Patent number: 6999115Abstract: An image taking apparatus, which can reduce the power consumption of the total system of the image taking apparatus without deteriorating image quality when an image is displayed on a liquid crystal display (LCD), is provided. In the image taking apparatus, the quantization bit number at an analog to digital (A/D) converter and the signal processing bit number at a digital signal processor (DSP) are variable. With this, at an LCD displaying mode that video signals are displayed on the LCD, the quantization bit number at the A/D converter is reduced and also the signal processing bit number at the DSP is reduced to the same bit number at the A/D converter. With this operation, at the LCD displaying mode, the power consumption at the A/D converter and the DSP is reduced, therefore the power consumption of the total system of the image taking apparatus is largely reduced.Type: GrantFiled: November 7, 2000Date of Patent: February 14, 2006Assignee: NEC CorporationInventor: Satoshi Katoh

Patent number: 6664992Abstract: A master making device includes a thermal head with heat generating elements and a platen roller. While the head and platen roller convey a thermosensitive medium in a subscanning direction perpendicular to a main scanning direction, the heat generating elements selectively generate heat in order to perforate the medium in accordance with an image signal. The head includes a stepped portion formed at a medium outlet side in the subscanning direction. The edges of the heat generating elements adjoining the medium outside side are located at a distance of 0.018 mm to 0.5 mm from the end of the stepped portion adjoining the above edges. It is not necessary to position the head with respect to an effective nip between it and the platen roller by a troublesome procedure. Further, the distance over which the perforated medium is conveyed is reduced to obviate the reduction or contraction of an image ascribable to the sticking of the medium to the head.Type: GrantFiled: March 17, 2000Date of Patent: December 16, 2003Assignee: Tohoku Ricoh Co., Ltd.Inventors: Yasumitsu Yokoyama, Yasunobu Kidoura, Satoshi Katoh, Yoshiyuki Shishido
