The invention provides an image signal processing apparatus, an image signal processing method and a program. The image signal processing apparatus includes multiple color support distortion correcting units receiving a color signal of a correction target image, performing image distortion correction of a color based on a lens distortion characteristic and generating a correction image supporting the color. Each of the multiple color support distortion correcting units performs processing of receiving a reference signal indicating a pixel position in an input image applied to calculate a pixel value of an output correction image, and setting a pixel value of the pixel position indicated by the reference signal in the input image as an output pixel value.

An optical unit includes an incidence optical member for giving a different angle to each of a plurality of laser beams to form a color image and making the laser beam incident on a single polygon mirror rotation body; a single first reflecting mirror for reflecting the laser beam for each color reflected on the polygon mirror in the opposite direction to the incidence direction; and a single or plurality of second reflecting mirrors having Fθ characteristics for forming an image of each reflected laser beam reflected on the first reflecting mirror on the image formation position for each color.

In order to provide an image forming apparatus which can reduce color deviation at the time of forming an image on a medium, the present printing apparatus comprises an image forming unit which forms an image by superimposing images, each formed with corresponding color of ink, on a transfer film (46) while heating a thermal head (40), a film conveying device which conveys a transfer film (46), a sensor (Se1) which detects a stretch of the transfer film (46) occurring due to heating with the thermal head (40), a controller which controls the image forming unit to change a line cycle of the thermal head (40) in accordance with a stretch of the transfer film (46) detected by the sensor (Se1).

The present invention includes first pixels formed to have a first slit having an inclination angle with respect to a rubbing direction and second pixels formed to have a second slit having an inclination angle opposite to the first slit, and at least one of the first pixels having a positive polarity allocated thereto and at least one of the first pixels having a negative polarity allocated thereto exist in the same frame, and at least one of the second pixels having the positive polarity allocated thereto and at least one of the second pixels having the negative polarity allocated thereto exist in the same frame.

An image forming apparatus that suppresses occurrence of color shift in images transferred from image bearing members onto an intermediate transfer member. A surface of each of a first photosensitive drum and second photosensitive drums is charged. An exposure device, provided for each photosensitive drum, forms an electrostatic latent image by exposing an associated one of the charged photosensitive drums. A developing device, provided for each photosensitive drum, develops the electrostatic latent image with toner. An intermediate transfer belt friction-drives the photosensitive drums for rotation and has the developed images transferred thereon. Timing for exposing the second photosensitive drums is controlled based on a first surface distance from an exposure light irradiated position to a primary transfer position of the first photosensitive drum, and a second surface distance from an exposure light irradiated position of each second photosensitive drum to a primary transfer position thereof.

An image forming apparatus sets one of a plurality of modes including a monochrome mode of forming a monochrome image, converts a multivalued luminance signal into signal values of color material amounts to be used to form the image and forms the image using color materials based on the signal values. The color materials used in the forming when the monochrome mode is set include an achromatic color material and at least two auxiliary color materials which have hues opposite to each other and a chroma larger than that of the achromatic color material.

To prevent the local deterioration of a gear for colors and a gear for black and to prevent the occurrence of a color smear of a color image with an image forming apparatus which has a photoreceptor for colors for forming a chromatic color toner image, the gear for colors for rotationally driving the photoreceptor, a photoreceptor for black for forming a black toner image and the gear for black for rotationally driving the photoreceptor and permits the selection of a color mode to transfer the toner image formed on the photoreceptor for colors and the photoreceptor for black and a monochromatic mode to transfer only the toner image formed on the photoreceptor for black to a recording material. In the color mode, while the prescribed positions of the gear 32Y, 32M, and 32C for colors and the gear 32BK for black are maintained, their gear 32Y, 32M, and 32C for colors and the gear 32BK for black are stopped in the positions different from their rotation start positions. In the monochromatic mode, the gear 32BK for black is stopped in the same position as the rotation start positions.

PROBLEM TO BE SOLVED: To provide a vertical alignment type liquid crystal display device with a normally white mode, which inexpensively suppresses a color shift occurring when the device is observed in lateral directions.SOLUTION: The liquid crystal display device includes a first substrate 1, a second substrate 2, a liquid crystal layer 7, a first polarizing plate 5, a second polarizing plate 6, and first to third optical plates 21, 22, 23. Absorption axes of the polarizing plates are disposed substantially orthogonal to each other and at an angle of about 45 with respect to an alignment direction of the liquid crystal layer at substantially the center in a layer thickness direction when an electric field is applied. The first optical plate 21 is a quarter-wave plate having an in-plane slow axis disposed at an angle of about 45° with respect to the absorption axis of the first polarizing plate 5. The second optical plate 22 is a quarter wave plate having an in-plane slow axis disposed at an angle of about 45° with respect to the absorption axis of the second polarizing plate 6. The third optical plate 23 has negative biaxial optical anisotropy and has an in-plane slow axis disposed substantially orthogonal to the absorption axis of the first polarizing plate 5.SELECTED DRAWING: Figure 1
