An information processing apparatus includes a feature extraction unit configured to extract feature points from each of a plurality of images of an object to be inspected captured from a plurality of viewpoints, an image quality evaluation unit configured to, for each of the plurality of images, evaluate whether an image quality based on a predetermined index satisfies allowable conditions for inspection works of the object, and an image stitching unit configured to stitch at least a part of the images, among the plurality of images, having the image quality that satisfies the allowable conditions according to a positional relation based on the feature points.

Abstract: When a user inputs a URL character string indicating data for an order document, the CPU receives data for the order document indicated by the URL and reading method data from the web server at the URL destination and prints the order document on a recording unit. The user then fills in circles on the order document to indicate desired content and feeds the order document into the manual-feed paper tray on the facsimile device. At this time, the facsimile device reads a user number and data regarding printing details and scrapbook entry details and transmits order data described as a URL to the web server.

Abstract: A printing apparatus includes a command input portion, an acquiring portion that acquires image data, a judging portion that determines if specified image data is included in the image data, a control portion and a printing portion that prints an image based on the image data onto a medium. Upon receiving the print command, a determination by the judging portion is performed, and when the judging portion determines that the specified image data is included, a first copy that includes invalidation processing on at least a section of the image is produced, and a second copy that includes invalidation processing on all of the image and the image in all subsequent copies that are printed thereafter is produced, to thereby execute printing of a number of copies that are specified by the print command and subsequently enter a state in which a next print command can be executed.

Abstract: In an image signal input apparatus that performs high-speed input processing of an image signal and, in particular, a brightness signal, a video signal is processed by a clamping circuit so as to achieve a constant reference level, and then input to an A/D converter. The A/D converter samples the video signal synchronously with a clock signal of a frequency 4fsc. The output of the A/D converter is input to a selector directly or via a 4-data arithmetic mean circuit. The 4-data arithmetic mean circuit obtains an arithmetic mean of every four consecutive data output from the A/D converter. The obtained 4-data arithmetic mean data correspond to the brightness signal. After the 4-data arithmetic mean data is stored in a memory through a DMA controller, the data is output to a personal computer via a Centronics® interface, thereby reducing the amount of data memory necessary for input processing to a quarter of the normal amount.

Abstract: An image processing apparatus includes a memory for storing image data which includes plural groups of image data, each group of image data corresponding to a line of pixels arranged in a primary scanning direction which is perpendicular to a secondary scanning direction. The image processing apparatus further includes a writing reduction circuit for reducing the image in secondary scanning direction by deleting selected groups of image data before storing the set of image data in the memory, and a reading reduction-enlargement circuit for enlarging the image in said another scanning direction and for reducing or enlarging the image in said one scanning direction at the time of reading out the stored set of image data from the memory.

Abstract: An image recording apparatus which records an image of an original document on an image receiving sheet with the use of a photosensitive recording medium, the image receiving sheet having front and rear faces differing in reflection ratio. To detect error in sheet face orientation, a sheet face sensor unit is provided upstream of a pressure developing unit which discriminates a face of the image receiving sheet. The sensor unit includes a light emitting element for emitting light toward the face of the image receiving sheet and a light receiving element for receiving light emitted from the light emitting element and reflected on the face of the image receiving sheet. A central processing unit computes a reflection ratio based on the data supplied thereto and produces a discrimination signal indicative of the face of the image receiving sheet based on the reflection ratio being computed.

Abstract: The invention provides apparatus for forming images at a high speed and with small power consumption, in which a discharge lamp for exposure remains `on` and electric power supplied to the lamp is reduced to such an extent that the lamp is turned down during standby period for exposure. The invention also provides image forming apparatus including a temperature detector for detecting the temperature of an exposure lamp, plural filters, actuators for moving the filters in and out of the optical path, and a controller for regulating the actuators based on temperature data, thus forming stable images irrespective of the temperature of the lamp. The invention further provides image forming apparatus including a cooling fan for cooling an exposure lamp and lamp temperature controller for maintaining the temperature of the exposure lamp constant by activating the cooling fan based on temperature data detected by a lamp temperature detector, thus forming stable images of a desirable color or tone.

Abstract: An image recording medium is provided with an identifying index indicative of whether or not one side of the image recording medium is a front side coated with developing agent. In another image recording medium coated with developing agent, electrical resistance material is coated on at least one side of the image recording medium. In a detecting device for the another image recording medium, an electrode unit is provided for measuring electric conductivity of one side of the image recording medium. A control unit is connected to the electrode unit for identifying the image recording medium on the basis of the electric conductivity measured by the electrode unit. In another detecting device, a light emitting unit emits light with which at least one of front and back sides of an image recording medium is illuminated. A light receiving unit receives light reflected from the at least one side of the image recording medium.

Abstract: An image forming apparatus that provides consistent images on an elongated web-like recording medium. The image forming apparatus forms the image on the recording medium as it is supplied from a supply member and passes across an exposure station. An associated winding member is detachably installed in the apparatus to take up the recording medium supplied from the supply member. Placed on the winding member are indicia containing information on the exposure and developing characteristics of the recording medium. The operation of the image forming apparatus is controlled according to the characteristics information that is read by a reading device prior to the attachment of a leading edge of the recording medium to the winding member during the automatic feed of the recording medium.
