Picture recording system, image data source device and picture recording device

Abstract

An image recording system, an image data source device and an image recording device are provided. Among them, the Non-PC printer driver controls the quantization of image data at the quantization resolution (resolution 1), and converts the quantization data quantized at the quantization resolution to the data resolution (resolution 2). Control and control of transferring the data converted into the data resolution to the engine unit of the image output device, and the engine unit of the image output device converts the data of the transferred data resolution into the recording resolution of the recording medium (resolution 3 ) to control, and at the same time, make the quantization resolution lower than the data resolution value. Thereby, even in an environment without a sufficiently large memory or a high-speed CPU, it is possible to provide image output maintaining image quality and speed, and to flexibly respond to various environments.

Description

technical field [0001] The present invention relates to an image recording system, an image data source device, and an image recording device that expand image data into recording data corresponding to a predetermined dot array, and use a matrix mode process for recording an image on a recording medium with a plurality of recording elements. . An image processing method and program. More specifically, it relates to an image recording system capable of providing high-quality images at high speed, an image data source device, an image recording device, an image processing method, and a program. Background technique [0002] Currently, in recording devices that record images on recording media such as paper, there is an effort to increase the resolution of image data in order to increase the image quality. However, if the image data becomes high resolution, the amount of data to be processed is large, and there is, for example, a host computer (host, host PC) that transmits the...

Problems solved by technology

[0016] In the processing of the control unit of the PD printer system, as in the case of the Non-PC system, it is not possible to expect a significant increase in cost to have sufficient memory and a high-speed CPU like a PC. The processing of the printer driver is used as it is, and the image quality and speed cannot be maintained

In fact, in the PD printer system that has been commercialized now, there are few products that can make full use of the printing speed in the engine unit of the printer due to the processing load in the controller unit.

[0017] In addition, regarding these problems, even in the case of using the matrix recording method described in the prior art, it is necessary to pre-embed PD-specific specifications in the engine unit of the basic printer, which is very important for the basic printer alone. Redundant specifications, which may cause problems such as storage units that may affect the program

[0018] In particular, when the basic printer has been commercialized, in the PD printer with the control unit added as an accessory, the processing speed of the control unit cannot be reached at the data resolution that the printer can receive, and the engine unit cannot be fully satisfied. print speed problem

[0019] That is to say, it is expected that the problems in the system for image output from devices other than PCs that are more popular in the future to the printer are roughly as follows: (1) If the processing of the printer driver performed on the PC is used as it is, the image processing unit The load increases, and the image quality and speed cannot be maintained (including the overall speed of image processing speed, data transmission speed, and printing speed)

(2) In order to adopt the matrix recording method to solve the above problem (1), there are various working environments, and it is difficult to include all suitable matrix recording methods in the printer engine
