摘要:
A liquid crystal display device for a camera, so designed to be illuminated by means of the artificial light so that the display value can clearly be observed, even when the photographic atmosphere is dark.
摘要:
A liquid crystal cell is provided within a camera viewfinder. In the cell, a liquid crystal is sandwiched between a resistance layer mounted on a substrate and another substrate-mounted layer which may be either resistive or conductive. Suitable means mask at least the end portions of the display of the liquid crystal cell. In operation, voltages corresponding to photographic conditions are applied to the layers to produce analog data indicative of photographic conditions.
摘要:
In the disclosed liquid crystal display system, one of two opposing base plates that sandwich an electrooptic liquid crystal between them is divided into separate electrodes or constitutes a homogeneous transparent resistance. A source of power energizes this electrode so as to produce a gradient or stepped voltages between the divisions, and a data voltage is applied to the other electrode so that one section of the sandwiched electrodes can effect light differently than the other sections and thereby display information.
摘要:
By providing a liquid crystal cell nearly at the position of the clear vision of the view finder optical system together with a means for masking the display part of the liquid crystal cell the noise appearing on the boundary between the display part and the object view field is eliminated while the invasion of dusts is avoided, whereby further by means of the liquid crystal cell the alarm for the improper exposure, the alarm of the consumption of the power source battery and so on are displayed besides the photographic informations.

In an instant, self-developing, and folding camera, a built-in flash unit is disabled as long as the camera is folded. According to another aspect, the flash is disabled after each photograph until the feed motor that drives the film during development has completed its operation. A collapsible bellows forms a dark space between first and second housing sections. When the bellows are folded the flash is drawn to the first section by coupling means. When the bellows are extended the coupling means draws the flash into an operative position.
摘要:
In the disclosed folding camera, a built-in flash is disabled and displaced into an inoperative position within the regular contours of the camera housing when the housing is folded. When the housing is extended, the flash may be set either in an operative enabled position outside the regular housing contours or in the inoperative disabled position within the contours.
摘要:
A display device comprising a first semiconductor stripe and a second stripe of composite structure in which a great number of successive areas alternate between a semiconductor material having different type with respect to that of the first stripe and an insulating material or materials and which is positioned in side-by-side contact relation to the first stripe to establish P-N junctions. A resistor stripe connected lengthwise to the second stripe so that a voltage proportional to a value of information which is desired to be displayed is applied across a third stripe when first stripe is negatively biased, a corresponding number of successive semiconductor areas in the second stripe are caused to emit visible light, giving a viewer the impression of a continuous luminous stripe having a length representative of the information value.
摘要:
The present invention relates to a camera using a photo-sensitive sheet material of self developing process type, which can actuate a photo-sensitive material take out device to take out the exposed photo-sensitive material sheet material to outside of the camera while conducting self developing process thereon, selectively by an electric motor or manually, and has a checking device to check whether or not the voltage of a battery to drive said electric motor is at a level to be able to properly activate said photo-sensitive material take out device, further has a means to direct to stop power supply to said motor when the voltage of said battery is below said level and to activate said photo-sensitive take out device manually.
摘要:
The present invention relates to an exposure control device for a camera for obtaining a proper exposure taking the differences of the films to be used into consideration, so designed that an exposure amount control circuit for controlling an exposure amount by means of a first light measuring circuit for measuring the light reflected from the film plane is provided, while a second light measuring circuit for measuring the light reflected from the shutter plane and/or the film plane is provided in such a manner that by means of the output of the second light measuring circuit the control output value of the exposure amount control circuit is compensated so as to obtain a proper exposure amount.
摘要:
In an image read system which reads an image recorded on a film capable of holding incidental information of the image in an area different from the area where the image is recorded, the incidental information of the image recorded on the film is read, and the read image and the incidental information is processed and outputted as data of a single image.
