Abstract: PURPOSE:To make it possible to adaptively and detailedly change an area to be quantized in accordance with a pattern, to detailedly quantize an important transformation coefficient and to obtain high picture quality. CONSTITUTION:A blocking circuit 12 divides image data into plural image blocks each of which consists of nXn data in spatial arrangement. A discrete cosine transformation (DCT) circuit 13 rectangularly transforms the image data of each image block by means of a cosine function. An area determining circuit 50 divides a transformation coefficient area into at least two parts and determines respective areas so that the absolute sum of the transformation coefficients of respective areas becomes a prescribed rate. Each quantizer Qm has the combination of mutually different quantizing width values and quantizes a transformation coefficient by changing the quantizing width in each area. A selector 14b selects an output from the quantizer Qm with the minimum quantizing width in which the data volume of quantized data in the prescribed number of image blocks is less than a prescribed value based upon a control signal outputted from a control circuit 14c.

Title: Led print head
Inventor: MURANO SHUNJI
IPC: H01L21/60
Filed: 1991-12-30
Abstract: PURPOSE:To make the LED array of an LED print head smaller and to prevent defective wire bonding to the LED array. CONSTITUTION:Second bonding to an LED array is performed, and first bonding to an LED array mounting board is performed. The wire thickness delta along a capillary periphery mark at the second bonding is made 1/8-1/3 of the wire diameter; 1/6-1/4 is desirable. In the second bonding, the spread of wire of the bonded parts is smaller than that in the first bonding, and the larger delta is the smaller the spread is. As a result of this, it becomes possible to reduce the size of a bonding pad and the LED array. Besides, it becomes possible to increase bonding strength and to reduce the impact to the LED array simultaneously, by making the thickness delta 1/8-1/3 of the wire diameter.
