摘要： In an image processing apparatus which performs an error diffusion process to multivalued image data consisting of plural density components and outputs a result of the error diffusion process, the process result from a first error diffusion unit performing the error diffusion process based on a density value of a first density component included in the plural density components or the process result from a second error diffusion unit performing the error diffusion process based on the density value of the first density component and a density value of at least one density component included in other density components is selected according to a predetermined condition. Thus, even in an image process is performed to a larger number of gradations, a high-speed process can be achieved with simple structure, and the error diffusion process can be effectively performed to a shift of dot apply positions.

摘要： Image processing apparatus and image processing method for formation of high quality image by high-speed error diffusion processing by execution of more complicated threshold condition processing in a simple manner. When error diffusion processing is performed on multivalued image data having plural density components and the result of processing is outputted, upon execution of error diffusion processing on a first density component among the plural density components, a threshold value used in the error diffusion processing is determined based on a density value of a second density component, then the error diffusion processing is performed on the first density component based on the determined threshold value, and the result of execution of the error diffusion processing is outputted. Further, upon execution of the error diffusion processing on the second density component among the plural density components, a threshold value used in the error diffusion processing is determined based on a density value of the first density component, then the error diffusion processing is performed on the second density component based on the determined threshold value, and the result of the error diffusion processing is outputted.

摘要： When a print command that designates a layout recording function by its upper layer, and designates a frame print function by its lower layer is transmitted from a camera to a printer, the printer determines a layout print function that prints a plurality of images on a single sheet, based on the upper layer. In a case where the printer can determine the lower layer of the command, the printer acquires details of a layout. In a case where the printer cannot determine the lower layer of the command, the printer determines a normal frame print function. The printer prints a normal layout image or special frame image in accordance with the determined layout of images.

摘要： In a case where a digital camera cannot understand or recognize a request received from a printer, the camera ignores the received request and discards the received request, and transmits a command that does not include any user instruction or print operation to the printer in place of the correct response to the request. In such case, the printer receives the command as the response to the request, and recognizes that the request transmitted by the printer cannot be accepted by the camera.
