Abstract in simplified Chinese:本案系利用一低分辨率光电转换模块,来作同一尺寸之高分辨率用之影像扫描仪,可提高一倍分辨率,即为原来两倍分辨率。并比较同一分辨率之影像扫描仪,本设备因为使用该低分辨率光电转换模块,而得到低成本之效益,本案之光学组件均不动,故其分辨率和光学品质可维持一定。
Abstract in simplified Chinese:借着使影像(image)穿越一光学快门(optical shutter)投影在一光传感器上面,就能以光学方式扫描一影像。在一模范实施例中,虽然使快门变成实质不透明,除了经选定之实质透明的一些邻接像素群外﹔可是仍会使影像穿越光学快门而投影。然后,借着推进这些像素群,以一种预定图案(pattern)的方式越过快门,进而扫描文档内容。譬如说,快门可能包括一LCD(液晶显示)屏幕。要扫描一份文档,首先将该文档向着快门放置。当一光源指引着光学穿越文档及快门时,就会使快门变成实质不透明,除了经选定之实质透明的一些邻接像素群外。然后,借着推进这些像素群,以一种预定图案的方式越过快门,进而扫描文档内容。可能会将文档向着快门的每一边放置--接近光源或接近光传感器。
Abstract:
This invention provides an image forming apparatus capable of reliably printing security information even when image data of an original document that is obtained by a reading unit contains security information and an area where the security information is not contained is set as a print area, and a control method thereof. To accomplish this, when image data of an original document contains security information, the image forming apparatus extracts image the security information from data, and sets a print target area from an area indicated by the image data of the original document. When an area corresponding to, from which the security information is extracted, is not contained in the set print target area, the image forming apparatus executes printing using the extracted image data corresponding to the security information, and the image data corresponding to the print target area.
Abstract:
The length of the process from capturing an image by an optical reading unit to discharging the medium is shortened, and throughput improved. A media transportation mechanism conveys a medium to be scanned. An optical reader disposed to the medium transportation path optically reads the conveyed medium. A storage unit stores the captured image. A transmission unit reads and transmits the captured image stored in the storage unit to another device. A discharge control unit discharges the medium while the captured image is being transmitted to the other device after the optical reader finishes scanning the medium.
Abstract:
A display device includes a housing, a liquid crystal panel member, numerous camera modules, a light emitting device and a processing unit. The housing defines a slot configured for allowing an display medium to enter the display device. The liquid crystal panel member is received in the housing. The camera modules are positioned in the reflective housing and each is configured for capturing a sub-images of a corresponding portion of the display medium. The light emitting device is configured for emitting light to the display medium. The processing unit is configured for obtaining an image of the display medium by synthesizing the sub-images of the corresponding portions of the display medium.
Abstract:
The invention relates to a method for illuminating printing plates (5) in which the light from a light source (2) is imaged on a two-dimensional light modulator (4) having a plurality of rows of light-modulated cells (8), and said light is modulated thereby, whereupon the light modulator (4) is imaged on light-sensitive material (5) via an imaging beam path (11), wherein the light-sensitive material (5) is moved relative to the light modulator (4) substantially perpendicularly to the direction of the rows of light-modulated cells (8) at a relative speed and wherein the data pattern to be imaged on the light-sensitive material (5) is displayed beginning in the first row of the light modulator (4) in each row consecutively during a respective exposure time (T, T′) and then moved to the subsequent row of the light modulator (4). In order to improve said method, the invention proposes that the image (10) of the data pattern be held substantially stationary relative to the light-sensitive material (5) during the exposure time (T, T′).

Abstract:
An image reading device having plural image sensors and a reading controller is disclosed. The image reading device is for obtaining image data over a subject by joining sub-image data outputs read by the image sensors, each image sensor comprising: a signal amplifier; and an A/D converter for converting an analog value output from the image sensor to a digital value; whereby the reading controller adjusts an amplification factor of each signal amplifier so that a read value of a white board read by each image sensor becomes a predetermined value.
Abstract:
The present invention discloses a shared image scanning method and picture scanner thereof The method includes the steps of: sharing a desired scanning document into image areas; constructing images captured from each image area into a whole document sensing image to be used by the scanner. The scanner includes reflecting mirrors, light source modules and image sensing modules in a frame. The reflecting mirrors are installed in the frame with an interval apart from each other and corresponding to the image areas. The light source modules project lights onto the image areas to produce document images which are captured by the corresponding image sensing module and converted into image signals, and processed by an image processing unit to produce a whole document sensing image signal. Thus, the scanner applying the shared image method of the present invention can complete a document scanning quickly.
