moved, the data presentation apparatus can suitably carry out the presentation.

Abstract:
PROBLEM TO BE SOLVED: To provide a low cost mechanical cam type zoom lens device with which occurrence of focus divergence during a zooming operation caused by manufacturing errors of constituting parts is prevented. SOLUTION: In a focusing condition of a focus lens, judgement is made to judge whether a moving position Z(x) of the zoom lens is included in either one of adjacent set zooming positions Z(k-1) and Z(k) (where k=1 to 6) of a plurality of set zooming positions Z(0) to Z(6) and reference correction values Δ(k-1) and Δ(k) are read from a memory at the set zooming positions Z(k-1) and Z(k). Then, based on the set zooming positions Z(k-1) and Z(k), the reference correction values Δ(k-1) and Δ(k) and the zoom lens position Z(x), a focusing adjustment correction value Δ(x) of the focus lens is computed by conducting linear interpolation between the set zooming positions Z(k-1) and Z(k) where the position is included.

Abstract:
PROBLEM TO BE SOLVED: To provide a magnification reading machine that improves convenience at the time of writing on a document or the like in particular by improving user-friendliness for a vertically written sentence as well as a horizontally written sentence. SOLUTION: In the case of a horizontally written sentence, an image pickup camera 28 is held at one between both right and left side parts 21a and 21b of a base 2, the base 2 is shifted horizontally to scan the sentence, and magnified characters to be displayed on the display screen 15 of an LCD monitor 14. A roller 7 in an anteroposterior direction provided on the bottom surface of the base 2 makes movement in the anteroposterior direction smooth. When a right-handed person performs writing, the image pickup camera 28 is held at the right side of the base 2, and a left-handed person performs writing, the image pickup camera 28 is held at the left side of the base 2. In the case of a vertically written sentence, the base 2 is turned to the right or left to scan the vertically written sentence. The base 2 is respectively turned such that the image pickup camera 28 is located at the right side when the right-handed person performs writing and that the image pickup camera 28 is located at the left side when the left-handed person performs writing.

PROBLEM TO BE SOLVED: To provide a reflection type infrared cut filter realizing the improvement of manufacture efficiency by saving time and cost required for manufacture, and to provide its manufacturing method. SOLUTION: In the infrared cut filter 10 constituted by forming multilayer film 200 consisting of ≥16 and ≤32 layers obtained by alternately laminating a plurality of high refractive thin films 210 and a plurality of low refractive thin films 220 on a glass base plate 100, a 1st layer from the glass base plate 100 side is the high refractive thin film 210 and a final layer is the low refractive thin film 220. The film formation is performed so that the 1st and the 2nd layers may have ≥(λ/4) optical film thickness, a 3rd layer or a specified layer may have ≤(λ/4) optical film thickness, a layer between the specified layer and the final layer may have ≥(λ/4) optical film thickness and the final layer may have ≤(λ/4) optical film thickness when design wavelength is defined as λ.
