摘要:
The present invention provides a method and apparatus for automatically rotating a graphical user interface for managing portrait and landscape captures in an image capture unit. A method and apparatus for viewing an image in an image capture unit including a display comprises the steps of providing a first orientation associated with the image via step (700) and providing a second orientation associated with the image capture unit via step (702). It is then determined whether the first orientation is different from the second orientation via step (704), and the image is displayed in the second orientation if the first and second orientations are different from each other via step (706).

A method and apparatus are provided for preventing keystone distortion in a projected image. A projected image (750a) is produced by projecting light from a light source (102) through a deformed image (700a) rendered on a display device (110) of a projector (100) and onto a viewing surface (130) at a non-perpendicular angle. An original image (700) received for projection is deformed in proportion to the projection angle to generate the deformed image (700a), which is projected to yield the projected image (750a) having proportions closely matching the original image (700). The original image (700) may be resized for storage in memory and/or to fit within a specified area of the display device (110). The apparatus further comprises a digitizer module (206) for receiving the original image (700) and resizing it for storage and a generator module (208) for resizing the image to fit the display device (110). Deformation of the original image (700) may be performed in either or both of digitizer (206) and generator (208).
摘要:
An apparatus (10) for locking a focus position of a lens assembly without causing the lens cell (12) to tilt, comprising: a spacer (22) interposed between the lens cell (12) and the focus mount (14). The spacer (22) is received into a sleeve (16) that is integral with the focus mount (14). The sleeve (16) projects radially outward from the focus mount (14) such that the spacer (22) can be raised and lowered radially with respect to the focus mount (14). The spacer (22) has a cylindrical body (24) with a radial flange (26) at one end. Moreover, the spacer (22) has two ridges that extend downward from a lower surface of the flange (26), each of which is received into a corresponding groove on the sleeve (16), thus, preventing the spacer (22) from rotating within the sleeve (16). The spacer (22) also has an upwardly raised rim (30) extending from an upper surface of the flange (26). The rim (30) is slidably secured into a slot of the focus mount (14), which prevents lateral movement of the spacer (22). Further, a bolt (34) is coupled to an opening (28) within the spacer (22), such that one end of the bolt (34) is disposed and secured within the spacer (22) and the other end of the bolt (34) extends radially outward through the slot of the focus mount (14).

A signal processing circuit (1) comprises a first signal generator (10) which generates a DC-level (DL). A second signal generator (11) generates an AC-signal (AS) which is not related to the DC-level (DL). A combining circuit (12) combines the DC-level (DL) and the AC-signal (AS) into a combined signal (CS). And a common processing circuit (13) processes the combined signal (CS).

摘要:
A first voltage-to-current converter (Q07,U06A) responsive to a picture height adjustment control signal (V-SIZE) generates a first current (IURAMP) in a capacitor (C03) for producing a trace portion of a sawtooth signal (VSAW) in the capacitor having a rate of change that is adjustable in accordance with an adjustment of the control signal. A second voltage-to-current converter (Q09,U02A) responsive to the control signal generates a second current (I0) in a resistor (R09) for producing a third signal (base voltage of U01C) that is adjustable in accordance with the control signal. The sawtooth and third signals are coupled via a differential amplifier (U01B,U01C) to a vertical deflection winding (Ly,Fig. 1c) to produce a vertical deflection current (iy) in accordance with a difference between the sawtooth and third signals such that picture height adjustment does not affect vertical centering.
摘要:
Electro-optical display apparatus includes a plurality of modular units (M1-M4) each having a projector (5) for receiving electrical signals, converting them to optical images, and projecting the optical images via an optical projection system (18) onto a screen (4). The modular units (M1-M4) are arranged in a side-by-side array such as to produce a combined display on the screen. A calibration system detects distortions in the combined display caused by the projection system of each modular unit and modifies the electrical signals applied to the projector of each modular unit to correct the combined display with respect to the detected distortions.
摘要:
An electron beam tends to slope downwardly as it is deflected horizontally to form a raster in a video display apparatus. The sloping of the beam can cause geometric errors in the raster, for example orthogonality and parallelogram errors. A raster correction circuit (100) substantially offsets the downward slope of the electron beam by modulating a vertical deflection current (I V ) with an induced horizontal-rate raster correction current (I CORR ), thereby substantially eliminating orthogonality and parallelogram errors in the raster. In respective embodiments of an inventive arrangement taught herein, the horizontal-rate raster correction current (I CORR ) is induced in the vertical deflection coils (L V1 , L V2 ) by magnetically coupling a filament pulse waveform (11), a horizontal deflection voltage waveform, or a horizontal deflection current into the vertical deflection coils (L V1 , L V2 ).
