Image output apparatus, portable terminal apparatus, and captured image processing system

Abstract

The invention relates to an image output apparatus, a portable terminal apparatus, and a captured image processing system. The image output apparatus receives a single piece of captured image data from a portable terminal apparatus, and carries out, in accordance with the single piece of captured image data received, a high resolution correction for creating high resolution image data which has a higher resolution than the single piece of captured image data. Then, the image output apparatus carries out an output process in which the high resolution image data created is outputted. This provides a captured image processing system which allows an image output apparatus to output an image captured by a portable terminal apparatus while the image is improving in resolution such as text readability.

Description

technical field [0001] The present invention relates to a captured image processing system that outputs an image captured by a portable terminal device through an image output device. Background technique [0002] Along with Internet technology, cellular phone, wired, and wireless communication technologies have been developed and widely spread. Using this technology, it is possible to transmit images from a mobile terminal device such as a mobile phone to an image output device connected to the Internet at a destination, and have the image output device print. [0003] For example, in Patent Document 1, digital image data collected by a mobile information device such as a digital camera, a PDA with a camera, or a portable personal computer is sent to a server via a network. In the server, the received digital image data is subjected to image processing such as adjustment of brightness, color, and size, and is embedded in an image area of ​​a stored template for synthesizin...

Problems solved by technology

[0008] However, in the case of RGB filters used in mobile phones and digital cameras, or complementary color (CMY) filters, the filters are arranged in a two-dimensional plane with respect to each color, so there are differences between images captured by a mobile terminal device and images captured by a scanner or the like. Compared with the read image data, it becomes an image whose resolution is reduced by about 1 / 3 to 2 / 3, and there is a problem that the readability of characters is poor.

[0009] Specifically, in scanners and the like, since RGB linear sensors are used, respective color data can be read for each pixel. , or arranged in RGRGRG... / GBGBGB... in each row, there are color components without filters in each pixel, so the resolution is low
