摘要:
A image edit apparatus in which area data of 16-bit width have been stored at the memory locations of the corresponding addresses of the respective memory planes of a plane memory 403. The operation of reading area data therefrom by a pseudo sync signal starts before a line sync signal becomes active. A density-conversion/area generating circuit 405 converts the data format from the plane type to the pixel type, so that area commands are generated. Then, the circuit 405 reads an edit command out of a logic RAM, using the area command as address, and outputs the command. By reading the area data earlier and processing that data, a delay in the density-conversion/area generating circuit can be absorbed, so that the output edit command is synchronized with the image data.

An image reading apparatus including: a paper supply section; a transporting path for transporting a document supplied from the paper supply section; a first sensor which reads an image on a first surface of the document from one side of the transporting path; a second sensor which reads an image on a second surface of the document from the other side of the transporting path; and an image processing section which is constituted so as to correspond to a first reading mode in which two sides of the document are read using the first sensor plural times, and a second reading mode in which two sides of the document are read using the first sensor and the second sensor, and which makes a registration position and direction of an output image in both the first and second reading mode the same.

An image reading apparatus includes: a light source that irradiates a document; a sensor that receives reflection light reflected from the document; a reference member that is read by the sensor; and an abnormal site detection unit that detects, using first reading data acquired by reading the reference member according to a first reading condition set to the light source or the sensor and second reading data acquired by reading the reference member according to a second reading condition, which is different from the first reading condition, set to the light source or the sensor, abnormal sites in the first reading data or the second reading data.

An image reading unit has a line sensor for reading a document and producing image data. A line counter counts the number of lines that are scanned during a period from a start of reading by the image reading unit until a time point when an edge of the document is read. A ROM stores, in advance, a corresponding relationship between error accumulation values and the numbers of lines. A control section reads out, from the ROM, an error accumulation value corresponding to the number of lines counted by the line counter, and determines the position of the edge of the document in the auxiliary scanning direction by subtracting the readout error accumulation value from a product of the counted number of lines and the auxiliary scanning pitch, thereby detecting a document length in the auxiliary scanning direction.

An image data processing device has an image identifying unit and a file generating unit. The image identifying unit identifies a common image that is common to each page and a non-common image that differs from page to page on the basis of inputted image data including a plurality of pages. The file generating unit generates separate files of the common image and the non-common image.

An automatic grading method has processes of reading, identifying and calculating. A process of reading a document is performed and the document has one or more answers. A process of identifying the answers from the document is also performed. A process of calculating a score of the document based on a score of each answer is performed.

The invention provides an image reading apparatus includes a feeder that feeds a sheet, a transfer path on which the sheet fed by the feeder is transferred, a first reading unit that captures a first image on a first face of the sheet from one side of the transfer path to obtain first image data, a second reading unit that captures a second image on a second face of the sheet from the other side of the transfer path to obtain second image data, and a correction unit that substantially equalizes image density of the first image data and that of the second image data in a case where the first image and the second image are captured at a single transfer of the sheet through the transfer path.
