Imaging device and imaging apparatus

An imaging device includes a plurality of pixels each of which includes a microlens, first and second photoelectric conversion portions. The first photoelectric conversion portion is between the microlens and a focal point of the microlens. The second photoelectric conversion portion is at a position being different from that of the focal point on a plane which is parallel to an imaging plane and which contains the focal point, and has a photoelectric conversion region deviated from an optical axis of the microlens in a direction of the imaging plane. The plurality of pixels includes a first pixel group and a second pixel group. The photoelectric conversion region is deviated from the optical axis in the direction in the first pixel group. The photoelectric conversion region is deviated from the optical axis in the direction to be opposite to the first pixel group in the second pixel group.

Image reading apparatus, method of controlling image reading apparatus, program, and computer readable storage medium

This invention has as its object to obtain a high-quality read image from which dust or scratches have been removed by an image reading apparatus which reads image information on a transparent original by synchronously scanning a light source unit and image reading unit. To this end, upon reading a transparent original, infrared LED chips on a dust / scratch detection LED substrate and a transparent original illumination lamp are turned on to make alignment between the LED substrate and the image reading unit, and dust / scratch detection image information is obtained by synchronously moving the light source unit and image reading unit in the subscanning direction.Subsequently, alignment between the transparent original illumination lamp and image reading unit is made, and image information of the transparent original is obtained by synchronously moving the light source unit and image reading unit in the subscanning direction.

Rotary member driving mechanism, and image forming apparatus employing this mechanism

For a conventional image forming apparatus, since a waveform in a phase opposite that of a rotation change waveform is applied to a drive motor to rotate a photosensitive member, a correction to cancel the rotation change is also performed for a sudden rotation change of the photosensitive member, or for a high frequency change in the noise component generated by a rotation detector. As a result, since the drive motor can not be smoothly rotated, and since the drive torque of the drive motor is not stabilized, small vibrations always occur in the photosensitive member and cause image deterioration, such as a jitter or banding. Therefore, according to the invention, cycling due to the eccentricity of the photosensitive member is represented by using a continuous repetition function, and the waveform in the opposite phase is employed as a drive instruction value for the driving unit. With this arrangement, smooth rotation of the driving unit can be obtained, and the offsetting of the change is performed.

One way vision film for ink jet printing, printing film, and method for producing them

A one-way vision film includes a white film base material; a shrinkable color tone layer on one side of the base material; and a self-adsorptive foamed layer on the base material opposite to the shrinkable color tone layer. The one-way vision film is perforated with through-holes. The self-adsorptive foamed layer has an adhesive function attachable to a surface onto which the film is attached and is printable. Since the printing ink is deposited to the bottoms of the open pores while not closing the openings of the open pores, open pores exposed to the surface of the foamed layer function like suction cups adhering onto a smooth surface. Accordingly, there is no need for forming ink-receptive and pressure-sensitive layers, unlike a conventional film, so the film can have a low cost, three-layer structure. The one-way vision and printed film is easily attachable onto a smooth and transparent substrate like glass.
