20090028381 | DEVICE CAPABLE OF ADJUSTING TWO-DIMENSIONAL CODE - An image forming device is provided which embeds a decodable two-dimensional code when embedding (printing) a two-dimensional code in an original document. The image forming device represents additional information by associating virtual points with dots in one-to-one correspondence and arranges dots in positions deviated from virtual points associated with the dots. The image forming device includes a determining unit for determining intervals between the virtual points and virtual points adjacent to the virtual points and determining sizes of the dots, and an arranging unit for arranging dots having the determined sizes to respective virtual points having the determined intervals. The determining unit may determine dots to have sizes other than sizes proportional to the determined intervals. | 01-29-2009 |
20090210732 | INFORMATION PROCESSING APPARATUS AND METHOD OF CONTROLLING THE SAME - This invention provides an information processing apparatus which includes a first storage unit and a second storage unit and implements a function of causing the first storage unit and the second storage unit to store data redundantly while maintaining a power saving mode even upon receiving an access request from an external apparatus in the power saving mode, and a method of controlling the same. To accomplish this, upon receiving an HDD access request in the power saving mode, the information processing apparatus operates after transiting to an HDD access mode in which only minimum necessary functions are activated without activating the main CPU. The contents of the HDD changed during the HDD access mode are stored as history information. Upon transiting from the power saving mode to the normal operating mode, the data in another HDD is updated in accordance with the history information, thereby implementing a mirroring function. | 08-20-2009 |
20100098333 | IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD AND IMAGE PROCESSING PROGRAM - An image processing device and an image processing method provided herein are capable of achieving data compression with reduced image degradation even if the data is image data entered from an input device such as a scanner. The entered original image data is divided into 2×2 pixel blocks. Two-color-form compression processing and four-color holding compression processing are performed on a block-by-block basis. The compression result data which leads to a smaller one of the differences in gradation value between the original image data and the two-color-form compression difference data and between the original image data and the four-color compression difference data is output as the compression processing result of the block. | 04-22-2010 |
20100183234 | APPARATUS, METHOD, AND PROGRAM - It is an objective of the present invention to provide an apparatus by which the processing required to perform the average density storage method on the hardware can be performed with a higher speed. | 07-22-2010 |
20110317232 | IMAGE PROCESSING APPARATUS, CONTROL METHOD, AND COMPUTER-READABLE MEDIUM - An image processing apparatus comprises: an unit configured to compress image data based on values of pixels and a layout of the pixels for each tile including the predetermined number of pixels; an unit configured to calculate a representative value from the values of the pixels included in the tile; an unit configured to determine based on a distribution of the representative values of tiles included in a first area including the first number of tiles whether or not a tile of interest included in the first area is to be corrected; an unit configured to calculate a correction value for the tile of interest based on the representative values of tiles included in a second area including the second number of tiles; and an unit configured to add representative values of the tiles, determination results of the tiles, and the correction value to the image data compressed. | 12-29-2011 |

20120290855 | INFORMATION PROCESSING APPARATUS, METHOD FOR CONTROLLING THE SAME, AND STORAGE MEDIUM - An information processing apparatus includes a processing unit, a power supply control unit configured to control powering on and off of the processing unit, and a controller unit configured to access the processing unit irrespective of a power supply state of the processing unit. The power supply control unit powers off a processing unit that is not in use, powers on a processing unit that is accessed by the controller unit, and outputs a predetermined control signal to the controller unit. The controller unit recognizes that an error occurs in a case where, after accessing a processing unit, the controller unit does not receive a response from the accessed processing unit until a time-out time elapses, and delays recognizing the error when the control signal is received. | 11-15-2012 |
20140157031 | IMAGE PROCESSING APPARATUS, ELECTRONIC APPARATUS, DETECTION DEVICE, METHOD FOR CONTROLLING IMAGE PROCESSING APPARATUS, METHOD FOR CONTROLLING ELECTRONIC APPARATUS, AND METHOD FOR CONTROLLING DETECTION DEVICE - An image processing apparatus that operates in a first power state or a second power state in which power consumption is smaller than in the first power state includes a detection unit that includes regions in which an object is detected, an analysis unit configured to analyze results of detection obtained in the plurality of regions, wherein the analysis unit enters a power saving mode in the second power state, a control unit that causes the analysis unit to return from the power saving state in a case where an object has been detected in any of the plurality of regions included in the detection unit in the second power state, and a power control unit that, in a case where the analysis unit determines that an object has approached the image processing apparatus, shifts the image processing apparatus from the second power state to the first power state. | 06-05-2014 |
20140253938 | IMAGE PROCESSING APPARATUS AND CONTROL METHOD - If a pyroelectric sensor does not detect a heat source after it is determined that the heat source has moved outside a detection region of the pyroelectric sensor, an image processing apparatus is controlled to change from a first power state to a second power state. If the pyroelectric sensor does not detect a heat source before it is determined that the heat source has moved outside the detection region of the pyroelectric sensor, the first power state is stayed in. | 09-11-2014 |
