  • Patent number: 8266625
    Abstract: An image processing apparatus that enables to start an application that is required to start by stopping an application that is not used by a user to reserve an available memory capacity when receiving a startup request. A first determination unit determines a memory usage of the application that receives the startup instruction. A second determination unit determines an available memory capacity. A third determination unit determines an application that is not used by a user. A stopping unit stops the application determined by the third determination unit among the executing applications when the memory usage determined by the first determination unit is more than the available memory capacity determined by the second determination unit. A starting unit starts the application that receives the startup instruction using the available memory capacity that increases because the stopping unit stops the determined application.

  • Patent number: 8265531
    Abstract: An image forming apparatus which is capable of detecting the direction and amount of an image shift in the main scanning direction without wasting toner, to thereby provide a higher-quality image with reduced running costs. A conductor is disposed such that the conductor partially overlaps an electrostatic latent image line formed on a photosensitive drum in a manner extending in a main scanning direction of the photosensitive drum, while moving relative to the electrostatic latent image line. The conductor generates induced current by the relative motion. An image shift in the main scanning direction is detected based on a result of measurement of the induced current generated by the conductor.

  • Patent number: 8259123
    Abstract: An image processing apparatus processes compression encoded data of a moving picture and outputs image data divided into a plurality of frames for displaying of the moving picture on a display device. A host CPU outputs a decoding command and a drawing command separately from each other. The decoding process on the compression encoded data can be performed in an independent manner from the drawing process of reflecting the image data, which are the decoding results, on the display object. At this time, a display control section executes the drawing process based on the image data stored in a ring buffer in accordance with the drawing command. Therefore, the host CPU can freely control timings at which the moving pictures are displayed on the display device.

  • Patent number: 8256362
    Abstract: First calculation section calculates, on the basis of sewing data, a sewing-progressing direction angle for rotating a rotary cylinder to orient an embroidering material, guided by a guide lever of a zigzag sewing head, in a sewing-progressing direction. Second calculation section adds or subtracts a zigzag-swinging angle to or from the sewing-progressing direction angle to thereby calculate a target rotational angle of the rotary cylinder. Swinging mechanism may be provided for swinging the guide lever relative to the rotary cylinder, and a swinging amount corresponding to the swinging angle of the rotary cylinder may be added to a width of zigzag-swinging by the swinging mechanism. Alternatively, every swinging movement necessary for zigzagging the embroidering material may be set by the swinging angle without the guide lever being caused to swing relative to the rotary cylinder.
