摘要： PURPOSE:To provide an image formed by a photographing system with desired filter effect by eccentrically driving a correcting optical system which is a part of the photographing system during exposing a photosensitive surface based on amplitude frequency signals inputted from the outside. CONSTITUTION:Driving parts 58a and 58b drive the correcting optical system 58 eccentrically from an optical axis, for example, for a prescribed period of exposing the photosensitive surface 59, based on the amplitude frequency signals 11a and 11b inputted from an outside inputting means. These amplitude frequency signals 11a and 11b generally have a far smaller amplitude than an optical axis eccentric driving amplitude generated by the correcting optical system 58 when it corrects an image blurred by unsteady holding of the camera main body 52. Besides, the phases of the amplitude frequency signals 11a and 11b are deviated by an angle of 90 deg.. Their blur is quite small and roughly circular, compared with the image blurring quantity due to unsteady holding of camera is provided to an image formed by the photographing system on the photosensitive surface 59. Thus, for example, soft effect is provided on the image.

摘要： PURPOSE:To correct the variation of light quantity and shading at the time of recording an image by arranging a sensor on the back side of a photosensitive recording medium and detecting recording light transmitted through the photosensitive recording medium. CONSTITUTION:The title recorder is provided with an a-Si area sensor 8 for detecting the recording light, a reference table 13 recording light reference value by setting an image data value as an address and it performs recording while comparing the recording light detected by the sensor 8 at the time of recording the image with the recording light reference value referred on a reference table 13 from recorded image data 11. And the sensor 8 is arranged on the back side of the photosensitive recording medium 7. Since a part of recording light transmitted through the photosensitive recording medium 7 is detected and feedback is performed to said light, the feedback can be performed to the variation of the light quantity of a CRT 1 where recording is being performed. Thus, the sensor 8 does not have shading characteristic, so that the influence of the shading of an optical system can be cancelled by performing the feedback.

摘要： PURPOSE:To obtain the earlier stability of integrated output by controlling such that the time constant of an integrator is changed. CONSTITUTION:A time constant modification control circuit integrates angular velocity signals from the integrator 6 into angular signals with the aid of an integrator 10. An absolute value circuit 9 issues output in response to absolute values of the angular signals, and a comparator 7 compares the output from the absolute value circuit 9 with that from a chopping wave oscillator 8. On/off pulse signals of prescribed duty ratio imparted in such a way are input to the integrator 6 from a signal line 22, and they are regarded as on/off signals for a switch 20 to modify the time constant. Ultimately control is performed to modify the output characteristics of the integrator 6. Thus, the integrator can detect vibration speedily and precisely at all times.

摘要： PURPOSE:To eliminate the malfunction of AF control by inhibiting the concurrent operation of one means out of an image detecting means and a centering means when either of them is in operation. CONSTITUTION:A linking control means inhibits an image forming system 4 from being moved by the centering means when a photoelectric transfer means 14 being an image detecting means is in operation, or inhibits the photoelectric transfer means 14 from operating while the image forming system 14 is moved by the centering means. Therefore, the range-finding operation of an AF device is performed unless an image blur preventing device is centering. Thus, the AF device never fails in range finding, and malfunction due to erroneous range finding never occurs.

摘要： PURPOSE:To accomplish speedy photographing operation and to eliminate the useless consumption of power by taking advantage of camera posture as information for switching a power supply requiring mode and a power saving mode. CONSTITUTION:A conduction control means stops the supply of power when a posture detecting means detects that a camera points downward and vertically, and when either a means discriminate operation for preventing image blur is needed or a placement discriminating means discriminate that the camera is placed with its top facing downward. Namely, whether vibration proofing operation is needed or not is discriminated, and the conduction of acceleration sensors 5a-5d is controlled to turn on and off. Thus, power saving is possible without deteriorating rise stability of a bypass filter, etc., accompanied with the turning-on of power supply when speedy photographing operation is needed. In addition, the camera's operability is not deteriorated.

摘要： PURPOSE:To obtain the half tone image of a high picture quality by monitoring a light quantity at the time of recording, comparing it with image data to record it and, simultaneously, applying a feedback to a recording light luminance for one picture element recording. CONSTITUTION:At the time of recording, a shutter 6 is opened. Next, a CPU13 outputs a color selecting signal and selects a filter 2 according to a sequence to be recorded. A light from a beam spot on a CRT1 passes the filter 2, lens 4, and a diaphragm 5. By a half mirror 8, one part is incident on an a-Si area sensor 9, and the other part is incident on a sensitive material 7. Then, the a-Si area sensor 9 generates a signal corresponding to an incident spot light luminance. The signal is amplified by an amplifier 10, passes a feedback gain adjustor 11, and is fed back to a luminance modulating signal. As a result, since a control is executed so as to make the recording light luminance into an aimed luminance value, the influence of a light quantity change due to a deterioration on the CRT1, the dirt of an optical system, etc., can be reduced.

摘要： PURPOSE:To automatically follow a moving object without the influence of a background by providing a means which drives a universal head based on the output of an object moving area detection means so that a camera on the universal head can follow and point the central point in an object moving area. CONSTITUTION:A signal from a light receiving element 2 is divided into two parts, which are stored in a memory 5a through a delay part 4 and directly in a memory 5b, respectively. If the object 15 moves to the right or left, a piece of data on visual fields is stored in the memories 5a and 5b with a difference of a t. When a subtraction part 6 subtracts the memory 5a from the memory 5b, only the moving signal of the object 15 leaves as a signal of any values apart from zero, and a detection part 7 detects the central point in the object moving area. A universal head drive amount calculation part 8 and a universal head memory part 9 calculate the drive amount so that the universal head 12 cam follow the central point in the object motor 11 is driven through a control part 10 so that the universal head 12 can point and follow the central point.

摘要： PURPOSE:To frame automatically a heat source such as a human body within a photographing field and to pick up a moving subject easily by using plural temperature detecting means having different visual fields. CONSTITUTION:Two pyroelectric bodies which are detecting bodies of a pyroelectric sensor 5 are arranged in parallel and differentially connected with each other in the sensor 5 and mutual temperature compensation is attained by outputting differential signals each other. If a heat source, e.g. a human body, is moved from the outside of the visual field into the visual field in front of the sensor 5, signal generating time from the pyroelectric bodies is delayed each other because the visual fields of the two pyroelectric bodies are different. Since the output pattern of the sensor 5 is changed in accordance with the moving direction of the heat source, the moving direction of the heat source can be discriminated by detecting the pattern. The output signal of the sensor 5 is digitized by a positive signal discriminating circuit 7 and a negative signal discriminating circuit 8 and inputted to a microprocessor 10 through an input circuit 9 to detect the pattern. Therefore automatic tracking for detecting the moving direction of the heat source such as the human body and framing the heat source within the photographing field.
