Publication number: 20130063513Abstract: A liquid ejection apparatus includes a liquid ejection head, a conveyor, a recording controller, and a flashing controller. The conveyor conveys a recording medium along a conveyance path. The recording controller causes the conveyor to convey a recording medium, and controls liquid ejection from the liquid ejection head to form an image on the recording medium based on image data. The flashing controller causes the conveyor to temporarily stop conveyance of the recording medium, and causes liquid ejection from the liquid ejection head based on drive data which is unrelated to image formation. The flashing controller determines timing for executing a subsequent flashing control so that, within a print enforceable period between one flashing control and the subsequent flashing control, the number of pages subjected to image formation based on image data increases with a decrease in time interval between image formation on one page and on another page.Type: ApplicationFiled: September 10, 2012Publication date: March 14, 2013Applicant: BROTHER KOGYO KABUSHIKI KAISHAInventor: Shuichi TAMAKI

Publication number: 20130063556Abstract: Techniques are provided for generating depth estimates for pixels, in a series of images captured by a single camera, that correspond to the static objects. The techniques involve identifying occlusion events in the series of images. The occlusion events are events in which dynamic blobs are at least partially occluded, by static objects, from view of the camera. The depth estimates for pixels of the static objects are generated based on the occlusion events and depth estimates associated with the dynamic blobs. Techniques are also provided for generating the depth estimates associated with the dynamic blobs. The depth estimates for the dynamic blobs are generated based on how far down, within at least one image, the lowest point of the dynamic blob is located.Type: ApplicationFiled: September 7, 2012Publication date: March 14, 2013Applicant: PRISM SKYLABS, INC.Inventors: Steve Russell, Ron Palmeri, Robert Cutting, Doug Johnston, Mike Fogel, Robert Cosgriff
