摘要： An automatic focusing camera having an indicator for producing an indication when the subject being photographed is too near the camera to be brought into focus. It also provides an inhibit signal if this situation exists thereby precluding operation of an exposure cycle. When the camera is operated in its flash mode, an indicator produces its indication if the subject is outside a predetermined range within which the shutter mechanism is capable of producing a properly exposed photograph under flash illumination and an inhibit signal is also provided in this situation to thereby preclude operation of an exposure cycle.

摘要： A method and apparatus for producing a zoom system within a printer is disclosed where the zoom system is adapted to selectively enlarge or reduce an original image such that the enlarged or reduced image can be printed onto a recording medium. Further, the zoom system is adapted to selectively adjust an aspect ratio of the original image. The zoom system utilizes a phase lock loop to produce a pixel clock in a fast scan direction and a governing motor control to alter incremental movement of the recording medium in the slow scan direction, thus, individual pixel size can be manipulated by varying a frequency of the pixel clock to alter a width of the pixel projected onto the recording medium and by governing overlap of successive print lines, and repeating print lines if necessary, to alter a length of the pixel.

摘要： The operational range of an adjustable focus lens is subdivided into a plurality of focus zones, of finite size, by a lens control system that produces a plurality of discrete signals representative of said focus zones, said control system utilizing bidirectional drive means to position the movable element of said lens to one of said focus zones from any position within said operational range in order to focus an image of a remote object at an image plane. The present invention optimally increases the focusing speed and the focusing repeatability of said control system while equalizing and minimizing the focusing error introduced into said control system resulting from the use of such focus zones with bidirectional drive means, by anticipating the arrival of said movable lens element at the desired focus zone, disabling the lens drive means for a limited period of time prior to the time that said lens element arrives at said desired focus zone, and then having said drive means provide a pulsating driving force to said movable lens element until said movable lens element reaches said desired focus zone.

摘要： A flash camera having a range finder, a blade position sensor for producing an output representative of the position of the displaceable blades of a scanning shutter, a flash firing apparatus that includes a position/distance converter responsive to the output of the range finder for producing a representation of the desired flash-fire position of the blades, and a coincidence detector responsive to the output of the blade position sensor for firing the flash unit when the blades reach the position at which the exposure aperture established by the blades will effect proper flash exposure of the subject. In one embodiment of the invention, the converter is in the form of a digital memory whose addresses represent subject distances and whose contents at a given address represents the fire-flash position for the distance specified by the given address. In a second embodiment of the invention, the fire-flash position is generated from a scaled clock.
