Problems solved by technology

When the correspondence accuracy between positional data and image data is low, for example, the quality of an image generated by synthesizing image data based on positional data cannot be sufficiently high
[0005] In addition, this problem is not limited to the case of synthesizing image data based on position data, but is a common problem in the case of associating position data representing a position with image data representing an image.

Deformed example 1

[0057] In the above-mentioned embodiment, the mouse scanner 100 was used as an example for explanation, but the present invention is not limited to the mouse scanner 100, and can be applied to devices generally having a position detection unit, a light source unit, an imaging unit, and an image processing unit. . For example, the present invention is also applicable to manual scanners that do not function as a mouse.

Deformed example 2

[0059] In the above-mentioned embodiment, the mouse scanner 100 sends the position data and the image data corresponding to each other to the PC200, and the PC200 uses the position data and the image data for splicing, but the mouse scanner 100 itself may use the position data and the image data for splicing. Stitching, and sending the combined image to PC200.

Deformed example 3

[0061] The configuration of the computer system 10 in the above-described embodiments is always an example, and the configuration of the computer system 10 can be changed in various ways. For example, the size (number of pixels) of the CMOS sensor 132 is not limited to that described above. Furthermore, the scanner mechanism 130 may be an image sensor other than the CMOS sensor 132 , and may have an area image sensor including a plurality of pixel groups whose exposure periods differ from each other as an imaging unit. In addition, the present invention can also be applied when the scanner mechanism 130 has a line image sensor as an imaging unit. Furthermore, the scanner mechanism 130 may have a light source other than the LED 134 . In addition, the mouse scanner 100 does not need to correspond to the USB interface, and may be connected to the PC 200 through another interface.

Abstract

An apparatus includes: a position detection section which detects the position of the apparatus at predetermined detection timing; a light source section which emits light at light emitting timing synchronized with the detection timing; an image-taking section which takes the image of a photographic subject by using the emitted light; and an image processing section which matches the position data indicating the detected position of the apparatus and the image data obtained by the image-taking.

Description

technical field [0001] The present invention relates to a technique for performing image processing for associating positions with images. Background technique [0002] There is known a device that has a position sensor and a linear image sensor, and functions as a pointing device (mouse) as well as an image scanner (for example, refer to Patent Document 1). In this device, image data is acquired by imaging while the device is moved, and the acquired image data of a plurality of columns (or rows) is associated with position data indicating a position detected by a position sensor. This image data is synthesized based on the corresponding position data, and one image data representing a two-dimensional image can be generated. [0003] Patent Document 1: Japanese Unexamined Patent Application Publication No. 11-345074 [0004] In the prior art described above, there is room for improvement in the correspondence accuracy between position data representing a position and image...
