摘要:
A superresolution electro-optic imaging system operates in a manner that takes into account the different subsystems. For example, rather than designing the optical subsystem to be diffraction-limited, the optical subsystem can be designed in a manner that is better suited for subsequent superresolution processing and/or that reduces aliasing effects.

There are included a first quadrature modulation part (5) that divides an input signal into an I signal and a Q signal having a phase orthogonal to the phase thereof and uses a baseband frequency to perform frequency conversions of the I and Q signals, thereby performing a quadrature modulation; and a second quadrature modulation part (8) that uses in-phase and quadrature carriers of FM frequencies, which are 90 degrees out of phase with respect to each other, to perform frequency conversions of the I and Q signals, which are generated by the first quadrature modulation part (5), thereby performing a quadrature modulation. Thus, the phases of the I and Q signals, which are shifted by 90 degrees with respect to each other by the first quadrature modulation part (5), are further shifted by 90 degrees with respect to each other by the second quadrature modulation part (8), thereby providing frequency components the phases of which have been inverted, whereby the unwanted harmonic components at the spurious sides of a target frequency can be attenuated.

An image forming apparatus includes a sheet conveyance path, a pair of rollers configured to rotate in a conveyance direction to convey a sheet in the path by holding the sheet, and to reversely rotate in a direction opposite thereto. The reverse rotation is regulated so that the pair of rollers may reversely rotate within a predetermined amount. A sub-unit is releasable from a body of the image forming apparatus.

A differential amplifier circuit at the input stage is configured with a twin differential type having a first differential amplifier circuit (11) and a second differential amplifier circuit (12), respective outputs of which are received by a first and a second source-grounded amplifier (M5, M10). The second source-grounded amplifier (M10) is connected to a current mirror circuit (M11, M12), which is driven by the drain current of the second source-grounded amplifier (M10). With this configuration, the dynamic range for the upper half portion of an alternating signal output from an output terminal (OUT) is determined by the current supply capability of the first source-grounded amplifier (M5) and the dynamic range for the lower half portion is determined by the current supply capability of the second source-grounded amplifier (M10). This eliminates the need of a constant current circuit of a large current for generating a signal having lower half portion in which the waveform distortion is improved.

A toner container includes a longitudinal container body and a held portion. The longitudinal container body has a first end and a second end distal to the first end in a length direction of the container body. The container body includes a gear configured to engage with a drive gear provided in the main body. The held portion is attached to the first end of the container body and configured to be detachably attached to the toner-container holder. The held portion includes a toner outlet, is configured to be held by the toner-container holder in non-rotating manner, and is biased downwardly by a force applied from the drive gear to the gear when the drive gear rotates.

A method and apparatus is disclosed herein for enhancing accuracy of jumping by incorporating interestingness estimates. In one embodiment, the method comprises serially displaying a sequence of page images; receiving a user input to stop sequencing through the page images; determining a location of a page image in the sequence of page images representing a point at which the user intended to stop in the sequence of page images but for display speed of the sequence of images and user reaction time in providing an indication of the point at which the user intended to stop, the location being selected based on visual distinctiveness of the page image at the location and the reaction time associated with the user; and automatically jumping back to the page image at the location in the sequence of page images.
